Hi Mikhail,
1) I'm aware of the issue with the silence during the agent ringing - to
be honest, we did some scripting workaround to use rtpproxy to inject a
ringback tone to caller while we ring the agent :D.
But the proposed solution is definitely better, still it needs to be
evaluated if possible or not from the coding perspective (more or less,
it depends on how the b2b works in OpenSIPS)
Could you please take this report/issue/topic and create a new
issue/ticket on the github tracker, so we can have it on the roadmap ?
2) I suppose the fault is related to frame 35-37 in callcenter.pcap,
right ? Also please open a ticket here and attach the pcap + opensips
logs in level 4 (dbg).

Hi Bogdan-Andrei,
1)
Right. I'll try to explain more detailed what I mean:
case 1 - as I see how opensips working
Caller calls and Agent is not available
caller is listening intro
caller is listening music
Agent become available
Music stops, caller listening silence - Agent ringing
Agent don't answer within within defined period, for example 20
seconds, and Caller is listening silence 20 seconds!
Call returned to queue
Caller starts to listening music from beginning, because opensips
makes new call to ivr server
Agent become available
Music stops, caller is listening silence - Agent ringing
in a 10 seconds Agent answers, so 10 seconds caller listen silence again.
case 2 - as I know how it should be
Caller calls and Agent is not available
caller is listening intro
caller is listening music
Agent become available
Music don't stops, caller continue listening music without
interrupt - Agent ringing
Agent don't answer within within defined period, for example 20
seconds, but Caller do not know about it, he sill listening music
without interrupt.
Call returned to queue, caller continue listening music without interrupt.
Agent become available
Music don't stops, caller continue listening music without
interrupt - Agent ringing
in a 10 seconds Agent answers, at this point caller stop listening
music and start talking to agent.
2)
I made 2 calls for test:
1-st - direct call from caller to agent. Hold by caller and agent
works good.
2-nd - call from caller to number 3001 routed to ivr by
cc_handle_call() command
call routed to intro 0081 and then to agent. Hold did not work.
I found that it seems that agent’s xLite did no receive some sip reply
and after 30 seconds after answer xLite sends bye by itself.
Also there are errors in opensips.log
sip log captured with sngrep I uploaded to my server:

Hi Anton,
In regards to your experience with the call_center module:
1) You mean, while the call is ringing on the agent side, the caller
gets dead-air, right ?
2) It should be working, do you have a pcap on that ?

Hi Антон,
in my tests I have working greeting and queue and I sill have
issues I described before:
- when Invite is going to agent, caller hear silence, because
opensips stops call to medial server.
- can't place on Hold either agent or caller, opensips sends "400
Not Acceptable".
I guess this is a feature/bugs in call_center module.
My goal is to manage call_center with more then 1000 agents and
migrate from our current platform, but this troubles stops moving.
It would be very cool if the developers or those who use the
call_center module have commented on these problems.
