Based on the info you provided, it sounds likely that the issue lies with your D-Link router.
Did anything recently change in regards to the firmware or other settings in regard to the router?
If anything has changed in regards to the router, bear in mind that for a VoIP device to work properly behind a router, the router must "port forward" or "port trigger" on ports SIP 5060-5070 and RTP ports 16384-16482. If these SIP and RTP ports are being blocked by a router firewall, then VoIP will not work correctly...

Seeking ideas to troubleshoot a SIP registation problem.

Posted:Tue 25 of Aug, 2009 (22:50 UTC)
Greetings. I am seeking ideas to help troubleshoot a SIP registration problem. Starting a few days ago, my SPA1001 has failed to register to my VIOP provider, ViaTalk. My network connection is a single Dlink router on a Qwest DSL circuit. I have verified the SPA1001 by changing out the unit with my spare. No help there. I have verified the config... it works at another network site (and had been working for 2 years at home). ViaTalk shows no problems with my account/ID/password. Potentially I have bad router, but as the SIP registration is the only problem I am having, I don't think that is the problem. This leaves me to suspect that Qwest has made a change or actively started blocking non-Qwest SIP requests. I am seeking ideas to test, troubleshoot, and document exactly what is going wrong. Does anyone have any ideas? Are there any PD tools for this sort of debug? Has anyone used Perl:Net:SIP in debug to do something like this. I do not know much about VoIP protocols/applications, but I am no stranger to data networks, protocol analyzers, Perl, CPAN, anything UNIX, and NMS platforms and practices. Thanks in advance.
