[Asterisk-Users] chan_sip.c:495 retrans_pkt: Maximum retries exceeded on call

[AstGrp]

Ok.. Let me start by saying that SJPhone works fine through NAT and the
Cisco phones inside the internal network work fine also... It's just the
Cisco phones on the outside using NAT.

For Testing I opened the Firewall open on the IP for the * Server.  I
have done, everything you recommended below, but still no go... When the
phone registers with port 2842?  Not the standard 5060?  Any ideas?  I
believe this is where my problem sits...

Thanks,

-gcc

Make sure your using qualify=500 in the sip.conf along with nat=yes,
make sure any firewalls allow 5060 udp and tcp  and random ports above
10000 in form your PBX.

If you have all that it should work.
