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

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

UDP send: Operation not permitted

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
by 张顺通 08 Mar '16

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.
