Outbound not working 603 declined

[smokie]

Hello

I am in need of help please, I have setup a test environment and I am running v16 on a windows10 box.I am using a Sip Registration account, Problem that I am experiencing is that inbound calls are working but outbound it fails with a 603 Declined, I am not sure if I am sending them the wrong details in the sdp header or something, i have attached wireshark trace, please advise as my Sip knowledge is not good at all, Thanks

Hi @smokie

You will need to provide more information about your setup

• What trunk are you using (or gateway)?
• Is there an external DID that your PBX can be reached at?
• Can you not make any calls at all or did you only try one destination?
• Is this some pay-as-you-go trunk that requires credit before you make outgoing calls?

The trace only shows that you reached the "provider" successfully but the call was declined for any reason that lies beyond the PBX and can likely be answered by the trunk provider.

Hi

Trunk - sip registration trunk to my Provider
Yes - there is
Cannot make out any calls, local, national, mobile, international
Nope - pay rental fees every month

Ok since the decline appears to be coming from the provider side, it might be worth giving them a call so they can inform you why. Perhaps there is some restriction you are not aware of on this account

Thought as much, thanks I appreciate it.
