[Asterisk-Users] SIP INVITEs borked with iconnecthere

[John Todd]

Symptoms: when calling my iconnect phone number (13033913323 in my 
bogus example below) from my cell phone, I can see that the call 
makes it to my asterisk server, and my phones even ring once as * 
passes the call through during the "180 Ringing" period.  However, it 
seems that iconnecthere.com cannot see my "100 Trying" and "180 
Ringing" messages, as they continue to send INVITES to me.  After two 
seconds, they either give up or error out and send a CANCEL message.

To further increase my suspicions of something weird in the ability 
to "see" my replies, they send 11 CANCEL messages over the period of 
30 seconds, despite my "200 OK" replies.


Notes: 204.31.11.32 resolves to asterisk.something.com.  204.31.11.35 
is my ATA-186.  Neither the domains nor the IP addresses are real, 
except when referencing iconnect servers.

213.137.73.176 is the real IP address of the SIP proxy at 
iconnecthere.com (deltathree.com)
Note that I actually do my REGISTERs against 213.137.73.178, not .176 
- not a big deal, but who knows what clues will be helpful.
