CM Telecom return 403 every time on outbound calls.

anybody using Cm telecom?

How to do make call?

Inbound calls works but i dial any number on softphone instantly rejected and return 403.

I think the best thing you can do is contact the provider and ask them why they are replying with 403. If they give you a hint and it has something to do with the PBX, then maybe we could help.

I asked and no response for 3 hours but i think need change outbound parameters.

Are you certain that you should be sending the number wth a leading +, and not a zero, or some other prefix?

i tried every format but nothing.

Well, this https://www.3cx.com/docs/cm-com-sip-trunk/ does seem to indicate that you are sending the numbers correctly, so there may be another setting that is incorrect. To save yourself the time of just guessing and changing random settings, I would await a response from the provider, about what they see, as being incorrect.

You are right i tried everything but not working.
