Custom Authentication module with Java code
by Jungtae Kim 25 Mar '16

25 Mar '16

Hello, I'm new to Kamailio. I'm trying to make my own auth module to check if incoming SIP messages are sighed with a correct key. I want to do this by calling a Java code snippet. I found app_java module but I can't figure out if this will support my usecase. Does app_java allow me to call Java code from another module? If not, what can I do to meet my use case? My token verification code is written in Java, so I'd like to reuse my code if possible. Thanks

Problem with authdb and view(?)
by Jon Bonilla (Manwe) 25 Mar '16

25 Mar '16

Hi all I've created a "subscriber" table which is a view of a asterisk sippeers table. The view is created as follows: create view subscriber as select id, name as username, fromdomain as domain, secret as password, email as email_address, md5secret as ha1, md5secret as ha1b, NULL as rpid from sippeers where type="friend"; and one of the resulting subscribers looks like this: *************************** 5. row *************************** id: 100022 username: user domain: domain.com password: plain or empty email_address: user(a)domain.com ha1: 3a4f5cc8dc0efb0d899cawe4dec9ea08 ha1b: 3a4f5cc8dc0efb0d899cawe4dec9ea08 rpid: NULL But when I try to register I get ERROR in the logs: New request - M=REGISTER R=sip:domain.com F=sip:user@domain.com ERROR: db_mysql [km_dbase.c:123]: db_mysql_submit_query(): driver error on query: Unknown column 'md5secret' in 'field list' ERROR: <core> [db_query.c:132]: db_do_query_internal(): error while submitting query ERROR: auth_db [authorize.c:187]: get_ha1(): failed to query database Is there any problem with views?

Multiple LCR instances with LCR module
by DanB 25 Mar '16

Hey Guys, I was wondering if any of you use multiple LCR instances with LCR module since I could see that the documentation allows it, however for some reason the queries to load data (both on restart or kamcmd lcr.reload) somehow hardcode the value of 1 inside: """ select `gw_name`,`ip_addr`,`port`,`uri_scheme`,`transport`,`params`,`hostname`,`strip`,`prefix`,`tag`,`flags`,`defunct`,`id` from `lcr_gw` where `lcr_id`=0 select `gw_name`,`ip_addr`,`port`,`uri_scheme`,`transport`,`params`,`hostname`,`strip`,`prefix`,`tag`,`flags`,`defunct`,`id` from `lcr_gw` where `lcr_id`=1 select `id`,`prefix`,`from_uri`,`stopper`,`enabled`,`request_uri` from `lcr_rule` where `lcr_id`=1 select `rule_id`,`gw_id`,`priority`,`weight` from `lcr_rule_target` where `lcr_id`=1 """ My kamailio version: """ # kamailio -V version: kamailio 4.3.5 (x86_64/linux) flags: STATS: Off, USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, USE_RAW_SOCKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, DBG_QM_MALLOC, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLACKLIST, HAVE_RESOLV_RES ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144, MAX_LISTEN 16, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: unknown compiled with gcc 4.9.2 """ Many thanks in advance for any kind of tip!

kamailio memory issue
by Volodymyr Rykhva 25 Mar '16

25 Mar '16

Hi, I have started using kamailio recently. Added to db almost 100K users. And now I am trying to increase shared and private memory with this command when server is running: kamailio -M 12 -m 128. But then I check it with `kamailio -l` and the same values (64 and 8 respectively) are there. Can I change it with config? or what I do wrong. And what's the purpose of child process? - Will kamailio process requests faster if I set child=32 (for example)? Thanks and best regards, Volodymyr

dynamic weighting for dispatcher
by Brooks Bridges 24 Mar '16

24 Mar '16

So I'm building a load balancer solution that needs to monitor remote devices at a specific interval via snmp for certain data (channels and cps) and use that data to create a dynamically updated weight for each of the destinations. I can't find any reasonable mechanism for updating the weight attribute in the dispatcher module itself without having to do some hacky "update the database column then trigger dispatcher.reload" script, which I very much want to avoid. Is this something I should just be thinking of ditching the dispatcher module and rolling my own design or am I missing something obvious?

Dispatching Registrations to Weight based servers
by SamyGo 24 Mar '16

24 Mar '16

Hi All, I'm having a wee little bit of difficulty in trying to load-balance registrations to multiple servers based on their weights. Kind of similar scenario as discussed in this thread: http://lists.sip-router.org/pipermail/sr-users/2014-December/086235.html The problem I'm facing is that dispatcher is always choosing the first destination from the group. I do suspect that dispatcher is not considering registrations as load at all and only counts INVITES as load. If above is correct then is there a way to use dispatcher to count registrations as load ? Thanks, Sammy

Kamailio 5.0 - B2BUA
by Alex Balashov 24 Mar '16

24 Mar '16

Hi, I wanted to raise the possibility of an inline signalling-only B2BUA component to Kamailio. I know that's an extremely poor fit for Kamailio, and not at all what it's supposed to do. And there are many things about the OpenSIPS B2BUA module that reveal how awkwardly it is situated, as a square peg in a round hole. I myself am philosophically opposed to a B2BUA in Kamailio to the threshold of physical violence. However, the reason I bring it up for discussion is that there are very few viable, high-performance signalling-only B2BUA alternatives that are FOSS. There is enormous demand for a B2BUA, mainly for topology concealment purposes, from the short-duration traffic industry, which many users of Kamailio deal with. It's why a lot of them end up going to OpenSIPS; they need the B2BUA, and prefer to consolidate on one OpenSER brand. Anyone who has tried to run high-CPS traffic through the existing FOSS signalling-only B2BUAs out there situated in front of Kamailio has discovered, sometimes in a very financially painful way, that: - FreeSWITCH falls over at around +/- 300 CPS. This is with RTP relay disabled -- signalling-only. It requires horizontally scaling a large number of FreeSWITCH boxes to meet a capacity requirement of, say, 2000 CPS, which is unfortunate given the favourable proposition offered by Kamailio for the infrastructure unit economics. In other words, it's ironic to have to build a fleet of 10 FreeSWITCH boxes for the 1% problem of topology concealment when Kamailio can otherwise churn through 2000 CPS with no issues. - SEMS' 'sbc' module is a good candidate and can handle the load, but Frafos offers practically no support for it, with all efforts focused on their commercial ABC SBC product. That's very understandable, but just not practical given the high technical knowledge SEMS requires to deploy and maintain in this capacity. - None of the other userspace B2BUA folk traditions can handle the load. So, like I said, I personally recoil in shock and horror at the idea of introducing a B2BUA into something that was designed to be anything but a B2BUA. But, there is a huge market opportunity for this functionality in North America, and at the moment, users who need it are mostly ending up in OpenSIPS land. -- Alex -- Alex Balashov | Principal | Evariste Systems LLC 303 Perimeter Center North, Suite 300 Atlanta, GA 30346 United States Tel: +1-800-250-5920 (toll-free) / +1-678-954-0671 (direct) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/

kamailio in a multi-site configuration
by Sébastien Brice 24 Mar '16

24 Mar '16

Hi everyone i am installing Kamailio to scale asterisk on a remote hosted server in a way to manage calls dialogs in a real-time fashion. (and to manage many customers) Several users (maybe 80) are working at the head-office and i want them register their hardphone on the remote Kamailio Ipbx, to free them of ours end-of-life PABX (alcatel-Lucent). Can kamailio help me to achieve that ? What kind of software have I to install locally (mysql to replicate the master mysql db? a replicated asterisk instance?) ? Taking into consideration disaster recovery plan What could be my options to maintain internal call if my internet provider get down by exemple. thx you for your idea.

set_advertised_address() / set_advertised_port() + PVs?
by Alex Balashov 23 Mar '16

23 Mar '16

Hello, I have a need to deploy Kamailio in AWS in a scenario of this sort: [Public Internet] <---> Kamailio <---> (Internal AWS servers) In such a scenario, Kamailio would be multihomed. Furthermore, in addition to sending out of two distinct network interfaces, the networking idiosyncrasies of AWS needs to be taken into account. AWS hosts only have an RFC1918 address homed natively, front-ended by 1:1 NAT externally. Normally, this is taken care of by advertised_address, which allows Kamailio to make outward representations about the network address by which it can be reached that are different to the IP to which it is bound. The problem here is that I need to do this conditionally, only on traffic going out the public interface. It should not be done on messages going to the "internal AWS servers". So, the questions that arise are: 1. Is this sane? Any unforeseen effects, e.g. vis-a-vis RR, provided enable_double_rr is enabled and that two genuinely different network interfaces are used? 2. Do set_advertised_address()/set_advertised_port() accept PV arguments, or are they pre-PV "core function folk traditions" in the same way as rewritehostport() and force_send_socket()?

