[OpenSIPS-Users] opensips 2.1 call_center queue position

Thu Oct 13 14:38:29 CEST 2016

Hi Bogdan,
Thanks for the response, and yes I understand you are envisioning a solution, which I appreciate as usual :)
Yes the addition of cc_pos would work for me, as I can extract any number of variables form the ruri, this would do the job.
Thanks
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" 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 
      - cc_eta being the estimated time to wait in seconds and cc_pos
      the position in the queue.

      What do you think of this ?

        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
