[Freeswitch-users] CISCO 2811 Freeswitch IVR

Thanks for the help so far.


Here is a pastebin of FreeSWITCH output:
http://pastebin.com/i6Qgc7ws

Notice how the "has been answered" log message comes immediately
(within a few milliseconds) after the call was originated. I think
this would suggest that the CISCO is immediately sending a 200 OK, as
you suggested. I also turned on CISCO debugging, but I'm just trying
to figure out how to get the information regarding SIP messages back
to Freeswitch. I'll run the test again and see if I can get some
useful CISCO debug.

Which "debug ccsip" commands are relevant to what I want for the CISCO
SIP debugging?


Thanks!

> I think I've a similar problem related to callcenter app. When I made an originate like this:

> 2500 is an extension that leads to a callcenter application. In this case, we dial first to the queue and when an agent answered we call to the customer. As far as I know
> When the A-leg reaches to the queue, without selecting an agent, the call is automatically sent to the B-leg. As far as I see, there is a pre-answer method that fs needs to send the media to A-leg.
> In order to try to avoid this, I tried using ignore_early_media=true as part of the originate in A-leg and/or B-leg, with no luck.