Hello, I am trying to set up a Kamailio in Bridge Mode with two interfaces using rtpproxy. The problem I have is SDP information port and IP is not updated from outside to inside. But on the other hand the SDP is rewrited from inside to outside.

Hi everyone, I am trying to forward registration from one kamailio instance to another one eg. UA1 <---> kamailioB <------> kamailioA I am trying to register on `kamailioA` with UA1. I have UA1 registered on kamailioA. I am routing SIP messages by adding this to `request_route` block: if (uri != myself) { forward(otherKamailioIP, 5060); } Where I am using as `otherKamilioIP on kamailioA the kamailioB IP address and vice versa. I can clearly see in Wireshark, that the SIP messages are routed correctly but I am getting 401 Unauthorized which is sent from kamailioA to kamailioB and then from kamailioB to UA1. I printed value of `auth_check` following this http://lists.sip-router.org/pipermail/sr-users/2014-November/085851.html and I am getting return code of `-1` which is according to the documentation http://kamailio.org/docs/modules/4.2.x/modules/auth_db.html#auth_db.f.www_a… the GENERIC ERROR. I don't know what to do next. Does anyone encounter this kind of error before? Thanks in advance

processing ACK
by jaflong jaflong 23 Mar '16

23 Mar '16

Hi Everyone I am manually processing sdp and handling media so I want to repond to ACK myself instead of forwarding on for media server. I catch the method=="ACK" condition. From within this condition how do I retrieve avp variables that were set in the INVITE. Requesting $avp("myvar") comes out as null. Also what function can I run so the ACK is replied to properly so it stops resending 200 OK of the Invite.

Kamailio 5.0 - Better way of dealing with stateless CANCELs
by Alex Balashov 21 Mar '16

21 Mar '16

Currently (AFAIK), restarting Kamailio amidst production call processing is basically "safe"; except for no availability during the few seconds it takes to restart (which will just result in retransmissions until it is available), most things will happen "correctly" after restart even though TM state has been lost: (1) Initial requests will be routed as initial requests always were; (2) In-dialog requests will be loose-routed as sequential requests always were; (3) Replies to open transactions will fall back to stateless routing but will be delivered correctly to their destinations based on SIP fundamentals (i.e. Via). (4) rtpproxy & rtpengine control messages are grouped by Call-ID, so also stateless. If the proper destroy/remove functions are not called from failure_route[] due to lack of TM state, it's not so bad; rtpproxy & rtpengine will see an RTP timeout after a while and expire the bindings on their own. If dialog state is used, it will be lost, but assuming one is willing to live with that, it's okay. I don't know if there has been any work done to create a persistence layer for dialog that can be re-read completely on startup, and if it actually works - does it? - but it's a relatively small price to pay if it's important to integrate a change into production in the middle of the day. The one exception is CANCEL handling. CANCEL is a special animal, since it's a hop-by-hop (branch-level) request, so CANCELs sent from a caller apply to the 'caller -> Kamailio' branch. Kamailio generates separate CANCELs endogenously for one or more 'Kamailio -> gateway' branches. Stateful CANCEL handling with TM is implemented using t_check_trans() or t_relay_cancel(). For example, in the stock config[1] # CANCEL processing if (is_method("CANCEL")) { if (t_check_trans()) { route(RELAY); } exit; } Or, as in our case, more folklorically: if(is_method("CANCEL")) { if(!t_relay_cancel()) { # Corresponding INVITE transaction found, but error # occurred. sl_send_reply("500", "Internal Server Error"); exit; } # Corresponding INVITE transaction for CANCEL was not # found. exit; } In both cases, the corresponding INVITE transaction must exist. Unfortunately, there's no good alternative. According to RFC 3261 Section 16.11 ("Stateless Proxy"): Stateless proxies MUST NOT perform special processing for CANCEL requests. They are processed by the above rules as any other requests. So, in other words, route_logic(CANCEL) == route_logic(initial INVITE). Sometimes, this is possible - with considerable config logic labour - but other times the path taken by the CANCEL is not so deterministic, as for example with round-robin load balancing, random distribution, complex LCR, etc. One is basically left in these situations with the choice of implementing one's own Call-ID/branch => destination persistent state database of some kind, which is, to put it mildly, complicated and undesirable. Now, if the INVITE transaction receives a final negative reply, this will get back to the calling UAC, and it will process it correctly. However, some calls get answered with 2xx. Many UACs will behave reasonably in this situation: when they don't receive a 200 OK for their CANCELs but later receive an answer, they will go ahead and send the end-to-end ACK, then BYE the call. However, they cannot be reliably counted upon to do this. Some simply get drop the INVITE transaction after their CANCEL has gone unreplied for a short time, regardless of whether they receive a final negative reply for it. Is there a better way? Perhaps a feature can be devised by which Kamailio keeps some kind of lightweight and restart-persistent map to which to send the CANCELs? Or perhaps TM is due for a feature that allows the shm transaction table to be dumped to disk and persisted across restarts? Comments welcome. Also, if I'm missing something, please let me know! -- Alex [1] https://github.com/kamailio/kamailio/blob/master/etc/kamailio.cfg#L466 -- Alex Balashov | Principal | Evariste Systems LLC 1447 Peachtree Street NE, Suite 700 Atlanta, GA 30309 United States Tel: +1-800-250-5920 (toll-free) / +1-678-954-0671 (direct) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/

Missing pipelimit values in data returned by JSONRPC-S
by Brooks Bridges 21 Mar '16

21 Mar '16

When trying to pull a list of pipes and their current values by using pl.dump via the JSONRPC-S module, I am only getting the last result in the reply as opposed to an array. If I use the CLI RPC interface I get the data I expect. Here's a sanitized example: [root@server1 ~]# kamcmd pl.stats PIPE: id=user_1 load=0 counter=29 PIPE: id=user_2 load=0 counter=108 PIPE: id=user_3 load=0 counter=18 PIPE: id=user_4 load=0 counter=0 PIPE: id=user_5 load=0 counter=1 PIPE: id=user_6 load=0 counter=2 PIPE: id=user_7 load=0 counter=0 PIPE: id=user_8 load=0 counter=84 PIPE: id=user_9 load=0 counter=26 PIPE: id=user_10 load=0 counter=0 PIPE: id=user_11 load=0 counter=23 PIPE: id=user_12 load=0 counter=9 PIPE: id=user_13 load=0 counter=23 PIPE: id=user_14 load=0 counter=0 PIPE: id=user_15 load=0 counter=107 PIPE: id=user_16 load=0 counter=10 PIPE: id=user_17 load=0 counter=28 PIPE: id=user_18 load=0 counter=45 PIPE: id=user_19 load=0 counter=7 PIPE: id=user_20 load=0 counter=0 PIPE: id=user_21 load=0 counter=12 PIPE: id=user_22 load=0 counter=94 PIPE: id=user_23 load=0 counter=14 PIPE: id=user_24 load=0 counter=7 PIPE: id=user_25 load=0 counter=18 PIPE: id=user_26 load=0 counter=46 PIPE: id=user_27 load=0 counter=45 PIPE: id=user_28 load=0 counter=50 PIPE: id=user_29 load=0 counter=2 PIPE: id=user_30 load=0 counter=2 [root@server1 ~]# curl -s --header 'Content-Type: application/json' --data-binary '{"jsonrpc": "2.0", "method": "pl.stats"}' http://1.2.3.4:5060/jsonrpc {"jsonrpc":"2.0","result":"PIPE: id=user_30 load=0 counter=2"} [root@server1 ~]# The jsonrpc config and event route is about as basic as you can get: modparam("jsonrpc-s", "pretty_format", 0) modparam("jsonrpc-s", "transport", 1) event_route[xhttp:request] { xlog("L_INFO", "[R-HTTP-REQUEST:$si] -> Got HTTP request\n"); if($hu =~ "^/jsonrpc") { xlog("L_INFO", "[R-XHTTP-REQUEST:$si] -> Handling JSON RPC request: $hu\n"); jsonrpc_dispatch(); } else { xhttp_reply("404", "Not Found", "text/html", ""); } } Should the JSONRPC-S module be returning this as an array instead of just a single value?

