kamailio 4.4 registering to a SIP trunk provider using UAC then outbound routing to it.
by Jonathan Hunter 13 Sep '17

13 Sep '17

Hi Guys, I have a SIP provider who only accept registrations from users, so I have registered my kamailio Server with them using the uac module. It is registered fine, and I can get inbound calls on the trunk. My query is the best way to send outbound calls out via the registered sip gateway? I would normally load balance using dispatcher if it was to IP authenticating providers, but as they are using registration, what would be best practice to send outbound calls via the registration which is establised with the uac module? Is it just a question of doing it within the configuration file, as again they will look to auth requests as well with a 401/407 so I assume I can use uac_auth() for that. Just wondering what other people have done if anything, is my other option is to register using a B2Bua on the same server, and leave kamailio just as a proxy. Many thanks Jon

Hello.

But that don't happen. I don't see any OPTIONS messages in sngrep in established calls. What's wrong? I call dlg_manage() right before main t_relay, everything including CDRs are working fine...

Can not register on kamailio
by Adesh Pandey 13 Sep '17

13 Sep '17

I am new to kamailio and I want to setup Kamailio as dispatcher for two Asterisk boxes but SIP registrations must be happening on the Kamailio itself. I have enabled mysql module and used auth module but when I try to register it says unauthorized access. In subscribers list I have added an entry for sip user 1 with domain as kamailio IP. Please help me to understand where can I improve so that I can implement register on Kamailio. -- Adesh Pandey Sr. Software Developer [image: phone] +91 92129 92129 Ext: 56 [image: moible] +91 8527384897 [image: Profile Pic] [image: Facebook] <https://www.facebook.com/VoiceTree?_rdr>[image: Twitter] <https://twitter.com/MyOperator>[image: Twitter] <https://www.youtube.com/user/MyOperatorCo>[image: Linkedin] <https://www.linkedin.com/company/voicetree-technologies>[image: Google+] <https://plus.google.com/+MyoperatorCo/posts> [image: Logo] <http://myoperator.co/>

Problem implementing usrloc via dmq
by Aleksandar Sosic 13 Sep '17

13 Sep '17

Hi everyone, we're trying to make work usrloc over dmq without a db on our nodes. Our `kamailio.cfg` code to make it work on the nodes is like this: ``` ... loadmodule "usrloc.so" ... loadmodule "dmq.so" loadmodule "dmq_usrloc.so" ... modparam("dmq", "server_address", DMQ_ADDRESS) modparam("dmq", "notification_address", "sip:routers.ourcloud.com:5060") modparam("dmq", "multi_notify", 1) modparam("dmq", "num_workers", 4) modparam("dmq_usrloc", "enable", 1) modparam("dmq_usrloc", "sync", 1) ``` Where `DMQ_ADDRESS="sip:<some_address>:5060"` is the public IP address of the running node. `nslookup` of `routers.ourcloud.com`: ```➜ ~ nslookup routers.ourcloud.com Server: 8.8.8.8 Address: 8.8.8.8#53 Non-authoritative answer: Name: rrouters.ourcloud.com Address: <IP1> Name: routers.ourcloud.com Address: <IP2> ``` and obviously IP1 and IP2 are pubblic IPs of kamailio nodes that respond to my pings. When i register a client to node IP1 it's ul dump is: ``` { "jsonrpc": "2.0", "result": { "Domain": "location", "Size": 1024, "AoRs": [{ "Info": { "AoR": "0409828030", "HashID": 1970914268, "Contacts": [{ "Contact": { "Address": "sip:0409828030@172.19.0.255:56328;ob", "Expires": 289, "Q": -1, "Call-ID": "5mclwiX4oYAVK0z-iT7M0p9RBX5-02g6", "CSeq": 59427, "User-Agent": "Telephone 1.2.6", "Received": "sip:<PROXY_IP>:5060", "Path": "[not set]", "State": "CS_NEW", "Flags": 0, "CFlags": 192, "Socket": "udp:<IP1>:5060", "Methods": 8159, "Ruid": "uloc-599d8fa8-f-1", "Instance": "[not set]", "Reg-Id": 0, "Last-Keepalive": 1503498176, "Last-Modified": 1503498176 } }] } }], "Stats": { "Records": 1, "Max-Slots": 1 } }, "id": 1 } ``` On node with IP2 the ul dump is: ``` { "jsonrpc": "2.0", "result": { "Domain": "location", "Size": 1024, "AoRs": [], "Stats": { "Records": 0, "Max-Slots": 0 } }, "id": 1 } ``` What are we doing wrong?

Q: purpose of t_newtran() in kamailio-basic.cfg route[LOCATION]?
by Anthony Alba 09 Sep '17

09 Sep '17

In kamailio-basic.cfg route[LOCATION] we have the following: --snip-- $var(rc) = $rc; t_newtran(); switch ($var(rc)) { case -1: case -3: --snip-- What is the purpose of t_newtran() here? Since we have not hit t_relay() yet (and don't have a transaction) is this to ensure the caller sees/acks the 404/405? Earlier in the mailing list https://lists.kamailio.org/pipermail/sr-users/2015-April/088062.html I read, although this is in reply to a different situation: "Why do you need to create new transactions yourself with t_newtran()? Nonexotic applications of Kamailio usually don't require this. ..." # User location service route[LOCATION] { if (!lookup("location")) { $var(rc) = $rc; t_newtran(); switch ($var(rc)) { case -1: case -3: send_reply("404", "Not Found"); exit; case -2: send_reply("405", "Method Not Allowed"); exit; } } # when routing via usrloc, log the missed calls also if (is_method("INVITE")) { setflag(FLT_ACCMISSED); } route(RELAY); exit; } Thanks AAlba

