[cisco-voip] Integrating Channel Bank IVR with 2811/CCM

[Wydra, Jason]

Did you try putting the incoming-called number statement on the pots
peer instead of the VoIP?

Subject: [cisco-voip] Integrating Channel Bank IVR with 2811/CCM

 

I am trying to integrate a legacy IVR into our CallManager environment.
The IVR has a T1 interface which is set up as a "standard loop-start
channel bank" with answer supervision. 

It is connected to a T1 port on a 2811. The controller/ds0-group is set
up as follows: 
controller T1 0/0/0 
framing ami 
linecode sf 
clock source internal 
ds0-group 1 timeslots 1-24 type fxs-loop-start. 

I have a dial-peer configured for access using DN 8082 (route pattern
configured in CCM): 
dial-peer voice 13 pots 
destination-pattern 8082 
port 0/0/0:1 

I also have a voip dial-peer configured: 
dial-peer voice 100 voip 
destination-pattern 8522 
session target ipv4:10.xxx.xxx.xxx 
incoming called-number 8522 
dtmf-relay h245-signal cisco-rtp 
codec g711ulaw 

I can get calls from an IP phone to the IVR without an issue. I hear the
recording and can pass DTMF to the IVR without issue. 

The goal is to have the IVR place a call to an IP phone. This is where
we're having trouble. The IVR is going off hook and says it hears dial
tone. It is matching the above pots dial-peer when it goes off-hook. 

However, the 2811 gateway does not appear to receive any digits (IVR is
directed to send 8522), and thus can't hit any outbound dial-peer. 

Have looked at debug voip ccapi inout, debug voip vtsp all, debug h245
events, and can't really see what is('nt) happening. 

Does anyone have any suggestions as to what might be happening here?