Removing Via and Record-Route headers
by Marrold 21 Mar '16

21 Mar '16

Hi, Is there any way to remove Via and Record-Route headers from requests sent to an endpoint and update the contact header, but have Kamailio statefully remember where the replies need to route? I imagine this would involve mangling the packets slightly to behave similar to a B2BUA. My motivations, in order of priority - 1) Reduce UDP packet size to avoid MTU limitations 2) Improve interoperability, don't expect end points to be able to properly parse / process many via / record-route headers 3) Hide topology. If someone could point me in the right direction in terms of configuration or modules, that would be great. Thanks

What to read after RFC 3261 to get started with Kamailio.
by Oivvio Polite 21 Mar '16

21 Mar '16

I want to get started with Kamailio. So far I've understood that I really need to grok SIP before tackling Kamailio so I'm reading the book "SIP demystified" as the starting point of my Kamailio journey. After that I will read RFC 3261. After that I think it's time to read something that will give me good understanding of how to actually implement applications with Kamailio. Searching Amazon for Kamailio returns "Building Telephony Systems with OpenSER" as the results that seems to be most specific to Kamailio. This book is from 2008. Is it still relevant or is it better to go with the online docs? regards, Oivvio

problem with relaying after t_susped() and t_continue()
by Uri Shacked 21 Mar '16

21 Mar '16

I have a problem when using t_suspend() and t_continue(). Let's say I would like to have a 5 sec delay before relaying an INVITE. For example the following code: * route[MYROUTE] {* * t_newtran();* * if (is_method("INVITE")) {* * t_reply("100", "Trying");* * t_reply("180", "In Queue");* * $sht(a=>$ci::t_index) = $T(id_index);* * $sht(a=>$ci::t_label) = $T(id_label);* * $sht(a=>$ci::t_suspended) = 1;* * xlog("L_WARN","SUSPENDING t_index = $sht(a=>$ci::t_index) and t_label = $sht(a=>$ci::t_label)");* * t_suspend();* * sleep(5);* * if (t_is_canceled()) drop;* * $sht(a=>$ci::t_suspended) = 0;* * t_continue("$avp(t_index)","$avp(t_label)","1");* * }* * route(RELAY);* * exit;* * }* * route[1] {* * xlog("L_WARN","After transaction continue\n");* * route(RELAY);* * exit;* * }* When using this code, I get the following error: Mar 9 16:49:32 mysip /usr/local/sbin/kamailio[5260]: WARNING: <script>: After transaction continue Mar 9 16:49:32 mysip /usr/local/sbin/kamailio[5260]: ERROR: <core> [resolve.c:1693]: sip_hostport2su(): could not resolve hostname: "mysip" Mar 9 16:49:32 mysip /usr/local/sbin/kamailio[5260]: ERROR: tm [ut.h:319]: uri2dst2(): failed to resolve "mysip" Mar 9 16:49:32 mysip /usr/local/sbin/kamailio[5260]: ERROR: tm [t_fwd.c:1711]: t_forward_nonack(): ERROR: t_forward_nonack: failure to add branches Mar 9 16:49:32 mysip /usr/local/sbin/kamailio[5260]: ERROR: sl [sl_funcs.c:363]: sl_reply_error(): ERROR: sl_reply_error used: Unresolvable destination (478/SL) Mar 9 16:49:32 mysip /usr/local/sbin/kamailio[5260]: BUG: tm [t_lookup.c:1481]: t_unref(): tm: t_unref: REQ_ERR DELAYED should have been caught much earlier for 0x7fd4e727a468: 27 (hex 1b) If I try to t_continue() without any route: t_continue("$avp(t_index)","$avp(t_label)",""); The call is working great and the following error pops up: Mar 9 17:10:36 mysip /usr/local/sbin/kamailio[5830]: ERROR: tmx [tmx_mod.c:635]: w_t_continue(): empty action lists in route block [] Am I doing something wrong? My other question is regarding CANCEL. Let's assume I suspended the INVITE and in these 5 sec I received CANCEL for it. Is there a short and elegant way to remove the transaction from suspension? For now I do: * if (is_method("CANCEL")) {* * if (t_check_trans()) {* * if($sht(a=>$ci::t_suspended) == 1) {* * t_continue("$sht(a=>$ci::t_index)","$sht(a=>$ci::t_label)","");* * xlog("L_WARN","After transaction continue\n");* * }* * route(RELAY);* * }* * exit;* * }* Thanks, Uri

srv_query question
by Vasiliy Ganchev 18 Mar '16

18 Mar '16

Hi folk! I am trying to implement srv_query usage in my script (server is based on Kamailio+Asterisk). The task: when outgoing REGISTER comes from Asterisk (outgoing trunk to operator), and R-URI consists domain name, need to store all ip-addresses of remote side (for following use) Currently, this works using dns_query, and storing in htable structure with remote IPs. But if remote side use SRV, I do not have all IPs Trying to use srv_query function from ipops, I am stuck with following: - srv_query(srvcname, pvid) to get srvcname - for example, "_sip._tcp.example.com", I need to provide, NAPTR record lookup (that is according to RFC3263, and Kamailio does this in core, while request processing) but I see no way how to make NAPTR lookup from script (not involving non Kamailio tools) Looking in mail list archive, found nothing that could help. What I am missing, is there an easy solution, how to cope with my case? Would appreciate any suggestion or idea. Cheers! -- View this message in context: http://sip-router.1086192.n5.nabble.com/srv-query-question-tp146546.html Sent from the Users mailing list archive at Nabble.com.

Kamailio and UCARP with Multiple VIPs defined
by Jonathan Hunter 15 Mar '16

15 Mar '16

Hi Guys, Using Centos 6.7, kamailio 4.2 and Ucarp I am testing multiple VIPs on the same server and having some issues. I have ucarp running, with 1 Public and 1 Private VIP defined, and both are pingable and failover in a cluster. The Public is for Subscribers to Register with, and the Private for Communication to the Asterisk media servers behind it. My problem is kamailio when started states its listening on both the VIPS, however when I try and force_socket over the Private IP address, it states ERROR: <core> [forward.c:218]: get_out_socket(): no socket foundMar 1 20:04:35 bt1proxy1 /usr/sbin/kamailio[20372]: ERROR: <core> [forward.c:220]: get_out_socket(): no corresponding socket found for(udp:10.70.0.72:5080)Mar 1 20:04:35 bt1proxy1 /usr/sbin/kamailio[20372]: ERROR: tm [t_fwd.c:520]: prepare_new_uac(): ERROR: can't fwd to af 2, proto 1 (no corresponding listening socket) This is when listening on the VIP which is 10.70.0.75 and I also look to force_socket out of this IP. It just doesnt work, however if I use the physical interface on the server, that being 10.70.0.70, it works fine and forwards requests on the Private LAN. I have added net.ipv4.ip_nonlocal_bind = 1 to sysctl.conf as well but no joy. If 1 VIP is defined I have no issue, its just with 2, has anyone had this issue before ? Any help would be great. Many thanks Jon

