I am troubleshooting a SIP trunk problem. The system is Asterisk 1.8.5.
The problem is can’t make any outbound/inbound. It always get “Number is
not valid 701″.
I tried to figure out the reason the call got dropped and couldn’t find
out the solution. I noticed that in the SIP debug there are two IP (from
the provider) involved:
It seems my Asterisk sent INVITE to the first IP, but the provider want
use 2nd one. How can I make it works? I never seen this thing before.
(BTW, if I test this account on a Linsys ATA it works just fine!)
Here is my sip.conf setting and the debug out put.
Thanks for help!
