Possible memory leak on 5.5.x (new)?
by George Diamantopoulos 25 Jun '21

25 Jun '21

Hello all, I'm still investigating the (most likely non-kamailio-related) memory leak of my previous message to the list, there have been no developments so far. I'll update if anything changes. This concerns a new finding which seems to affect kamailio 5.5.x. I have two kamailio instances receiving the same traffic via round-robin. I upgraded only one of them to 5.5.1 and left the other to 5.4.6 as I feared of any issues arising. I was lucky to do so, because with identical configuration, 5.… [View More]

rr module: record_route_advertised_address()/record_route_preset() do ignore custom user AVP
by Valentin Christoph 25 Jun '21

25 Jun '21

Hi, Maybe a discussion for the DEV mailing list???? Want to overwrite the FQDN by a NATed IP address in the topmost Record-Route of an outgoing INVITE request. Cannot set the advertise parameter (this must tell the FQDN for all other situations), only in some special situations I want to overwrite the FQDN in Record-Route. My solution would be to implement in the Kamailio source code (rr module) that not only record_route() uses the get_custom_user() function, but the other both functions … [View More]

Kamailio $Rp variable showing wrong port
by Shahid Hussain 25 Jun '21

25 Jun '21

Hi, I have configured the dispatcher default socket as below IP , the expectation here is that kamailio should send all traffic from this IP (port will be ephemeral) over TCP. modparam("dispatcher", "ds_default_socket", "tcp:172.27.45.219:5060") This system also listens on port 8080 which is meant for websocket communication (dispatcher communication is over non websocket). Kamailio is sending an OPTION message to dispatcher IP over TCP on 5060 and getting 200 OK response but Kamailio … [View More]

S-CSCF and I-CSCF
by Jayanth Acharya 24 Jun '21

24 Jun '21

Hi, Have found example configuration for S-CSCF, I-CSCF and P-CSCF in Kamailio repository, and a S-CSCF module for the registered user data, but no recent updates. Wondering if anyone can share insights into how widely it has been used, or interops done in say telco networks with it ? Does it handle third-party registrations, is it actually able to do a Cx interaction with HSS ? Finally, how have these components that make up the IMS-core from SIP signaling standpoint, been tested ? Are … [View More]

AVPs in Switch/Case
by Joel Serrano 22 Jun '21

22 Jun '21

Hi guys, Quick question, are AVPs valid in "switch" as "case"'s? Example: $avp(var1) = "101"; $avp(var2) = "201"; switch($rU) { case "$avp(var1)": ... break; case "$avp(var2)": ... break; default: send_reply("403", "Forbidden"); exit; } For some reason I can't get the case to match, and I'm thinking it's not using the actual value of $avp(var1) and instead it's using literally "$avp(var1)" as a string. NOTE: I also tried without putting the AVPs in quotes, but Kamailio complains and doesn'… [View More]

execute callback every X minutes mid call
by Avremy Cohen 22 Jun '21

22 Jun '21

Hi I am trying to execute code every X min in active calls and I cant seem to find any way to do this. I basically have a function that checks if the user has balance and permission to carry on the call and the callback should trigger it every X mins. The call_control module doesnt work for me since A. It doesn't trigger a function it just ends the callback B. it uses an external application to calculate it any advice is appreciated Avi

Hello Ovidiu, Interestingly, that fixed the problem. I can now continue to make progress. Why does not forking and/or logging to stderr cause this to happen? Thank you!

Unable to establish TCP connection with Kamailio