RTPPROXY error message
by Kevin Greene 15 Mar '16

15 Mar '16

Hi: I am sure this has been answered before on this list and I have tried the basic answers I got from Google without any luck. Any suggests would be great. The Kamailio host is running Oracle Linux 6.7 (64 bit) and is fully patched as of today. The Kamailio version is: Server:: kamailio (4.3.4 (x86_64/linux)) Build:: mi_core.c compiled on 14:25:16 Nov 25 2015 with gcc 4.4.7 I have two major issues: I am seeing this on my Kamailio log: Mar 14 21:55:33 sipserver /usr/sbin/kamailio[24005]: ERROR: rtpproxy [rtpproxy.c:1681]: send_rtpp_command(): can't send command to a RTP proxy Mar 14 21:55:33 sipserver /usr/sbin/kamailio[24005]: ERROR: rtpproxy [rtpproxy.c:1716]: send_rtpp_command(): proxy <udp:127.0.0.1:7722> does not respond, disable it Mar 14 21:55:33 sipserver /usr/sbin/kamailio[24005]: WARNING: rtpproxy [rtpproxy.c:1573]: rtpp_test(): can't get version of the RTP proxy Mar 14 21:55:33 sipserver /usr/sbin/kamailio[24005]: WARNING: rtpproxy [rtpproxy.c:1610]: rtpp_test(): support for RTP proxy <udp:127.0.0.1:7722> has been disabled temporarily So the initial thought is that the proxy is not running, however I can see the proxy is alive: [root@sipserver boot]# ps -All | grep rtpproxy 5 S 498 2843 1 1 80 0 - 32524 hrtime ? 01:29:06 rtpproxy When I do "netstat -a", I can see 24 established connections. This is a small sample: udp 0 0 localhost:47937 localhost:rtpproxy ESTABLISHED udp 0 0 localhost:38746 localhost:rtpproxy ESTABLISHED udp 0 0 localhost:33660 localhost:rtpproxy ESTABLISHED So I am not sure what is going on. The second problem: I see this in the Kamailio log: Mar 14 22:05:33 sipserver /usr/sbin/kamailio[24000]: ERROR: db_mysql [km_dbase.c:124]: db_mysql_submit_query(): driver error on query: PROCEDURE kamailio.kamailio_rating does not exist (1305) Mar 14 22:05:33 sipserver /usr/sbin/kamailio[24000]: ERROR: <core> [db_query.c:181]: db_do_raw_query(): error while submitting query Mar 14 22:05:33 sipserver /usr/sbin/kamailio[24000]: ERROR: sqlops [sql_api.c:265]: sql_do_query(): cannot do the query [call kamailio_rating('default')] When I tried to create the database originally, the script that was part of the package would not work. I therefore manually created the database so I am thinking that something got left out. I have been over the schema and I am not sure what is missing. The database is MySQL (5.5) running in a separate host. Does anyone have an idea where to look what is missing? I was told that there is some sort of script that can "repair" the Kamailio schema in the database but I have not been able to find this magical script. Thanks. Kevin

kamailio with external database to replace from uri
by Thibault Gueslin 14 Mar '16

14 Mar '16

I am using kamailio without database. It works fine. For some scenario, I would like to replace the from uri (using mac_replace_from works fine) but using data I can accessed with a REST API. I want to have different origination depending on the sipusername. I need to have some synchronous request. Have someone already these type of behaviour ? Regards Thibault

Re: [SR-Users] Registration Failure - IMS

Hi Cristina, > But I have another problem related to registration process. After REGISTER- > 401 Unauthorized-REGISTER-200 OK, the IMS client sends the SUBSCRIBE > message (for the "reg" event package subscription) to the S-CSCF, the latter > replies with NOTIFY and the client correctly responds with 200 OK.

I have now spent some time to reproduce the issue. First of all: I had to adapt module reg_mod.c in ims_registrar_pcscf, because it containes a hardcoded P-CSCF address: str pcscf_uri = str_init("sip:pcscf.ims.smilecoms.com:4060"); which is only valid for smilecoms. Did you also change that? Then I got exactly the same problem. I found that the P-CSCF config causes in the part "# Check for Subsequent requests:" a reject " sl_send_reply("404","Not here");" I have doubts that this is correctly designed and have to dig deeper into the logic of the config-file. Fact is: the NOTIFY request does not contain a Route header and as it not an ACK it goes straight to the reject. Maybe any IMS expert can shed some light on this code as shown below: # Check for Subsequent requests: if (has_totag()) { # sequential request withing a dialog should # take the path determined by record-routing if (loose_route()) { if ($route_uri =~ "sip:mo@.*") { setflag(FLT_MO); } if(!isdsturiset()) { handle_ruri_alias(); } # RTP-Relay, if necessary route(RTPPROXY); t_relay(); } else { if ( is_method("ACK") ) { if ( t_check_trans() ) { # no loose-route, but stateful ACK; # must be an ACK after a 487 # or e.g. 404 from upstream server t_relay(); exit; } else { # ACK without matching transaction ... ignore and discard exit; } } sl_send_reply("404","Not here"); } exit; BR Franz

Hi, we have a load balancer which is handling a lot of SIP traffic all day. There's always 20-40 Mbit SIP traffic going through. From time to time we see in our logs messages like these: Sep 16 09:46:28 ecker /usr/sbin/kamailio[25505]: ERROR: <core> [udp_server.c:591]: udp_send(): ERROR: udp_send: sendto(sock,0x7f2d9d6b3ce0,1321,0,46.237.225.126:5060,16): Operation not permitted(1) Sep 16 09:46:38 ecker /usr/sbin/kamailio[25194]: ERROR: <core> [udp_server.c:591]: udp_send(): ERROR: udp_send: sendto(sock,0x7efc982b8fc8,420,0,82.113.121.183:35794,16): Operation not permitted(1) Sep 16 09:46:40 ecker /usr/sbin/kamailio[25505]: ERROR: <core> [udp_server.c:591]: udp_send(): ERROR: udp_send: sendto(sock,0x7f2d9d6b3ce0,1338,0,5.158.137.9:55067,16): Operation not permitted(1) Sep 16 09:46:44 ecker /usr/sbin/kamailio[25183]: ERROR: <core> [udp_server.c:591]: udp_send(): ERROR: udp_send: sendto(sock,0x7efc982d9f48,450,0,178.165.131.197:37515,16): Operation not permitted(1) Sep 16 09:46:49 ecker /usr/sbin/kamailio[25643]: ERROR: <core> [udp_server.c:591]: udp_send(): ERROR: udp_send: sendto(sock,0x7f93fb624530,496,0,172.56.7.69:25643,16): Operation not permitted(1) Sep 16 09:46:55 ecker /usr/sbin/kamailio[25335]: ERROR: <core> [udp_server.c:591]: udp_send(): ERROR: udp_send: sendto(sock,0x7f41632cda98,598,0,80.215.234.139:3396,16): Operation not permitted(1) Sep 16 09:46:56 ecker /usr/sbin/kamailio[25345]: ERROR: <core> [udp_server.c:591]: udp_send(): ERROR: udp_send: sendto(sock,0x7f41632f4840,459,0,94.197.120.191:8225,16): Operation not permitted(1) I know that these messages can be produced by iptables blocking the outbound traffic.

