remote ip address of sender and receiver
by vuleetu 30 Jun '17

30 Jun '17

Hi, all Is there any way to get remote ip address of both sender($si) and receiver(?)? I am configuring kamailio with multiple rtpproxy sets. Basically, rtpproxy set will be choosed based on the country those ip addresses of caller and callee belong to. Lets say if caller and callee are both in US, set 1 will selected. If they are not in the same country, set 2 will be selected. I dont know if there is any way to do that. Best regards Fisher

Segfault on kamailio 5.0.2. Suddenly stops processing traffic, then generates a core when restarting
by Joel Serrano 29 Jun '17

29 Jun '17

Hi all, I'm running into a weird situation with our newly deployed Kamailio servers. These servers are only doing SSL offloading and load balancing between another set of servers. Debian v9.0 + Kamailio v5.0.2 (from kamailio50 repository). After some time of running, kamailio suddenly stops responding to any request but the proccess is still alive. When we restart the service, a core is generated. I have opened an issue in GitHub: https://github.com/kamailio/kamailio/issues/1172 I'm … [View More]

Detect network range in UDP traffic
by Emanuele Gambaro 27 Jun '17

27 Jun '17

Hi to all I have the following scenario (Kamailio 5 and rtpproxy) *) Bob on a wifi network calls Alice *) During the call, Bob losts his wifi network (and so also changes his IP address) *) The RTP flow is interrupted With asterisk, disabling “Strict RTP” option, the flow does not interrupts: Asterisk detect the new IP address and sends the audio packets to the new IP address. It is possible to setup this behavior also with Kamailio? -- Emanuele Gambaro --- email: emanuele.gambaro(a)pynlab.… [View More]

Question about sip call setup : three-way handshake
by Abdoul Osséni 27 Jun '17

27 Jun '17

Hello, During three-way handshake (SIP call setup - INVITE-200 OK - ACK) and before generating or sending the final 200 OK call, is there a way to confirm the caller is still available (no network issue)? I want to detect broken connections (ex. the uac uses 3G network) before generating/sending/forwarding the final 200 OK. Thanks. Regards Abdoul

I am using Kamailio + Sems + Rtpproxy for conference call. Once user join to conference, if user send dtmf, sems is detected but it does not forward DTMF (in RTP) to all user in conference. I think rtprelay_dtmf_detection should be configured? Do you have any idea to help? Thanks, Nhan

auth users using inmemory lookups
by Grant Bagdasarian 26 Jun '17

26 Jun '17

Hello, We're currently using the auth_db module and calling the function auth_check to check the Authorization header and authenticate the request. We moved most of our code to in-memory lookups (using htable), since we do not want our Kamailio servers to be DB dependent. Just to be sure, if we move the authentication to in-memory lookups we should use the auth module and call the pv_auth_check function instead right? The passwords in our users table are all stored in MD5, so we basically … [View More]

Problem with t_relay() and VPN tunnel
by Carlos Ruiz Diaz 24 Jun '17

24 Jun '17

Hi, I have two SIP servers, *A* and *B*, connected each other though a OPENVPN tunnel. The server *B* needs to t_relay() every SIP message containing the method MESSAGE to the server *A* but these messages never reach destination. I have tested the tunnel connectivity and works fine. I wrote a Perl script (located in *B*) that sends SIP MESSAGES to Kamailio (located in *A*) trying to figure out what is happening but these messages are received by *A* and processed correctly but when *B* does … [View More]
