Hi,
I am currently unable to place outbound calls, even though the trunk is registered and incoming calls work fine.
I've looked at both the asterisk and SIP debug logs and this error message comes up:
[2015-11-01 16:43:26] WARNING[4225][C-00000010]: chan_sip.c:23335 handle_response_invite: Received response: "Forbidden" from 'sip:XXXXXXXXXX@xxx.xxx.xxx.xxx;tag=as59faa608'

I suspect the cause of the problem is related to that "Forbidden" error. I've looked all over but couldn't figure out what might be the cause.
Here's the log from which the excerpt is from:
Any clue on what might be causing the issue?
Thank you.