It crashes after several calls when wait_timer fires. #0 0xb74a8556 in raise () from /lib/libc.so.6 #1 0xb74a9d78 in abort () from /lib/libc.so.6 #2 0x08293ae2 in qm_free (qmp=0xad65d000, p=0x3d64692d, file=0xb6216a16 "tm: h_table.c", func=0xb621663c <__FUNCTION__.18751> "free_cell_helper", line=187, mname=0xb621664d "tm") at core/mem/q_malloc.c:471 #3 0xb613f103 in free_cell_helper (dead_cell=0xae2cd210, silent=0, fname=0xb6239ea5 "timer.c", fline=655) at h_table.c:187 #4 0xb61e7758 in wait_handler (ti=557858937, wait_tl=0xae2cd258, data=0xae2cd210) at timer.c:655 #5 0x0826a2cc in timer_list_expire (t=557858937, h=0xad6b9668, slow_l=0xad6ba144, slow_mark=312) at core/timer.c:874 #6 0x08267cb1 in timer_handler () at core/timer.c:939 #7 0x0826a4d3 in timer_main () at core/timer.c:978 #8 0x08069575 in main_loop () at main.c:1721 #9 0x080707ca in main (argc=11, argv=0xbf85f044) at main.c:2723 When crash happens, kamailio prints the following message: Sep 4 16:15:38 [18938]: : <core> [core/mem/q_malloc.c:469]: qm_free(): BUG: qm_free: bad pointer 0x70707553 (out of memory block!) called from tm: h_table.c: free_cell_helper(187) - aborting Also had a few crashes in retransmission_handler(): #0 0xb750b556 in raise () from /lib/libc.so.6 #1 0xb750cd78 in abort () from /lib/libc.so.6 #2 0xb6249b5a in retransmission_handler (r_buf=0xae036674) at timer.c:367 #3 0xb6247558 in retr_buf_handler (ticks=1234464444, tl=0xae036688, p=0x1f40) at timer.c:594 #4 0x0826a2cc in timer_list_expire (t=1234464444, h=0xad71c668, slow_l=0xad71cd44, slow_mark=2232) at core/timer.c:874 #5 0x08267cb1 in timer_handler () at core/timer.c:939 #6 0x0826a4d3 in timer_main () at core/timer.c:978 #7 0x08069575 in main_loop () at main.c:1721 #8 0x080707ca in main (argc=11, argv=0xbff64134) at main.c:2723 ERROR: tm [timer.c:366]: retransmission_handler(): transaction 0xae0365e0 scheduled for deletion and called from RETR timer (flags 6d) Both timers fired for an INVITE transaction that was previously suspended by async_route(), then resumed, sent out and received a 4xx reply (407). This configuration worked fine with kamailio 4.2.x and problem appeared after upgrading to 5.0.2. Trying to figure out how to narrow down the problem. Any input is appreciated.

handle_tcpconn_ev(): connect failed
by Donat Zenichev 07 Sep '17

07 Sep '17

Hi. Recently I've come across with TCP connection problem. The topology is as following: DNS srv load balancer - two kamailio proxy servers - one routing server. Client appeals to NAPTR record like: sip.domain.com So dns returns one of the proxy servers to client (depending on weight/priority). Now both kamailio have the same priority and weight (the goal is load balancing). Routing server (now it is asterisk) working with chan_pjsip.so, that supports NAPTR/SRV records. He is able to resolve Record-Route / Route headers with value - sip.domain.com (that proxy servers add to record-route headers while relaying requests to him). This topology is done to support present dialogs, even if proxy that recently processed it, is dead. But the problem comes, when routing server (asterisk) sends in-dialog requests to the proxy, that wasn't used to establish the dialog. Example, routing server obtains 200 OK from endpoint (relayed by kamailio1 to him) and he sends back ACK, but not to the kamailio1, he sends it to kamailio2 (because he resolves NAPTR sip.domain.com and gets ip of second kamailio). Kamailio2 processes the request as usual, because both kamailio have the same db for dialog module, but when he tries to relay the request to endpoint, he gots the error: ERROR: <core> [tcp_main.c:4070]: handle_tcpconn_ev(): connect XXX.XXX.XXX.XXX:52185 failed The port that kamailio2 tries to use to relay the ACK, is port that endpoint used to establish the dialog with kamailio1 and actually his TCP connection is now established with kamailio1. So kamailio2 tries to use the same port and gets the error. And this is proper behavior I think. There is no problem with UDP transport. Has anyone seen the similar problem? That indeed is not a problem, but proper behavior. -- -- BR, Donat Zenichev Wnet VoIP team Tel: +380(44) 5-900-808 http://wnet.ua

cr failure routes
by Nelson Migliaro 07 Sep '17

Hello, I am using carrierroute in Kamailio (great module btw). All calls go the same gateway (rewrite_host). I am routing over differents vendor using a prefix. Prefix: 21 dnis: 999999999 $rU after rewrite_host is 21999999999 My problem is when trying to use a failure route, next domain use a different prefix but the host. So I get the: Candidate destination <gateway> was previously used Is there a flag or something to prevent this verification ? Thank you Nelson.-

