Track-Calls does not work with mod_callcenter

5 Jan 2023

      Hi,

I'am using freeswitch in order to build a call center using the mod_callcenter module. I would use the track-calls capability in order to recover calls that are in the call center queue.
I have read the following documentation about HA:
https://developer.signalwire.com/freeswitch/FreeSWITCH-Explained/Configurati...
For now I want just recover the active calls from my unique freeswitch instance after a crash, no cluster, no redundancy, juste one instance of freeswitch plus a opensips proxy.

I have put <param name="track-calls" value="true"/> in my profile I use only one profile all UAC are external and are not register to the freeswitch.
I use the freeswitch local DB since I have only one freeswitch instance.
I have also put <X-PRE-PROCESS cmd="set" data="api_on_startup=fsctl recover"/> in the vars.xml in order to recover call when freeswitch restart..

My topologiy is the follow:

external UAC (client) ===> own SIP server ===> OPENSIPS(10.10.13.196) ===>FREESWITCH (10.10.13.1249) ===> own SIP server ==> external UAC (agents)

Opensips receives INVITE from de UAC client and proxies the INVITE to FREESWITCH freeswitch execute dialplan and the callcenter application and when it find a UAC agents Available it send them an INVITE.
UAC client and agents are localized  behind our own SIP server

For the test I have put all external UAC agents associated to my queue in the status 'Logged Out" in order that the incoming call stay inside the queue.

When the UAC client call the queue, I have one calls active.
Then in the fs_cli I execute "fsctl crash". After 1 or 2 second the call is active again in the queue, but some secondes later the call  hangup.

When I see the SIP traces I see that when freeswitch recover the call it send a re-INVITE. To the UAC client. The  freeswitch receives well  a 100 Trying and a SIP 200 OK but  when freeswitch send the ACK, the ACK is not handle by the UAC client and UAC client send a SIP 200 OK until timeout and UAC client send a BYE.

My questions are:

  *   Is it normal to find  record-route headers in the re-INVITE? because the re-INVITE is part of the initial dialog. Why freeswitch adds these record-route headers and does not only use Route headers?.

  *   I think since record-route headers are added to the re-INVITE can this lead to a bad 200 OK and a bad ACK?

Here is the entire SIP dialog view from the freeswitch instance:
I added in front of the important part of the logs some comments prefixed by ///

///
/// UAC client send INVITE to the opensips (private IP:10.10.13.196,  public IP: 92.222.241.128) and proxies the INVITE to freeswitch (10.10.13.249)
/// the UAC client is  behind our own SIP server (35.234.91.59)
/// opensips use a public IP (public IP: 92.222.241.128) in order to be seen by our SIP server
