403 Forbidden error

[jbob101]

Hi All,

Ive just setup my 1st 3CX server using v20. Ive setup the trunk and outbound rules. inbound calls are working fantastically but outbound calls are not working at all. when i dial out i hear "Call forbidden by administrator". upon checking my logs i see the below 403 forbidden error. Ive called my SIP Provider (Exetel) and they stated everything is working from their end, they also said that the issue myst be from 3CX? any help would be appreciated

I just had the same issue after re-building our trunk registrations (due to the dropping of template by the upgrade from v18 to v20).
By trial and error, I discovered I had to put our number into the Outbound Caller ID field of the Outbound rule for that trunk.