Call pickup with feature code
by Cyrille Demaret 06 Sep '17

06 Sep '17

Hi, I'm trying to implement call pickup with a feature code for phones that doesn't support "Replaces" header. User has to dial for example *8 to pickup a call who is in the same group pickup. My idea is to loop for each members of the group (coming from a SQL table using sqlops) and check for calls in early state. I was thinking to use the dialog module to search for active calls but I don't find any function allowing to do this. Does anyone know a module with a function allowing to find an active calls by callee? Thank you, Cyrille

SQL for ordered LCR rules
by Patrick Wakano 06 Sep '17

06 Sep '17

Hello list, Hope you all doing well! I am trying to ease the management of LCR routing rules, since once we begin to have multiple prefixes, multiple GWs and so on, the visualization and management of the rules priorities becomes exponentially hard to do. So first thing I am trying to achieve is an easy way of retrieving the rules in an ordered manner. I couldn't find any tool to do such thing and source code was not very friendly.... so I've come up with this Postgresql query that I think retrieves all rules in the same order I expect LCR to select the GWs. SELECT lr.lcr_id, lr.prefix, lrt.priority, lg.gw_name, lg.ip_addr FROM lcr_rule lr JOIN lcr_rule_target lrt ON lrt.lcr_id = lr.lcr_id AND lrt.rule_id = lr.id JOIN lcr_gw lg ON lg.lcr_id = lr.lcr_id AND lg.id = lrt.gw_id WHERE lr.enabled = 1 AND lg.defunct = 0 AND lr.lcr_id = ID AND lr.prefix SIMILAR TO '(|PREFIX%)' ORDER BY lr.lcr_id, LENGTH(lr.prefix) DESC, lrt.priority; It is missing the weights calculation, but it is rather complex and I am not using it anyway.... Other than that does anyone did something similar to check if my query really matches what LCR engine does? Thanks, Patrick Wakano

Re: [SR-Users] SQL for ordered LCR rules
by Patrick Wakano 06 Sep '17

06 Sep '17

Thanks for the response guys! The link https://github.com/dimitri/prefixIt is returning 404.... Regarding the performance itself I am not worried since this select it is just for management and I don't expect having millions of rules. The idea is just to have an easy way to have a picture of how the LCR will order and select the gateways based on a given prefix. The three LCR tables are not so easy to handle and manage from command line so my idea was to have a single SELECT or VIEW to return me all I need at once! >From what I could check, I think the select I sent pretty much translates what LCR module does internally, I am just trying to verify if it has some flaw, which could mislead me in the rules management.

real-time update question
by Stent, Bob 05 Sep '17

05 Sep '17

I am just starting out with Kamailio. One of the things I want to be able to do is add a domain to the configuration and have Kamailio pick it up without having to restart. I see there is a runtime update framework but I am having trouble navigating the documentation to find out what this actually does for me. Can somebody point me to the right set of docs to read to figure this out? Do I simply add an alias to the kamalio.cfg file and somehow send an RPC command to Kamalio to re-read configuration?

Question about fix_nated_contact.
by Володимир Іванець 04 Sep '17

04 Sep '17

Hello everyone, I have system setup where there are few Asterisk servers behind Kamailio that is behind the firewall. There is a problem with call initiation. When phone from outside sends INVITE to Kamailio, it then passes it to one of Asterisk servers. Asterisk server eventually replies to Kamailio with 200 OK. Contact header contains Asterisk's local IP address and port. Kamailio executes function *fix_nated_contact* before sending reply to the phone. However Contact header will still have Asterisk's local socket. *fix_nated_contact* is being executed with no doubt. I can see xlog output that I set before and after it. Can someone tell how exactly *fix_nated_contact* gets "*request's source address:port pair*" and if it can be printed to the log? Thank you!

Homer confusion ....
by Mark Boyce 04 Sep '17

Hi All Trying to get a basic version of homer working on Kamailio V5. So far I have sipcapture throwing everything in to a single mysql table. So first question; Should I be using sipcapture or siptrace? I’m not sure I can see the difference. Second question; On what I have working so far using sipcapture, I’m seeing the invites, subscribes, cancels, act’s all end up in the database. What I’m missing is any responses from Kamailio back to the handset (AUTh Challenges etc) modparam("sipcapture", "db_url", "mysql://sipcapture:secretpassword@localhost/homer_data") modparam("sipcapture", "capture_on", 1) modparam("sipcapture", "hep_capture_on", 1) modparam("sipcapture", "insert_retries", 5) modparam("sipcapture", "insert_retry_timeout", 10) plus a sprinkling of "sip_capture(); “ in the “xxx_route {“ blocks What am I missing?

Hello. Have a following task. Select carrier by carrierroute module from db, try to route (dial, relay, bridge - you name it) call there and if call is failed/rejected due to any reason, go to failure_route(?), perform carrierroute lookup again for another carrier and route call there. Main problem is that different carriers require different From/To format. And Kamailio don't allow to use uac* functions in failure_route. How to resolve this? Maybe entire routing method is wrong for my task? Any advice? -- sent from myMail for Android

Hi Mykyta, since you are plain sip without encryption you can see your sip-traffic on the wire, use sngrep on the kamailio box to figure out whats with the sip-dialogs - it helps a lot. https://github.com/irontec/sngrep and if its more an kamailio config problem, it would be better to stay at sr-users@.

