Hello all,

Does anybody use Asterisk for forwarding calls from CGPro to a VoIP
I have a specific question regarding gatewaycaller forwarded calls not
being able to last longer than 10 seconds after the called party
answers. It looks like Asterisk expects an ACK from CGPro and drops the
call after a timeout.
The problem is specific to pair gatwaycaller/Asterisk. When I use sipgw
routing entry instead of gatewaycaller everything works just fine.

Here is what I get in Asterisk log 10 seconds after the remote party

[Feb  5 12:06:41] WARNING[4537] chan_sip.c: Maximum retries exceeded on
transmission for seqno

to our critical packet.