Has anyone ever seen this? It looks like a load thing, because at weekends there are significantly less errors. Thanks, Sebastian

SIP Autentication Failed
by Bruno Henrique Gomes Gouvêa 11 Mar '16

11 Mar '16

Hello, First excuse any mistakes in English. I'm working on a platform that makes use of integrated Kamailio with asterisk (Elastix mt). This platform allows the login of my SIP clients via the extension number and the client's domain, where the kamailio after authentication change the username to sip EXTENSION + _ + DOMAIN (expected by Asterisk) and sends to the asterisk. I need the client can also send the sip user in standard EXTENSION + _ + DOMAIN, for it changed the view subscriber to also return a username record in the format that the softphone is sending, but the platform still seems not authenticate the REGISTER using new way functions in auth_check ("$ FD", "subscriber", "0") and auth_challenge ("$ FD", "0"). Thus works: Login: 101 Domain/server: pabx999999.ligou.me Password: PASSWORD_PLAIN This way does not work: Login: 101_pabx999999.ligou.me Domain/server: pabx999999.ligou.me Password: PASSWORD_PLAIN Already got a good look at the documentation and could not find the problem, could give me some help?

rare impossibility to send requests to TLS connected peer
by Vasiliy Ganchev 09 Mar '16

09 Mar '16

Hi folk! Have a rare issue with tls connections. Have a server with 100+ active tls connections, that are connected to separate TCP proxy, that listen on port 443. TCP proxy send sip traffic to Kamailio via localhost:5061. In this way all connections in Kamailio are considered from Localhost. Issue scheme: - UA-A (sip-phone, UDP/TCP/TLS) -> call -> sip server (Kamailio+Asterisk based) -> UA-B (sip phone, transport=TLS) - The troubles happened in part of flow to UA-B: --- kamailio script make lookup(location), find AOR for UA-B (here is OK) --- after t_relay, kamailio make branch_route logic and try to send INVITE to tcp socket --- HERE IS the trouble: connection seems to be opened, but Kamailio cannot send INVITE there (say: no open tcp connection found) --- Kamailio try to open tcp connection from itself, TCP proxy refuse it --- as a result - Kamailio answer 477 to Asterisk, and finish processing debug level 3 logs (from the point where Kamailio try to send INVITE in opened connection) Jan 25 14:32:43 /usr/sbin/kamailio[4722]: DEBUG: <core> [tcp_main.c:1463]: _tcpconn_find(): tcpconn_find: 0 port 60286 Jan 25 14:32:43 /usr/sbin/kamailio[4722]: DEBUG: <core> [ip_addr.c:243]: print_ip(): tcpconn_find: ip 127.0.0.1 Jan 25 14:32:43 /usr/sbin/kamailio[4722]: DEBUG: <core> [tcp_main.c:1820]: tcp_send(): tcp_send: no open tcp connection found, opening new one Jan 25 14:32:43 /usr/sbin/kamailio[4722]: DEBUG: <core> [ip_addr.c:243]: print_ip(): tcpconn_new: new tcp connection: 127.0.0.1 Jan 25 14:32:43 /usr/sbin/kamailio[4722]: DEBUG: <core> [tcp_main.c:1073]: tcpconn_new(): tcpconn_new: on port 60286, type 3 Jan 25 14:32:43 /usr/sbin/kamailio[4722]: DEBUG: <core> [tcp_main.c:1626]: _tcpconn_add_alias_unsafe(): _tcpconn_add_alias_unsafe: alias port 60286 for hash 2646, id 404319 Jan 25 14:32:43 /usr/sbin/kamailio[4722]: DEBUG: <core> [tcp_main.c:1626]: _tcpconn_add_alias_unsafe(): _tcpconn_add_alias_unsafe: alias port 60286 for hash 2728, id 404319 Jan 25 14:32:43 /usr/sbin/kamailio[4722]: DEBUG: <core> [tcp_main.c:1624]: _tcpconn_add_alias_unsafe(): _tcpconn_add_alias_unsafe: alias already present Jan 25 14:32:43 /usr/sbin/kamailio[4722]: DEBUG: <core> [tcp_main.c:1382]: tcpconn_add(): tcpconn_add: hashes: 2646:2728:0, 863 Jan 25 14:32:43 /usr/sbin/kamailio[4722]: DEBUG: tls [tls_server.c:184]: tls_complete_init(): Using TLS domain TLSc<default> Jan 25 14:32:43 /usr/sbin/kamailio[4722]: DEBUG: tls [tls_domain.c:700]: sr_ssl_ctx_info_callback(): SSL handshake started Jan 25 14:32:43 /usr/sbin/kamailio[4722]: ERROR: <core> [tcp_main.c:2742]: tcpconn_1st_send(): connect 127.0.0.1:60286 failed (RST) Connection refused Jan 25 14:32:43 /usr/sbin/kamailio[4722]: ERROR: <core> [tcp_main.c:2752]: tcpconn_1st_send(): 127.0.0.1:60286: connect & send for 0xb1d3b7e8 failed: Connection refused (111) Jan 25 14:32:43 /usr/sbin/kamailio[4722]: DEBUG: <core> [tcp_main.c:2947]: tcpconn_chld_put(): tcpconn_chld_put: destroying connection 0xb1d3b7e8 (404319, -1) flags 0060 Jan 25 14:32:43 /usr/sbin/kamailio[4722]: ERROR: tm [../../forward.h:247]: msg_send(): tcp_send failed Jan 25 14:32:43 /usr/sbin/kamailio[4722]: DEBUG: tm [t_fwd.c:1591]: t_send_branch(): t_send_branch: send to 127.0.0.1:60286 (3) failed Jan 25 14:32:43 /usr/sbin/kamailio[4722]: WARNING: tm [t_fwd.c:1610]: t_send_branch(): ERROR: t_send_branch: sending request on branch 0 failed Jan 25 14:32:43 /usr/sbin/kamailio[4722]: DEBUG: tm [t_funcs.c:358]: t_relay_to(): ERROR:tm:t_relay_to: t_forward_nonack returned error Jan 25 14:32:43 /usr/sbin/kamailio[4722]: DEBUG: tm [t_funcs.c:375]: t_relay_to(): -477 error reply generation delayed Jan 25 14:32:43 /usr/sbin/kamailio[4722]: DEBUG: tm [t_lookup.c:1526]: t_unref(): t_unref: delayed error reply generation(-477) Jan 25 14:32:43 /usr/sbin/kamailio[4722]: DEBUG: <core> [parser/msg_parser.c:339]: parse_headers(): parse_headers: flags=ffffffffffffffff Jan 25 14:32:43 /usr/sbin/kamailio[4722]: DEBUG: tm [t_reply.c:1670]: cleanup_uac_timers(): DEBUG: cleanup_uac_timers: RETR/FR timers reset Jan 25 14:32:43 /usr/sbin/kamailio[4722]: DEBUG: tm [t_reply.c:728]: _reply_light(): DEBUG: reply sent out. buf=0xb67c000c: SIP/2.0 477 Unfortun..., shmem=0xb1b676cc: SIP/2.0 477 Unfortun Jan 25 14:32:43 /usr/sbin/kamailio[4722]: DEBUG: tm [t_funcs.c:156]: put_on_wait(): DEBUG: put on WAIT Jan 25 14:32:43 /usr/sbin/kamailio[4722]: DEBUG: tm [t_reply.c:738]: _reply_light(): DEBUG: _reply_light: finished Additionally want to say, that suddenly we don't have clear reproduce, it happened only on 2 production servers, what are common conditions for issue: - transport=TLS - when issued call is done, I checked with netstat, the connection is alive - the issued device is re-REGISTERed as usual, in kamctl ul show I see registration before/during/after issued call - issue appear only when connection through our custom TCP proxy :443 (to Kamailio it is from 127.0.0.1:5061) - if connection switched to Kamailio 5061 directly - issue never (till now) reproduced - in one of the issued server - I noticed big number of tcp id.