I have a problem that call drops after 32 seconds with error ACK Timeout. kamailio.cfg - https://pastebin.com/x0CL3TEZ kamailio sip messages log - https://pastebin.com/wyT3cBbD freeswitch logs with sip debug - https://pastebin.com/zPysfQkV I'm struggling for a week and have no idea how to fix it. Thank you very much. Mykyta Nikitenko

Change on the fly logging verbosity - Kamailio v5.0.2
by Karsten Horsmann 01 Sep '17

01 Sep '17

Hello, at this moment i try to figure out the best way to add an "switch" for debug/log output. I use many xlog, like everyone that starts with kamailio too. Then i go further and add #!ifdef cases around to switch this via #!define. Is there any other way to turn on/off my "debug"-logging on the fly, while kamailio is still running? #!define TESTBED_MODE request_route{ ... #!ifdef TESTBED_MODE route(DEBUG); #!endif ... #!ifdef TESTBED_MODE xlog("L_INFO","---FIX_SIPS-after: ru:($ru)"); #!endif ... } -- Kind Regards *Karsten Horsmann*

Kamailio SIP protocol over WSS
by Washington Costa 31 Aug '17

31 Aug '17

Hi. I'm trying use the JSSIP cliente and Kamailio with WSS. On these sites I generated my certificates: https://letsencrypt.org/ and https://certbot.eff.org/ My browser identify the certificates but SIP client just say: failed: WebSocket opening handshake was canceled Do you have any idea how to fix it? Do you can say a checklist with everything I need to do for use Kamailio with WSS? Here is my log on Kamailio: Aug 31 09:10:10 ip-172-31-39-220 kamailio[13183]: 33(13239) DEBUG: <core> [core/ip_addr.c:229]: print_ip(): tcpconn_new: new tcp connection: 187.41.60.10 Aug 31 09:10:10 ip-172-31-39-220 kamailio[13183]: 33(13239) DEBUG: <core> [core/tcp_main.c:985]: tcpconn_new(): on port 44630, type 3 Aug 31 09:10:10 ip-172-31-39-220 kamailio[13183]: 33(13239) DEBUG: <core> [core/tcp_main.c:1291]: tcpconn_add(): hashes: 3062:1194:1491, 2 Aug 31 09:10:10 ip-172-31-39-220 kamailio[13183]: 33(13239) DEBUG: <core> [core/io_wait.h:380]: io_watch_add(): DBG: io_watch_add(0xa4ac60, 53, 2, 0x7f259df9cd80), fd_no=44 Aug 31 09:10:10 ip-172-31-39-220 kamailio[13183]: 33(13239) DEBUG: <core> [core/io_wait.h:602]: io_watch_del(): DBG: io_watch_del (0xa4ac60, 53, -1, 0x0) fd_no=45 called Aug 31 09:10:10 ip-172-31-39-220 kamailio[13183]: 33(13239) DEBUG: <core> [core/tcp_main.c:4139]: handle_tcpconn_ev(): sending to child, events 1 Aug 31 09:10:10 ip-172-31-39-220 kamailio[13183]: 33(13239) DEBUG: <core> [core/tcp_main.c:3818]: send2child(): selected tcp worker 1 26(13225) for activity on [tls:172.31.39.220:4443], 0x7f259df9cd80 Aug 31 09:10:10 ip-172-31-39-220 kamailio[13183]: 26(13225) DEBUG: <core> [core/tcp_read.c:1574]: handle_io(): received n=8 con=0x7f259df9cd80, fd=9 Aug 31 09:10:10 ip-172-31-39-220 kamailio[13183]: 26(13225) DEBUG: tls [tls_server.c:197]: tls_complete_init(): completing tls connection initialization Aug 31 09:10:10 ip-172-31-39-220 kamailio[13183]: 26(13225) DEBUG: tls [tls_server.c:226]: tls_complete_init(): Using initial TLS domain TLSs<default> (dom 0x7f259ddc4a80 ctx 0x7f259de03bc0 sn []) Aug 31 09:10:10 ip-172-31-39-220 kamailio[13183]: 26(13225) DEBUG: tls [tls_domain.c:715]: sr_ssl_ctx_info_callback(): SSL handshake started Aug 31 09:10:10 ip-172-31-39-220 kamailio[13183]: 26(13225) DEBUG: <core> [core/tcp_main.c:2430]: tcpconn_do_send(): sending...

question for best way to remove sips uris - TLS and sips in $ru - get_send_socket2(): protocol/port mismatch
by Karsten Horsmann 31 Aug '17

31 Aug '17

Hello List, of course - best way is not to use sips: uri scheme. But i have to deal with that. I try to configure an multihomed kamailio (public/private IP) in front of my SIP-Servers. One of my softphones variants used TLS for connection but the INVITES of this softphone use the "sips" URI scheme. As i saw in other posts, this seems to be an issue for many people. In my case it breaks the routing to my internal sip-server (only plain udp). Most of my config is similar to havfos example + TLS. https://github.com/havfo/WEBRTC-to-SIP/blob/master/etc/kamailio/kamailio.cfg I tried to fixed that with this extra route - but this breaks the dialog somewhere - after 60 seconds i have no audio and the BYE becomes another CSeq: in the request_route right after route(AUTH) i add my route(FIX_SIPS) if (is_method("INVITE|SUBSCRIBE")) { if ($ru =~ "^sips:") { route(FIX_SIPS); } else { record_route(); } } route[FIX_SIPS] { if ($ru =~ "^sips:") { xlog("L_INFO","---FIX_SIPS-before: ru:($ru)"); $var(orig_uri) = $ru; $ru = "sip:" + $rU + "@" + $td; xlog("L_INFO","---FIX_SIPS-now: $rU $td ru:($ru) orig_uri:($var(orig_uri))"); record_route(); #$ru = $var(orig_uri); xlog("L_INFO","---FIX_SIPS-after: ru:($ru)"); } } 172.20.120.81 = Kamailio private IP 172.20.120.79 = My internal SIP-Server (B2BUA) I used kamailio with CentOS 7 and RTPENGINE 63bdd615 from master kamailio-5.0.2-3.1.x86_64 kamailio-tls-5.0.2-3.1.x86_64 kamailio-mysql-5.0.2-3.1.x86_64 kamailio-websocket-5.0.2-3.1.x86_64 -- Kind Regards *Karsten Horsmann*

