Hi,

I wants to bridge calls with particular DID, which landing on one PRI span (Span_1) to another PRI span (Span_2).

I'm able to bridge the calls between PRI span and able to talk to each other.

My problem is that sometimes DTMF which received on Span_1 is not sending to Span2 and vice-verse. DTMF tones are hearing partially on receving end.

Sometimes after a some delay (30-60 seconds) am getting the DTMF, but that's too some dtmf are missing.

If I hangup the line while the dtmf is in queue then the dtmf are generating on the next call on the same line.

But when I bridge the call on PRI with sip channel then am not getting any problem.

I think the following log in freeswitch is usefull

 

2012-06-12 18:58:38.379506 [DEBUG] mod_openzap.c:725 queue DTMF [1]

2012-06-12 18:58:38.019513 [DEBUG] switch_ivr_bridge.c:391 Send signal OpenZAP/1:1/8040327325 [BREAK]

after this  it takes a while to generate dtmf