Branching v4.4
by Daniel-Constantin Mierla 09 Mar '16

09 Mar '16

Hello, I am considering to branch v4.4 latest on March 10, after that the master branch can be used again for adding new features and fixes will be backported to branch 4.4. If it proves to worth branching earlier, it can be done. As an estimate date for the release of v4.4.0, a good candidate would be one of the days between March 22, 23 or 24. Any other suggestions or comments? Cheers, Daniel -- Daniel-Constantin Mierla http://twitter.com/#!/miconda - http://www.linkedin.com/in/miconda Kamailio Advanced Training, Berlin, March 7-9, 2016 - http://www.asipto.com

Kamailio 5.0 - Scripted DB Migrations
by Tim Chubb 08 Mar '16

08 Mar '16

As a suggestion for 5.0 having a scripted DB migration system would make upgrading much easier. Something like what Asterisk now uses (Alembic https://pypi.python.org/pypi/alembic) would be ideal, as it works in a DB agnostic manner and you would just have to ensure that there is a driver for the DB you wish to use. That way you would just update the definition script and select the target when you run the updater, and would allow kamailio a greater choice in backing DB's as once the script is written assuming a driver is available for you RDBMS the schema would be successfully ported. This would do away with maintaining separate MySQL, Postgres, Oracle, MSSQL scripts as well. The only issue I can think with a system like this is in the situation where hardcoded SQL strings are in the source and use a RDBMS specific function as that could cause some "fun" in debugging...

question about dlg_var

08 Mar '16

I want to distingguish 200 OK is for INVITE or reINVITE。 so I do this: request_route { if (is_method("INVITE") && !has_totag()) { $dlg_var(is_init_invite) = "1"; } } onreply_route { xlog("L_INFO","[$rs-$rr][is_init_invite:$dlg_var(is_init_invite)]"); if (is_method("INVITE") && t_check_status("200") && $dlg_var(is_init_invite) == "1") { # do somting $dlg_var(is_init_invite) = "0"; } xlog("L_INFO","[$rs-$rr][is_init_invite:$dlg_var(is_init_invite)]"); } What I confuse is： When I recive 100 Trying LOG is [100 - Trying][is_init_invite:0] [100 - Trying][is_init_invite:1] why is_init_invite is 0?

Kamailio design that needs one b2bua
by anthony gonzalez 08 Mar '16

08 Mar '16

Hello there, I'm designing and implementing a kamailio solution for sip routing between several softswitch based on prefixes. IIn this setup i will need an b2bua in order to do topology hiding and also to make transparent the call transfer between phones registered in kamailio and softswitches(that doesn't support very well REFER messages). I was searching what solution should I use and I found 3 opensource solutions that for me seems to be acceptable: Sems. Freeswitch. Opensips with module b2bua. Based on your experience and contemplating the stability, performance and support, what is the solution that you advice me ? Thank you for you time. Anthony

Kamailio 5.0 - pseudo variable name cleanup
by Sven Neuhaus 07 Mar '16

07 Mar '16

Hi, a suggestion for Kamailio 5.0 is to get rid of the cryptic, case sensitive pseudo-variable names. Instead we replace them with descriptive names like the ones already provided by the TLS module. The current pseudo variables are a constant nuisance unless you deal with Kamailio every day and know them all by heart. They are an unnecessary barrier for new users learning Kamailio and force you to refer to the documentation more often than necessary. Ideally there would be a script to replace old variable names in configuration files with the new ones to make the transition less painful. -Sven

How to get Authorization Attributes
by Matthew Harrold 07 Mar '16

07 Mar '16

Hi All, I am trying to get attributes from the Proxy-Authenticate WWW-Authenticate and Authorization headers, namely username, realm, uri, nonce, and response, I can see some of these are already presented as psuedo-variables, however nonce and response are not. What's the most efficient way to obtain these headers? I'm currently using a regex, but there must be a more efficient method. Thanks for your help, Matthew

Re: [SR-Users] KAMAILIO Installation Problem
by Ed Todd 05 Mar '16

05 Mar '16

KAMAILIO Installation Problem Fred: re confusion. A few more details. Site 1 is a development site. The project in question is VoIP, using ANTISIP. A Windows server application is monitoring activities and carrying out local functions via IPhones. It has a LAN with static IPs for: · Windows 10 PC used for development · Windows 10 laptop, used for testing · MACBOOK, used for IPhone development · ‘Other PC’, recently converted to Linux + KAMailIO, using the binaries installation route rather than the source code route. It has a Comcast Modem/Router, Cisco DPC3941B Site 2 is a business site, which demonstrates the application using its own Windows PC and IPhones. It does not have any static IPs. Each site uses IPhones as the user interface of this application, via cell or WIFI. Both sites can communicate via SIP.ANTISIP.COM Site 1 can communicate with site 1 KAMAILIO but site 2 cannot: timeouts occur. I just installed what seems like a standard package: · Debian 32 or 64 bit graphical · Apt-get install git gcc make flex bison mysql-server kamailio-mysql-modules kamailio-tls-modules kamailio Should be OK so far apart from the .COM name of the Linux box. I then updated files as described earlier and the problems start. Apart from changing a few constants, I have not altered any script, I am just using the standard one shipped in the package above. I’ve had to guess how to tell KAMailIO about the static IP.

KAMAILIO Installation Problem

I have a local area network with: · A Windows PC with a VOIP application · A Linux PC with KAMailIO There is also a remote Windows PC with the same VOIP application. There is also an IPhone VOIP application that communicates with the Windows PC application. All communications use the same KAMailIO system. The IPhone application communicates with the PC on the local network. It times out trying to communicate. I have tried a URL and a static IP address for SIP_DOMAIN, neither succeeds.

DMQ question
by Alex Balashov 04 Mar '16

Hi, If I understand the DMQ documentation correctly, when a SIP request is distributed to other Kamailio instances via dmq_t_replicate(), it is not merely sent as a payload in a novel way, but actually "rehydrated" by the receiver into a mock request on the other end and processed as through it were a "real" message that came into the request_route[] in the natural way. Is this an accurate assumption? -- Alex -- Alex Balashov | Principal | Evariste Systems LLC 303 Perimeter Center North, Suite 300 Atlanta, GA 30346 United States Tel: +1-800-250-5920 (toll-free) / +1-678-954-0671 (direct) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/

options_reply() - ruri contains username
by Alex Balashov 04 Mar '16

04 Mar '16

Hello, This may have been discussed before, but when options_reply() from the siputils module is used to respond to OPTIONS requests and those OPTIONS requests come in with an RURI containing a user part, the following error is emitted to the logs: LM_ERR("ruri contains username\n"); No reply for the OPTIONS ping is given in this scenario. OPTIONS pings against a username are very common, and I can find no justification for this check in my interpretation of RFC 3261 scripture. According to Section 11.1 ("Construction of an OPTIONS request"): An OPTIONS request is constructed using the standard rules for a SIP request as discussed in Section 8.1.1. Moreover, the example request line given in that very section is: OPTIONS sip:carol@chicago.com SIP/2.0 Might it perhaps be agreeable to remove this constraint? Or is there some rationale for its presence that I have simply failed to grasp? Thanks! -- Alex -- Alex Balashov | Principal | Evariste Systems LLC 303 Perimeter Center North, Suite 300 Atlanta, GA 30346 United States Tel: +1-800-250-5920 (toll-free) / +1-678-954-0671 (direct) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/

Hello I am having problems pointing to a custom dispatcher table

Hello I am having problems pointing to a custom dispatcher table, when I use "dispatcher" as table, the kamailio service start running normal, but when I try to use for example "my_dispatcher" table the error shown bellow appears. I do not want to rebuilt the database, *my purpose is to have multiples dispatcher tables on the same server*, "dispatcher, my_dispatcher", "my_dispatcher_1", for example. The connection to the custom database is OK Thanks in advance for your help. ---------------------------------------------------------------------------------------- /var/log/messages Mar 3 14:03:00 kama-balance4 /usr/local/kamailio/sbin/kamailio[19153]: ERROR: dispatcher [dispatch.c:676]: init_ds_db(): invalid table version (found 0 , required 1, 2, 3 or 4)#012(use kamdbctl reinit) Mar 3 14:03:00 kama-balance4 /usr/local/kamailio/sbin/kamailio[19153]: ERROR: dispatcher [dispatcher.c:335]: mod_init(): could not initiate a connect to the database Mar 3 14:03:00 kama-balance4 /usr/local/kamailio/sbin/kamailio[19153]: ERROR: <core> [sr_module.c:970]: init_mod(): init_mod(): Error while initializing module dispatcher (/usr/local/kamailio/lib64/kamailio/modules/dispatcher.so)

mariadb and sql_query_async: the db driver module doesn't support async query
by Daniel Tryba 03 Mar '16

03 Mar '16

So trying to push some inserts/updates to the background I added: async_workers=1 and replaced sql_xquery("ca", "$var(query)", "ra"); sql_result_free("ra"); with sql_query_async("ca", "$var(query)"); where: $var(query)="insert into CDR.callogs (accountcode,number) values ('"+$var(accountcode)+"',substring('"+$rU+"',1,4))"; Only to find out that the queries aren't inserted and the log contains: /usr/sbin/kamailio[24754]: ERROR: sqlops [sql_api.c:429]: sql_do_query_async(): the db driver module doesn't support async query The table is an InnoDB some insert delayed should give these kind of errors, but isn't the point of sql_query_async that it does the plain normal insert in a background task?

