Effective Gamma Template to allow International Calling

[Alex Nicol]

Hi All

Do any of the Collective have a setup as below and if so, would they be willing to share their settings?

Gamma SIP Trunk
Azure Hosted 3CX
Enterprise Edition V18.0 Update 8
Able to call Netherlands without getting 400 NOT Found Errors.

Further Notes:-
Yes International calling is enabled on the SIP
Yes, the Netherlands is an Allowed Destination on the 3CX
Yes the number is good, I checked on a different 3CX system and a mobile
I have another 3CX system using a JOLA SIP and can call the Netherlands without issue.
Yes I've contacted Gamma support, and they are being very helpful, but it's piecemeal - try this, try that, change this. etc.

I'm hoping that someone here has an already fully working system that I can exchange Outbound SIP settings with.

Kindest Regards

Alex Nicol

We have some Gamma Trunks in use (Germany). Maybe this helps...

This 404 is coming from Gamma... Please adjust your outgoing rules likes this (with your country code):
