At db I keep key IP with value TIMESTAMP Intresting that route, that givesme this result idependend of WS or UDP endpoint. IT does not know about it anything.

Route Between WebSockets without rtpengine getting into the mix
by Don Fanning 05 Mar '15

05 Mar '15

Hello All, Prior to going down the rtpengine path for another need, calling was working fine between WSS client. Now that I've added in some pieces from caruizdiaz's config [ https://github.com/caruizdiaz/kamailio-ws/blob/master/kamailio-ws.cfg] relating to SETUP_BY_TRANSPORT, it has broken that functionality. Is there a way to skip rtpengine if the originator and destination are both on wss? route[RELAY] { # enable additional event routes for forwarded requests # - serial forking, RTP relaying handling, a.s.o. if (is_method("INVITE|BYE|SUBSCRIBE|UPDATE")) { t_on_branch("MANAGE_BRANCH"); t_on_reply("MANAGE_REPLY"); } if (is_method("INVITE")) { route(SETUP_BY_TRANSPORT); if(!t_is_set("failure_route")) t_on_failure("MANAGE_FAILURE"); } if (!t_relay()) { sl_reply_error(); } exit; } route[SETUP_BY_TRANSPORT] { if ($ru =~ "transport=ws") { xlog("L_INFO", "Request going to WS"); if(sdp_with_transport("RTP/SAVPF")) { rtpengine_manage("rtcp-mux-demux trust-address replace-origin replace-session-connection ICE=force DTLS=passive"); t_on_reply("REPLY_WS_TO_WS"); return; } #rtpengine_manage("rtcp-mux-demux trust-address replace-origin replace-session-connection ICE=force DTLS=passive RTP/SAVP"); t_on_reply("REPLY_FROM_WS"); } else if ($proto =~ "ws") { xlog("L_INFO", "Request coming from WS"); rtpengine_manage("rtcp-mux-demux trust-address replace-origin replace-session-connection ICE=remove DTLS=passive RTP/SAVP"); t_on_reply("REPLY_TO_WS"); } else { xlog("L_INFO", "This is a classic phone call"); rtpengine_manage("replace-origin replace-session-connection"); t_on_reply("MANAGE_CLASSIC_REPLY"); } } Thanks for any help! -Don

segfault problem with unixodbc module
by Lucas Wals Ochoa 05 Mar '15

05 Mar '15

Hello, this is the first time I send a question here, hope my english is good enough to explain my problem. I have a Kamailio 4.1.8+RTPProxy setup working, but recently I saw RTP Engine proxy, so I decided to give a try. I installed the latest kamailio stable version (4.2.3) and adapt the configuration I have(that uses a MariaDB database), to try the rtpengine module, but I couldn't even start kamailio process, cause I received a segfault problem at unixodbc module. The version of unixodbc that I installed is 2.3.1-10 That was the first time I encounter this error. I thought that maybe the database I have created with the version 4.1.8 wasn't compatible, so I decided to create a new database, but the problem persisted. So I'm here to know if someone know something about this, or have had a similar problem. I attached the system log for Kamailio, and a backtrace I made using "gdb" with the corefile that Kamailio creates when it crash.

WARNING: <core> [local_timer.c:83]: _local_timer_dist_tl(): 0 expire timer added"?
by Anthony Messina 05 Mar '15

05 Mar '15

Good day. Is anyone able to let me in on what this means "WARNING: <core> [local_timer.c:83]: _local_timer_dist_tl(): 0 expire timer added"? I just started seeing this after pulling down 5c1a9df from git and it seems like something that I probably don't want happening. -- Anthony - https://messinet.com/ - https://messinet.com/~amessina/gallery 8F89 5E72 8DF0 BCF0 10BE 9967 92DC 35DC B001 4A4E

Hi All, I'm placing calls between two devices over WSS and sipML5. Connection seems to work and stays up (despite some grumbling sometimes with 603 failed to get local SDP) but my question is the following log entries - could someone translate what is happening here?

How to Use Multiple DMQ Notification Addresses
by Robert Boisvert 04 Mar '15

04 Mar '15

Hello all, I would like to setup a DMQ bus where servers can come on and offline and have DMQ continue working with the online servers. I'm having trouble understanding how to do that with the notification address. Can someone point me in the right direction? More specifically, suppose I have five servers named A, B, C, D, and E. I would like all of them to be on the DMQ bus when active but they may come up at different times. For example, when A, B and C start I want each of them to be on the same DMQ bus. However, the way I understand it, if I make E the notification address none will be on the bus because E is not active. I could create a circular notification chain where A uses B as a notification server, B uses C, and so on. Of course, there are problems when one or more servers are missing from the chain. Any help on this is greatly appreciated. Thanks, Bob

switch called number
by jaflong jaflong 04 Mar '15

04 Mar '15

Hi Guys I want to archive this setup Kamailio to switch called number and the switch to be hidden from the client so there should be no mention of the switched number in any of the messages back to the client. for example phone client calls "alex" kamailio to switch "alex" to "54321" and send to asterisk on response from asterisk, kamailio to revert all references to "54321" back to "alex" before send to client Any suggestions please

TLS conversion
by Kelvin Chua 04 Mar '15

04 Mar '15

I have 2 kamailio servers and 1 asterisk server. 1. asterisk calls kamailio1 2. kamailio1 relays INVITE to kamailio2 3. kamailio2 relays INVITE to client registered using TLS 4. client answers with 200 OK, sends to kamailio2 5. kamailio2 relays 200 OK to kamailio1 6. kamailio1 relays 200 OK to asterisk 7. asterisk sends ACK to kamailio1 8. kamailio1 complains "forward_request(): forward_req: ERROR: cannot forward to af 2, proto 3 no corresponding listening socket" which is because 200 OK has a contact header with tls transport from client 9. call drops in 30 secs which is expected because client never received the ACK any ideas on a fix or workaround?

Any suggestion if I just want to update one or some modules?
by jack wang 04 Mar '15

04 Mar '15

For example, If I modify only the registrar module, I thought the steps were: 1. make modules=modules\registrar modules 2. copy the registrar.so to the installed path And when starting kamailio I got the error message below: ERROR: <core> [sr_module.c:417]: version_control(): ERROR: module compile flags mismatch for [my installed path]/registrar.so I've searched for the answer and it seems to need to re-build and re-install kamailio and all the module again... Is there more efficient way for just updating the specified module ?? Thanks a lot.:)
