Recover call in ringing state
by Devang Dhandhalya 04 Jan '23

04 Jan '23

Hello All I have below setup : SBC -> kamailio -> Media server(remote) -> web-client Call comes from sbc to kamilio and it relays to Remote server to end user, In Ringing state if remote server goes down then in kamailio there is any way to Recover that ringing call like we can generate new invite for other Remote server which is active state, for relaying call i am using dispatcher module.. I tried with tm.cancel RPC command but it works only if the remote server is running , when I crash the remote server at that time tm.cancel is not generating cancel to remote server. Please suggest if there is any other way to generate INVITE.

dialog_vars accumulating in database?
by Benoit Panizzon 20 Dec '22

20 Dec '22

Hi List I noticed that the database is accumulating entries on dialog_vars. I don't know when and why this is happening. Are there any special measures that have to be taken like making sure to unset variables after using them to prevent this? Or is this something which is supposed to happen when kamailio is restarted?

imc sends all messages with Content-Type: text/plain
by Joey Golan 02 Dec '22

02 Dec '22

Hello, I'm checking the imc module and it appears that imc sends all messages with hard-coded content type header so if client sends an application/im-iscomposing+xml message, other clients receives the message with content-type text/plain which is very confusing. I think the right behavior is to take the content-type header from the original message and use it in the messages imc sends. Is there a workaround that might help me achieve that?

Hello Igor, yes - you can use a RPC command, I think its in corex module.

Re: [SR-Users] uac_req_send() multi-process synchronization problem
by Henning Westerholt 30 Nov '22

30 Nov '22

Hello, not sure if I fully understand the problem. But regarding another user is registered with the same IP address as a previous user, there are several mitigations. To give two options: you could choose a really short re-registration time, you could use TCP and when you lose the connection you delete the contact.
