[OpenSIPS-Users] opensips 2.1 call_center queue position

Hi Bogdan,
Yes I will test with a real queue and let you know, hopefully I will have a test scenario up and running this week.
In terms of your questions;
For 1) For my needs I think I only require it for the MOH/queue announcement, however if its simple to add, I can test it out for sure, I think the more information available the better, certainly when looking to replace older systems such as a cisco which provide quite alot of information to the caller.
And for 2), adding ETW would be useful for sure, as the more information options available the better when looking to implement a queue system like this for me.
I will keep you posted with the testing.
Thanks again for the patch!
Jon

Hi Jonathan,
I was not able to test it with a real queue, so let me know if it really does the job (in terms of reporting the real position in the queue).
Some questions:
1) currently I add that value only when sending to the queue / MOH - do you foresee any need to be added for other announcements like for welcome ?
2) will it be useful to add the ETW (estimate time to wait) ? is it useful ?

Hi Bogdan,
Hope you are well.
Yes that patch works, it stops the crash, and adds the parameter;
Request-Line: INVITE sip:7777 at 1.2.3.4:5080;cc_pos=0<mailto:sip:7777 at 1.2.3.4:5080;cc_pos=0> SIP/2.0
Which is great!
I will now get to work on the solution, thanks again.

Hi Bogdan,
Sorry for the delay.
I installed directly via make install, not via packages.

Have you installed OpenSIPS via packages ? or directly via "make install" ?

I installed 2.1 from sources, so whats the best way to do this?

For sure it is a patch issue. if you have a backtrace, it will useful.

Hi Bogdan,
Thanks very much for this.
I have just applied patch (installed from sources so when to call_center module directory and ran patch < call_center_pos.patch) then did a recompile.
However when I now route to the call center (cc_handle_call) it generates a core and kills opensips;
!!!!user 2000 has Callqueue set so send to Call Queue Route
Nov 2 07:53:42 HPBXProxy1-beta /sbin/opensips[21141]: NOTICE:core:io_wait_loop_epoll: EPOLLIN(read) event: epollwait() set event EPOLLHUP - connection closed by the remote peer!

Do you need me to backtrace/debug through to get the issue? Or is problem how I applied patch?
Many thanks
Jon

Hi Jonathan,
Please give it a try to this patch - it is not really tested, but when the call is sent the Queue announcement, it should have a ";cc_pos=xxx" parameter giving the position is the queue (0 being the first to be dispatched to agents).
Let me know if it works.

Hi Bogdan,
Sorry cant recall If I replied to this.
Is cc_pos available now to extract from the module?
Thats the only thing I need then I can implement call center which I think will be much more scale-able than the other approach I am using with FreeSWITCH, I would use that just for announcements.
Any response/help appreciated.
Jon

Hi Jonathan,
No, currently this is not possible. I was trying to envision a solution for your need.
But, checking the code, it is really difficult to add the headers to the INVITEs originated by OpenSIPS (via the B2BUA), as we need some flexibility (different headers to different INVITEs belonging to the same B2B scenario , and even more, we need to traverse couple of internal APIs - to propagate the hdrs from Call center module all the way to TM).
So, a simpler approach may be to add such extra info as URI params to the RURI. Like if you have the RURI "sip:queue at 192.168.1.10:5060"<mailto:sip:queue at 192.168.1.10:5060> for the queue/waiting playback, the RURI in the INVITE to the media server will look like : sip:queue at 192.168.1.10:5060;cc_eta=40;cc_pos=10<mailto:sip:queue at 192.168.1.10:5060;cc_eta=40;cc_pos=10> - cc_eta being the estimated time to wait in seconds and cc_pos the position in the queue.
What do you think of this ?

Hi Bogdan,
Yes being able to grab the queue position would be perfect.
Is that possible?
Thanks

Hi Jonathan,
When a call is mapped to a flow / queue (before playing the welcome message), we know the ETA (estimated time to wait) and when is placed in the queue (before playing the queuing) we internally know the position in the queue.
Would it help to have the position in the queue placed into a custome SIP header, when sending the INVITE to the message_queue URL ? or to the welcome message ?

Hello Bogdan,
Thanks for the response.
In terms of my question, with a number of queuing platforms, they have the capability to tell the caller, what position they are in , and when they are likely to be answered.
I just wondered if this logic was already within the module, or if I would need to use an external code/script to facilitate this function?
As I presume call_center tracks the number of calls currently in a queue ? I would then want to be able to extract that information, and if a caller was for example in 3rd place in a queue, I could inject the relevant audio from freeswitch to tell them their current position?
Does that make sense? :) Just wanted to know if its something this module can do?
Thanks
Jon

Hello Jon,
The message_queue is a SIP URI pointing to an audio announcement to play to roll of the waiting/in-queue playback. This needs to be an announcements that never ends (from the perspective of the media server); only the the OpenSIPS Queue may terminate the playback, when it decides to take out the call from waiting and to deliver it to an agent.
As for your question, I'm not sure I understand what you mean by "inject a message with queue position for the caller in question" - could you detail please ?

Hi guys,
I have implemented an opensips/freeswitch environment, and I wish to add call queues to it, and I like the look of call_center, so just checking this out in comparison to mod_callcenter in FS world.
My main question is if using the call_center module if you can inject a message with queue position for the caller in question, as I cant see that in documentation, I only see message_queue which I assume could be used to report the callers position, but just wondered if anyone has done this and if they could give me some tips as to if possible?
Many thanks
Jon