Kamailio 5.0 - db_cluster module sql_query_async support
by Daniel Tryba 03 Mar '16

03 Mar '16

If the backends for a dbcluster supports sql_query_async, sql_query_async should be available. At this moment (only tested with 4.3.x) async isn't supported.

Kamailio 5.0 - HTTP loading of config files
by Tim Chubb 03 Mar '16

03 Mar '16

As a suggestion for 5.0 being able to load config files from a URL, with any includes being taken relative to the URL would be a really handy feature. It would allow a central source for config files in a cluster and make it a much simpler process to push out changes to routing to all nodes.

Kamailio as a front-end proxy
by Anton Tonev 02 Mar '16

02 Mar '16

Hello everybody, I am a new user of Kamailio (4.3.1), I am working with it since 1-2 months. The thing that I'm trying to do is to build the following system: same LAN 192.168.0.1 Alice proprietary SIP Server [Public_IP_X] ------------ [Public_IP_Y] Kamailio [172.26.0.1] ---------- [172.26.0.1] with 192.168.0.1 registrar Bob Obviously Kamailio has to translate the local addresses of Alice and Bob, e.g. to use the Nathelper module. The module is doing well its job because the Contact headers are replaced with the Public_IP_X when a REGISTER message is sent by Alice's or Bob's sip phones (I am using Linphone and Zoiper as clients). Once the incoming sip register was treated by Kamailio it is sent to the proprietary SIP Server. The server sends 200 OK to Kamailio and the proxy relays the message to the clients. So the sip registration for me it is OK. But when it comes to initiate a call from Alice to Bob the things are not as I expect it. The initial request INVITE sent from Alice goes to the sip server but then the server instead of sending the INVITE for Bob through Kamailio, it sends the message directly to Bob's device. Does anyone knows how to "tell" to the sip server, using the SIP protocol, that it must use the proxy? The only thing I have in mind is to force Kamailio to replace the contact of Alice and more precisely the host/ip address by the proxy's host/ip address. I tested this idea and the sip server did what I was expecting but for me this is not a proper solution. To do that I used this discussion - http://opensips.org/pipermail/users/2010-October/014873.html Thank you in advance for your attention ! Best regards, Anton

Fwd: [kamailio]: Querie on ratelimit module
by Prashant Desai 02 Mar '16

02 Mar '16

Hi Kamailio, We are using Kamailio V4.2.3 for our project and we are trying to address the performance requirement. We have following queries and need some inputs from Kamailio. *Requirement :* CPU Utilization Limit to 70%, If the limit is crossed Kamailio has to reject the Request. And If it is within the limit Kamailio has to Process the Requests. (i.e. Kamailio has to dynamically set and reset the policy based on CPU Load). *Our Findings* : We have come across ratelimit module in Kamailio, we tried using the same to address the requirement but we see it is not dynamically setting and resetting the policy (once if it starts rejecting then every time it rejects it, only if we restart the kamailo it works) *What we Need*: We need to know 1. Are we using the right module to address the above requirement ? 2. We are only using ratelimit, module, do we have to include any other module along with ratelimit? 3. We are using FEEDBACK algorithm, is that OK ? 4. Setting “ modparam("ratelimit", "pipe", "3:FEEDBACK:70") “ , is this correct ? 5. In ratelimit.c , function static int pipe_push(struct sip_msg * msg, int id) { *case* *PIPE_ALGO_FEEDBACK*: *LM_DBG(**"drop_rate [%d],hash[*pipes[id].counter][%d]\n"**,*drop_rate, hash[*pipes[id].* *counter**])*; ret = (hash[*pipes[id].counter % 100] < *drop_rate) ? -1 : 1; } We are not able to understand the above line ( hash[*pipes[id].counter % 100]). Could you please elaborate. 6. Where are we lagging ?

RFC: Kamailio 5.0
by Daniel-Constantin Mierla 01 Mar '16

01 Mar '16

Hello, at Fosdem and other events this year, while meeting many of Kamailio devs, the topic of what's next for Kamailio came into discussions, with suggestions that after 4.4 it may be time for some major leap to 5.0. I created a page where I collected the main ideas put on table so far - rather unpolished draft, but eventually a good starting point: * https://www.kamailio.org/wiki/devel/kamailio-5.0-design Everyone is invited to add suggestions to the wiki page and/or discuss here on mailing lists, what should be there in 5.0, what is good (to keep) or bad (to remove) with current version, what is missing and it is "must have", ... Not to have a single long tread, for each new idea, start a new email thread with subject prefixed by Kamailio 5.0. I think this impacts users, not only devs, and their contribution is useful as well, so it should be fine to discuss the ideas/concepts on sr-users. When it gets to real implementation discussions, then it can be on sr-dev.

catching lost websocket ua
by Juha Heinanen 01 Mar '16

01 Mar '16

I have done some more digging on websocket:closed event route. In DB_ONLY mode, easy deregistration of a websocket UA at connection close would require access in the event route to connection_id of the closed connection. The function that is run at the close has ws_connection_t argument: static void wsconn_run_route(ws_connection_t *wsc) ws_connection_t record has these two fields: int id; /* id and id_hash are identical to the values */ unsigned id_hash; /* for the corresponding TCP/TLS connection */ Is id the same thing as what is stored in connection_id field of location table? If it is, may be its value could be made available to the event route in a pseudo variable. -- Juha

Hello, We have detected a problem on the increment of CSeq in the SIP header from kamailio. In a session SIP subscribe / notify, we notice that there is a notify that has the same CSeq than the last. As an attachment capture wireshard to clarify our remarks. Is that you can check where is the problem? Best regards.

Help
by Kevin Farrell-Pelletier 29 Feb '16

29 Feb '16

Hi, I work for a VOIP service provider, and have been tasked with optimizing our infrastructure. We have been providing VOIP services to our clients via Asterisk VMs (PIAF) in an ESXi environment, hosted in a datacenter. We are looking for some kind of SIP Router, which would authenticate clients and route their SIP traffic to the appropriate server. By doing so, we are hoping to further secure our infrastructure and to possibly have only one Public IP (which would resolve to the Private IP of the SIP router). The Asterisk servers serve IVR/RINGGROUPS/OUTBOUNDTRUNKS/INBOUNDROUTES/OUTBOUNDROUTES. The Sip Router would therefore route all SIP traffic between the phones and the Asterisk servers, ad the phones would register to the SIP Router. I have tried many solutions (Kamailio, OpenSER, siproxd, Brekeke), but have not been able to configure these services to work the way we want them to. I am including a chart along with this email to outline what we would like to accomplish. Any suggestions or guides would be immensely appreciated. Thank you all for your time.