kamailio asterisk + provider sip trunks

Good morning! kamailio + dispatcher + provider trunks. How to make RR for incoming calls from pstn? my trunks are authorized on an asterisk, but i have problem with multiple calls on each asterisk. If I do through uac then I have a problem with BYE, and in general the module is uncomfortable. Please tell me how to implement a bunch: kamailio + asterisk + provider trunks..

Kamailio failover - dialog (transaction) that is available on different proxies
by Donat Zenichev 30 Aug '17

30 Aug '17

Hi. I came up with idea to set up stand with two kamailio and one b2bua server (for routing). The idea consists of failover for dialogs, transactions. So if one of kamailio nodes is down, another one is able to catch up the dialog and let users to properly end up the session. For better realizing of it, I will try to describe the idea step by step: 1. UAC invites UAS, they've done three-way-handshake, media stream is up. 2. Kamailio that processed this dialog is down. 3. Users decided to end the session with BYE method, but proxy that processed their three-way-handshake recently is down, so one of ua sends BYE to the destination route that contains domain name (that both kamailio serve), BYE achieves the second kamailio to let him properly end the dialog. But, there is a big but, this second kamailio hasn't ever known about this dialog, he doesn't support any transactions for it and furthermore he doesn't know anything about this call-id. So the solution for it, as I think, is hidden in db mode for user location (columns that contain call-ids, branches etc. But I need to be sure, if I'm on the right way. For purpose, where one ip is served by two nodes, I have two solutions: -First one. I want to create heartbeat cluster with two kamailio nodes, they will have one shared ip address, so when one node gets down, another one brings up shared ip interface and implements the same actions that master does. -Another method is to assign a few ip addresses to one domain name (ip addresses of different kamailio proxies). So the goal looks simple, if someone has ever done something like that, I will be glad to read the ideas. -- -- BR, Donat Zenichev Wnet VoIP team Tel: +380(44) 5-900-808 http://wnet.ua

Fwd: sdp extra \r\n in multipart body
by Diego Nadares 29 Aug '17

29 Aug '17

Hi Daniel! Thanks for your reply. The rtpengine module I think it's expecting two \r\n like: ...pcma/8000\r\n \r\n --uniqueboundary .... cpc,9\r\n \r\n --uniqueboundary-- I saw the code and I modified it but Can any one cofirm if multipart has to be like ...pcma/8000\r\n \r\n --uniqueboundary Or ...pcma/8000\r\n --uniqueboundary Or any one of those?

LCR dont_strip_or_prefix_flag
by Patrick Wakano 29 Aug '17

29 Aug '17

Hello list, I am using Kamailio 5.0.2 on centos7 and I am trying to use the dont_strip_or_prefix_flag ( https://www.kamailio.org/docs/modules/5.0.x/modules/lcr.html#idp49131644) for LCR routing but I discovered that just by declaring the flag like this the module won't prefix my calls: #!define LCR_DONT_STRIP_OR_TAG 7 modparam("lcr", "dont_strip_or_prefix_flag", LCR_DONT_STRIP_OR_TAG) It doesn't matter if I set or reset the flag it never prefix the ReqUR if the declaration is present. I have to remove the declaration to make the module prefix it correctly. But then the whole purpose of the flag is lost....Anyone aware of this behaviour? Regards, Patrick Wakano

TSILO + NAT issues
by Emanuele Gambaro 28 Aug '17

28 Aug '17

Hi to all. I have the following setup-needs : *) Kamailio 5.0.1 with TSILO module and Apple push notification service. *) Rtpengine configured in order to force a "media-handover” for every call. *) NAT forced for all connection. I have a lot of problem with the INVRESUME route. When an INVITE is resumed (upon mobile client connection via APN message) the NAT does not work, and there is no rtp flow between devices. It works only if device is already online (so without the SUSPEND route). How can I setup TSILO in order to force NAT management for all calls? Thank you -- Emanuele Gambaro --- email: emanuele.gambaro(a)pynlab.com skype: sarbyn_work OpenPGP Key: https://goo.gl/fdeVnI

Fwd: Weird issue with kamailio relaying messages to itself
by George Diamantopoulos 26 Aug '17

26 Aug '17

Stupid gmail replying to sender only... ---------- Forwarded message ---------- From: George Diamantopoulos <georgediam(a)gmail.com> Date: 27 August 2017 at 02:29 Subject: Re: [SR-Users] Weird issue with kamailio relaying messages to itself To: Daniel-Constantin Mierla <miconda(a)gmail.com> Hello all, I've figured out what was going on, so I'm sharing here in case anyone else runs into this. I guess it should be a fairly common situation under certain circumstances when using the dispatcher module... The problem was that no destinations in the dispatcher set used were available for these requests. So $du was not set by ds_select_next. Which meant that when t_relay() was called later in the script, it would route based on R-URI, and the RURI's uri was kamailio itself. As to the reason why I was left with no dispatcher destinations available, well, I would mark destinations offline for 500 "server error" responses coming from them, and asterisk (which is the receiving application for all of dispatcher's destination sets) will send out a 500 to the B-leg when it receives a 480 to an A-leg. Getting a single 480 to one of the asterisk boxes would cause this to happen across all destinations, as kamailio would retry the next destination after a 500 failure and would receive a 500 from all of them in the end (because all of them would get the 480 in such small time frame).

