Another puzzler from my asterisk system: For reference, here is my basic setup: -Asterisk (latest CVS as of this afternoon (3/19/2003) -All clients are Cisco ATA 186 units -Public IP for Asterisk server -All clients behind NAT firewalls
Everything was working fine with my Asterisk system until I added a client behind a firewall that has three numbers in the final octet of its public IP number. For instance: A client behind a firewall with public IP of 63.77.102.4 would be fine A client behind a firewall with public IP of 63.77.102.221 would fail The failure does not present itself until an INVITE is issued (registration works fine). When the INVITE happens to or from such an IP, though, Asterisk segfaults. After studying the output of sip debug, I noticed that somehow the Contact: field is getting messed up. The field should look like: Contact: <sip:[EMAIL PROTECTED]:5060;user=phone;transport=udp> Instead, it looks like: Contact: <sip:[EMAIL PROTECTED]:5060;user=phone;transport=udp> I checked the settings in the ATA, and they are all correct, with no reference whatsoever to '63.91.19.0'. The ATA is on the same firmware as all of my working units. I can only assume that Asterisk is somehow losing that last octet when it deals with a NAT client behind a firewall which has a three-digit number at the end. Does this seem accurate, or am I missing something here? I have attached an excerpt of sip debug output showing this problem (line 22). Any suggestions that anyone could offer for troubleshooting/fixing this problem would be greatly appreciated. Thanks! -Matt -- Matthew Farley <[EMAIL PROTECTED]>