What is the meaning of "shmized"

Hi, Sorry, but I just want to know the meaning of "shmized", I can't find it in the dictionary, thank you very much. typedef struct _cfg_group { int num; /*!< number of variables within the group */ cfg_mapping_t *mapping; /*!< describes the mapping betweeen the cfg variable definition and the memory block */ char *vars; /*!< pointer to the memory block where the values are stored -- used only before the config is shmized. */ -- Best Regards, Shengy

want to go mobile, common issues ?
by Sébastien Brice 27 Feb '16

27 Feb '16

Hi everyone. I have enjoyed talk about realtime of last FOSDEM, talk about K. was good. I want to know how do you solve sip dialogs with mobile? actually I know REGISTER is important to authenticate and this request generally last 1hour until then you have to register again. How to solve that for mobile telephony (and what about idle) ? do cellular phone use this schema ? you have to go UDP ? does TCP comes better to handle mobile telephony? I want to ask about IMS as well :-) I heard many good things about Image Multimedia Systems, but in concrete terms what is it? Does IMS target mobile only ? i heard about Boghe, it has many more parameters regarding DNS SRV and extra options. What's so different from my traditionnal Linphone ? thx you

ims_qos module support IPv6 address?
by Ayon Pal 26 Feb '16

26 Feb '16

Hi, I have been recently configuring kamailio IMS (v 4.3.4) for IPv6 user registration. I have my PCSCF Gm interface, ICSCF Mw interface and SCSF Mw interface all listening on IPv6 address on port 5060. PCSCF Rx interface is configured with IPv4 address to communicate with PCRF. Similarly ICSCF and SCSCF are also configured with IPv4 address to communicate with HSS (not Fraunhofer HSS) . My Linphone client configured with IPv6 address is sending register message to PCSCF. PCSCF throws the following error on while sending the AAR to PCRF *ubuntu kamailio[22627]: INFO: <script>: REGISTER (sip:001010000000004@TestNetwork (5555:0:0:1:ABCD:0:0:1:9060) to sip:001010000000004@TestNetwork, KFEtBsO-dm)ubuntu kamailio[22627]: ERROR: ims_qos [rx_aar.c:878]: rx_send_aar_register(): Unable to add framed IP AVPubuntu kamailio[22627]: ERROR: ims_qos [rx_aar.c:904]: rx_send_aar_register(): unexpected errorubuntu kamailio[22627]: ERROR: ims_qos [mod.c:1145]: w_rx_aar_register(): Failed to send AARubuntu kamailio[22627]: ERROR: ims_qos [mod.c:1189]: w_rx_aar_register(): Error trying to send AARubuntu kamailio[22627]: WARNING: tm [t_lookup.c:1476]: t_unref(): WARNING: script writer didn't release transaction* On debugging, I found that the ip version is hard coded to AF_INET.( a comment is also written TODO: IPV6 support) in ims_qos/mod.c file. On changing it to AF_INET6 ( I did this 'cos I saw IPv6 based checking on other files like "ims_qos/rx_avp.c") I can see AAR from PCSCF to PCRF, but Framed IPv6 Prefix AVP is incorrect. So, I would like to know if ims_qos module supports IPv6 address ? Regards, Ayon

Media server can't return ACK correctly
by Alexandru Covalschi 26 Feb '16

26 Feb '16

Hello everyone. The setup is: Carrier ip is CARRIER_IP Public network Kamailio IP will be PUBLIC_IP Private network Kamailio IP will be KAMAILIO_PRIVATE_IP Private network Freeswitch IP is FREESWITCH_PRIVATE_IP ACK CARRIER_IP -> PUBLIC_IP->FREESWITCH_PRIVATE_IP And freeswitch tries to actually send ACK back to PUBLIC_IP which he can't access. Kamailio trace: http://pastebin.com/raw/1W1sXuUa Freeswitch trace: http://pastebin.com/raw/KkZCwTTJ request_route: http://pastebin.com/raw/Y17pXUGY NATMANAGE route: http://pastebin.com/raw/0BpPDjN0 WITHINDLG route: http://pastebin.com/raw/5LpwSigF I'm seeking help with that - what parameter I need to change/add to solve that? Maybe it's a networking problem - but why then ACK reaches Freeswitch and all other requests flow OK?

[4.2.6] Keep-alive sent by dialog module seems does not refresh the dialog...
by Jack Wang 26 Feb '16

26 Feb '16

Hello, I used the below settings to test the keep-alive function within a dialog: modparam("dialog", "default_timeout", 60) modparam("dialog", "ka_timer", 10) modparam("dialog", "ka_interval", 30) and use dlg_set_property("ka-src") or dlg_set_property("ka-dst") to send OPTIONS to caller or callee. A few questions to ask: (1) What's the difference between ka_timer and ka_interval? I read the http://www.kamailio.org/docs/modules/4.2.x/modules/dialog.html , but still can not understand very clearly. I know the ka_interval means OPTIONS will be sent after 30 seconds when dialog started or last keep-alive has been done. but I don't know how ka_timer works. (2) From the packets captured I can see server sent OPTIONS and the client (caller or callee) sent back 200 OK. According to the document, "The dialog timeout is reset each time a sequential request is processed" However, the dialog was still timeout, it seems that the timeout value was not reset. And I make the clients send the OPTIONS and frequently , the dialog never expires now. So the refresh only works on the keep-alive sent by clients not the server here? Thanks :)

Binary interface: usrloc replications - restore registrations after node restart
by evoip＠ukr.net 25 Feb '16

25 Feb '16

Hi ! It's really nice option - that now Opensips nodes can replicate "SIP registrations" and "Dialogs" between each other w *"bin_listen" options. http://www.opensips.org/Documentation/Interface-Binary-2-1 * I have a few question related to cluster architecture with fail over: 1). - If one of the "Opensips phone edges" was restarted - can it catch all USRLOC registrations throught binary interface from alive nodes ? - if it can't do restoring of the database through binary interface - maybe you have an idea how to do that ? 2). - it's share dialogs information - if one node is suddenly down, can call dialog be proceeded on other node ? With kind regards, Ewgeny Berladin Voip Engineer

how to drop 200ok and survive?
by Uri Shacked 25 Feb '16

25 Feb '16

Hi, for some strange reason, ask my regulator.... i need to manipulate certain calls. the scenario goes like this: 1. caller sends invite to kamailio. 2. kamailio transfer the call to asterisk. 3. asterisk send progress and play "hello". 4. asterisk creates a new call (dial) to the same kamailio with destination callee. 5. the callee answers the call. here, i need to block the 200ok. so that the caller does not receive it. i managed to block it with t_suspend(). but, there is no bidirectional media. the 183 progress was sent with sendreceive. it seems the asterisk is waiting for the ACK in order to open both ways for media. i tried to use uac_send_req() but it is being sent with no to tag. and when i try manipulating the uac_req(turi) it does not help because it takes all the string i entered and wraps it with <>. any ideas? BR, Uri

Credential server
by Marek Moravčík 25 Feb '16

25 Feb '16

Hi guys, I am currently doing research in SIP security. As described in RFC 6072, there can be credential server storing public and private keys (certificates). I have question, if there is any support from Kamailio for this, or if somebody has tried similar things with Kamailio. Thanks! Best regards Marek Moravcik

Can not start kamailio 4.3 and 4.4. Fork errors with working configuration.
by Yuriy Gorlichenko 25 Feb '16

25 Feb '16

Checked config at another servers instanses. I tried to start 2 workable configs. All starts ends with 3 type of errors error.log error2.log error3.log Debug outputs of 3 times started one config on one same server. I think error outside kamailio because 4.3 and 4.4 also compiled successfully. But at this time I can not understand where is trouble. In first file I see that kamailio can not connect to database but user/pass is correct, and I also see that kamailio can not make fork of process. 2 and 3 process have different troubles but base is one - can not fork.

ovh trunk
by Sébastien Brice 24 Feb '16

24 Feb '16

Hi everyone I followed this guide http://kb.asipto.com/asterisk:realtime:kamailio-4.0.x-asterisk-11.3.0-astdb and got it working (101, 102 and 103) can call eachother. But now i am trying to figure Asterisk's role out. I am more an ipbx person and i am used to register providers trunk in asterisk/sip.conf file, like this: register => [peer?][transport://]user[@domain][:secret[:authuser]]@host[:port][/extension] doing that i got plenty of OPTIONS request and 200 OK reply between my Kamailio and my provider (and it is a bit noisy) doing that i feel missing kamailio's logic and power to deal with externals trunk provider The thing is i need my authenticated users (101,102,103) be capable dialing my trunk and requesting INVITE for non-local request. What is the best way to achieve that? My DID provider gave me user/passwd/realm. I heard about avp special variables (auth_XXXX_avp and uac) and some snippets config that could help me to go there. Is that efficient to place the routing's logic to Kamailio and how to do that with my ovh trunk? thx you