Kamailio fails to process ACK to 487 from Cisco-SIPGateway/IOS-12.x?
by George Diamantopoulos 26 Aug '17

26 Aug '17

Hello all, I'm having a weird issue with Kamailio failing to properly process an ACK received to a 487 it sent, resulting in retransmissions of the 487. I assume it's because it can't match the ACK to the transaction, but I could be wrong. I'm using a modified version of the default configuration, so ACKs should be handled correctly. I haven't editted the WITHINDLG route in any way that would affect this (or at least I think). In addition, ACKs to 487 from other UAs are processed correctly, and these transactions are handled by the same routes in kamailio configuration as the problematic one, so I'm inclined to believe it's UA-specific? Here's an example transaction of the failed kind (results in kamailio retransmitting the 487): myself:5060 -> peer:5060 ------------------------- SIP/2.0 487 Request Terminated Via: SIP/2.0/UDP peer:5060 From: <sip:user@peer>;tag=116B5368-24D8 To: <sip:tel@myself>;tag=as655f6372 Call-ID: 84DC69F2-873811E7-8A639B5A-3D9194E8@peer CSeq: 101 INVITE Server: modCOM v2 SIP Server Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY, INFO, PUBLISH, MESSAGE Supported: replaces, timer Content-Length: 0 peer:49590 -> myself:5060 ------------------------- ACK sip:tel@myself:5060 SIP/2.0 Via: SIP/2.0/UDP peer:5060 From: <sip:user@peer>;tag=116B5368-24D8 To: <sip:tel@myself>;tag=as655f6372 Date: Wed, 23 Aug 2017 12:50:47 GMT Call-ID: 84DC69F2-873811E7-8A639B5A-3D9194E8@peer Max-Forwards: 10 Content-Length: 0 CSeq: 101 ACK And here's another similar transaction which is successful (no retransmissions): myself:5060 -> peer:5060 ------------------------ SIP/2.0 487 Request Terminated Via: SIP/2.0/UDP peer:5060;branch=z9hG4bKjbmvq4009gthskk0a6s1.1 From: <sip:user@anonymous.invalid;user=phone>;tag=599D7495-9ACE9E3-0A324A05 To: <sip:tel@anonymous.invalid:5060;user=phone>;tag=as65375e5d Call-ID: 599D7495-007A5832@fath3pcu238 CSeq: 1 INVITE Server: modCOM v2 SIP Server Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY, INFO, PUBLISH, MESSAGE Supported: replaces, timer Content-Length: 0 peer:5060 -> myself:5060 ------------------------ ACK sip:tel@myself:5060;user=phone SIP/2.0 Via: SIP/2.0/UDP peer:5060;branch=z9hG4bKjbmvq4009gthskk0a6s1.1 From: <sip:user@anonymous.invalid;user=phone>;tag=599D7495-9ACE9E3-0A324A05 To: <sip:tel@anonymous.invalid:5060;user=phone>;tag=as65375e5d Call-ID: 599D7495-007A5832@fath3pcu238 Max-Forwards: 69 Content-Length: 0 CSeq: 1 ACK I can't pinpoint anything wrong with the first exchange, other than the fact that for some reason, the "less than" (<) sign in the from and to URIs is escaped as &lt in homer's GUI (which also breaks CSS rendering in Firefox, I had to clear this code out). However, these escaping characters are not visible with sngrep when capturing traffic normally, and neither when doing a select in homer's database directly, so I guess it's a rendering bug in homer-ui and can be ignored (unless someone has reason to believe otherwise). Now the relevant portion of the debug log is: Aug 23 16:47:12 modcom-sbc-1 kamailio[9750]: {1 101 ACK 64AA4E6C-874011E7-9A729B5A-3D9194E8@peer} 7(9760) exec: *** cfgtrace:request_route=[WITHINDLG] c=[/etc/kamailio/kamailio.cfg] l=223 a=24 n=t_check_trans Aug 23 16:47:12 modcom-sbc-1 kamailio[9750]: {1 101 ACK 64AA4E6C-874011E7-9A729B5A-3D9194E8@peer} 7(9760) DEBUG: tm [t_lookup.c:1001]: t_check_msg(): msg id=104 global id=103 T start=(nil) Aug 23 16:47:12 modcom-sbc-1 kamailio[9750]: {1 101 ACK 64AA4E6C-874011E7-9A729B5A-3D9194E8@peer} 7(9760) DEBUG: tm [t_lookup.c:459]: t_lookup_request(): start searching: hash=54992, isACK=1 Aug 23 16:47:12 modcom-sbc-1 kamailio[9750]: {1 101 ACK 64AA4E6C-874011E7-9A729B5A-3D9194E8@peer} 7(9760) DEBUG: tm [t_lookup.c:494]: t_lookup_request(): proceeding to pre-RFC3261 transaction matching Aug 23 16:47:12 modcom-sbc-1 kamailio[9750]: {1 101 ACK 64AA4E6C-874011E7-9A729B5A-3D9194E8@peer} 7(9760) DEBUG: tm [t_lookup.c:641]: t_lookup_request(): no transaction found Aug 23 16:47:12 modcom-sbc-1 kamailio[9750]: {1 101 ACK 64AA4E6C-874011E7-9A729B5A-3D9194E8@peer} 7(9760) DEBUG: tm [t_lookup.c:1070]: t_check_msg(): msg id=104 global id=104 T end=(nil) Aug 23 16:47:12 modcom-sbc-1 kamailio[9750]: {1 101 ACK 64AA4E6C-874011E7-9A729B5A-3D9194E8@peer} 7(9760) exec: *** cfgtrace:request_route=[WITHINDLG] c=[/etc/kamailio/kamailio.cfg] l=231 a=2 n=exit It explicitly states that no transaction is found, after initiating pre-RFC3261 (why?) transaction matching.

