[OpenSIPS-Users] opensips 2.1 call_center queue position

[Bogdan-Andrei Iancu]

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 ?
