I posted a
problem earlier thinking it was due to a lack of sound card. Several
members stated that you do not need a sound card to play audio to a PRI
channel. I did some further testing and discovered that there is a problem
with call progress tones or signaling on my PRI. I think that
the reason I am not hearing audio from the MeetMe() or Playback() apps. is
because the the calling side of the PRI (NEC IPX), is not seeing the Answer
signal. I believe it is waiting for a ring and/or
answer condition even after Asterisk has executed an Answer() and
Playback().
The only other
problem that I am having with my setup is that the CONSOLE/DSP is not
functional... I am not sure if the two problems are related. Any help is
appreciated. Please see my two examples
below:
Unless my incoming
DID (2000), is pointed to a SIP station that is registered and
functional, I do not receive call progress tones on inbound
calls.
If I point the DID
to an application like:
[inbound_pri]
; PRI from the NEAX2400
; PRI from the NEAX2400
exten =>
2000,1,Wait,3
exten => 2000,2,Answer
exten => 2000,3,MeetMe,|Mps
exten => 2000,4,Hangup
exten => 2000,2,Answer
exten => 2000,3,MeetMe,|Mps
exten => 2000,4,Hangup
I will not hear any
initial ringback, and once answered there will be no audio on the
channel.
If I point the DID
to a registered SIP station like:
[inbound_pri]
; PRI from the NEAX2400
; PRI from the NEAX2400
exten =>
2000,1,Wait,3
exten => 2000,2,Dial,SIP/2001,15,Tr
exten => 2000,Hangup
exten => 2000,2,Dial,SIP/2001,15,Tr
exten => 2000,Hangup
It will provide
ringback tone to the calling channel on the PRI, and when the ringing
SIP phone answers there will be 2-way speech path.