Hello! I want to build distributed topology with one KAMAILIO and 5x RTPENGINEs for each region. I will have dedicated links between these sites, so I can garantee somehow voice quality. If one customer from region1 calls customer region2, RTP should go: Customer1->RTEPNGINE1->RTPENGINE2->Customer2 So the main question: Can one Kamailio build "call" between two RTPENGINEs ?

Diaplan module
by Nelson Migliaro 24 Aug '17

24 Aug '17

Hello, I am trying to use the dialplan module but I am having this problem: First of all, I pull the "dpid" value from the two first digits of the dnis: $var(dialplan_vendor) = $(rU{s.substr,0,2}); Then if(!dp_translate("$var(dialplan_vendor)","$dlg_var(servicio)/$var(ani_dialplan)")) { xlog("L_NOTICE","Error al seleccionar el dialplan\n"); sl_send_reply("403", "Not allowed"); drop; } But when I test everything I get: ERROR: dialplan [dialplan.c:233]: dp_get_ivalue(): no AVP, XAVP or SCRIPTVAR found (error in scripts) I think the problem is related to variable $var(dialplan_vendor). It is set up as string due to the transformation and dialplan need a integer. If I set up the variable this way for testing: $var(dialplan_vendor) = 18, it works correctly. Question, how can I transform the sting into a integer? Thank you Nelson.

Consistency: -1 sometimes true, sometimes false
by Sebastian Damm 24 Aug '17

24 Aug '17

Hi, we recently stumbled upon the following problem: We had something like this in our route: $var(ret) = allow_address("2"); if ($var(ret)) { do_something; } Turns out, this always evaluates to true, no matter whether the IP address really is in address group 2 or not. The values in $var(ret) are 1 or -1, depending on the outcome of allow_address(). However, if we write it this way if (allow_address("2")) { do_something; } the code inside is only executed if the IP address is in address group 2. Is this some kind of inconsistency? Should negative values in variables evaluate to true or false? Best Regards, Sebastian

Feature request: USRLOC jsonrpc ul.add - set all entry fields
by Dmitry Sytchev 23 Aug '17

23 Aug '17

Hi Daniel! Looking into code it seems RPC functions of USRLOC don't allow setting all fields for USRLOC entry, for example, Received and Socket. It would be great if we can set these, because we need to have ability to transfer contacts from other server to Kamailio. I think at present this can be done sending specially crafted fake REGISTER packets or calling special route from HTTP with some tricks for saving contact and received, but as for me it would be great to set it from RPC because we already have ul.add method. It also would be cool if we can use named parameters in JSONRPC params: {} section with names corresponding to usrloc fields, like 'table', 'AOR', 'received' and so on. Maybe on specual key not to mix with current 'params'. Thanks for your great work! -- Best regards, Dmitry Sytchev, IT Engineer

23 Aug '17

Hello, I have several Asterisk sending calls to a centralizad Kamailio. I would like this Kamailio to set up the caller id number of the calls. I am using the uac_replace_from function but I would like to pull the caller id from a database to set up the number based on the sip vendor the call is forwarded What would be the correct way to do that? I was thinking of: sql_query("ca", "select ddi from ddi_table where xxx= $rU limit 1", "ra"); $avp(dnis) = $dbr(ra=>[0,0]); sql_result_free("ra"); But I am afraid of causing a bottheneck on the database.

I noticed that the following is available on the snmpstats module but it only holds a counter that keeps increasing until I restart kamailio process: snmpget -v 2c -c public localhost KAMAILIO-MIB::kamailioTotalNumFailedDialogSetups.0 Also I think the above includes all cause codes that are between 3xx-6xx. Cheers, --Olli

Save original $fU, $rU
by yu＠yu-boot.ru 22 Aug '17

22 Aug '17

Have a problem with Asterisk. When callee behind Asterisk hangs up first, it sends back BYE with swapped From and To fields, which affects Kami CDRs rendering them useless. I've tried to save original From/To to AVPs on initial INVITE but they are empty when CDR is written. How to solve this? -- Отправлено из myMail для Android

