TA908e SBC, SIP calls failing

I have a TA908e that I have had running for about a year now. All of a sudden SIP calls in both directions are failing.

When I run the show voice call summary active I see the calls hit the ADTRAN. When calling from the outside in I hear one ring and then the line drops. Any Ideas on what would cause this? A reboot did not fix it and it has happened two days in a row now. Nothing has changed in the config on this router since it was installed.

Re: TA908e SBC, SIP calls failing

something major must have changed for calls to drop in both directions. Have you verified that your SIP service hasn't been turned off?

verify trunk registration

show sip trunk-registration

SSh or telnet into your unit and enter the following debug and then place an outbound call, put that debug in one text file, then place an inbound call and put that debug into another text file and then attach them to your reply.

debug sip stack messages

debug voice verbose

debug sip cldu

debug hmr

Thanks,

Mark