Kamailio / Asterisk and multidomain
by Cyrille Demaret 22 Aug '17

22 Aug '17

Hi, I'm new to Kamailio and I'm trying to use it as a front SIP proxy to one or more asterisk. Unlike to the "Kamailio 4.0.x and Asterisk 11.3.0 Realtime Integration" tutorials, I would like to let Kamailio handle registrations, calls between users and other basic functionalities. Asterisk will only handle advanced features like voicemail, advanced dialplan configuration,. My problem is that It needs to be multidomain. My network will be as follow with 2 network interfaces for Kamailio and a private lan between Kamailio and Asterisk : Public interface ip 1.2.3.4 ----> [Kamailio] <----- Private interface 192.168.100.10 <----------------> 192.168.100.11 [Asterisk] When I send a call to asterisk, the domain is sent in the from field of the INVITE and I can do what I need on the Asterisk dialplan (I can get the SIP domain using the ${SIPDOMAIN} variable). My problem is when I need to send a call back to Kamailio for example to reach another user of the domain. I'm using Asterisk 14 with PJSIP with the following config : [kamailio] type=endpoint transport=transport-udp context=from-kamailio disallow=all allow=ulaw aors=kamailio [kamailio] type=aor contact=sip:192.168.100.10:5060 [kamailio] type=identify endpoint=kamailio match=192.168.100.10 If I use this dial string in my Asterisk dialplan "PJSIP/ kamailio /sip:200@testdomain.com", Asterisk contact directly testcomain.com without going through the local IP of my Kamailio. I can't send a domain to Kamailio in the INVITE request. Does anyone can help me on this or maybe simply tell me that I'm not going to the good direction? :) Thank you, Cyrille

problems with use_dst_blacklist and ICMP "Destination Unreachable"
by Valentin Christoph 22 Aug '17

22 Aug '17

Hi all, Question: * Does the TM destination blacklist work, if destination host responds with ICMP "Destination Unreachable"? Discussion: I have got an IMS scenario, where I think the destination blacklist is not working and try to find the reason. I use UDP between two Kamailio SIP Proxies (P-CSCF and S-CSCF) and send a SIP request to the primary instance of the S-CSCF. However the destination Kamailio has been stopped with kamctl stop before and so the destination machine responds with ICMP "Destination Unreachable". DNS Failover towards secondary S-CSCF instance works perfectly. Destination Blacklist does not work. I.e. the next SIP Request is sent to the primary host again, before failover to secondary host applies. I would have expected the request would be sent to secondary host immediately. >From the description in doc/dst_blacklist.txt [...] A destination is added to the blacklist when an attempt to send to it fails (e.g. timeout while trying to send or connect on TCP), or when a SIP timeout occurs while trying to forward statefully an INVITE (using tm) and the remote side doesn't send back any response.[...] I think the destination blacklist does not work, because an ICMP Response "Destination Unreachable" is received.

append_branch and tls
by James Cloos 21 Aug '17

21 Aug '17

[I see I posted this to -dev instead of -users; fixing that -JimC] When using rewrite_ruri() and append_branch() to set a list of next hops to try, what is the proper syntax to specify that a given route should use tcp or tls/tcp? I've mostly used a single next hop via t_relay_to_tcp() or t_relay_to_tls(), but need route stacks now. -JimC -- James Cloos <cloos(a)jhcloos.com> OpenPGP: 0x997A9F17ED7DAEA6

Converting to kemi
by James Cloos 19 Aug '17

19 Aug '17

[I see I posted this to -dev instead of -users; fixing that -JimC] I'm working on converting some configs to kemi lua and have a couple of questions: First: Does KSR.pv.get() support multiple pseudos in a single call? The examples such as misc/examples/kemi/kamailio-basic-kemi-lua.lua make several calls, but also do things like KSR.pv.get("$T_branch_idx]") to avoid having the append "]" to the string. That makes me wonder why that file has code like this: KSR.dbg("new branch [".. KSR.pv.get("$T_branch_idx]") .. " to ".. KSR.pv.get("$ru") .. "\n"); instead of like: KSR.pv.get("[$T_branch_idx] to $ru\n") Second: Is it still the case that, eg, event_route[xhttp:request] cannot be in the kemi lua code? There was another. Perhaps I'll recall what it was... :( -JimC -- James Cloos <cloos(a)jhcloos.com> OpenPGP: 0x997A9F17ED7DAEA6

Kamailio_428 memory usage
by Evgeniy G. 18 Aug '17

18 Aug '17

Good afternoon! Can you please tell us how the Kamailio works with shared memory. The fact is that there was an accident in which Kamailio reported an error - little common memory. This happened a day later as I added the dialplan module. After that, I began to monitor the values: used_size real_used_size max_used_size free And I saw that I can not properly assess. I note that the server does not process calls, it is idle. After the server is started, the indicators are as follows: used_size: 63 real_used_size: 146 max_used_size: 146 free 106 After rebooting the module (for example, drouting, in which the data has not changed): used_size: 63 real_used_size: 193 max_used_size: 231 free 62 I found, a description, the reasons for the increase in memory after rebooting the modules, I quote "As suggested by Daniel, for carrierroute reload, we need the same amount of memory as it used to be. Block when reloading the table. " But why: 1. after increasing the memory the server frees only real_used_size 2. That that is specified as real_used_size on my observations can not be released in current of several days (probably weeks). 3.If in this state again to reboot the module (the same one that led to an increase in memory), the memory does not increase. Question: during what time should kamailio release the memory specified as real_used_size? Also what is considered as real_used_size? -- View this message in context: http://sip-router.1086192.n5.nabble.com/Kamailio-428-memory-usage-tp161327.… Sent from the Users mailing list archive at Nabble.com.
