Solved Outgoing

[Carty]

Hello
I have a weird problem, it's possible to receive calls without problems from zadarma numbers, but it's always error not available when maxing calls.
I also tested the SIP account directly on a yealink phone and everything was fine, so I'm more thinking it's a problem with 3CX.

Hello @Carty

Did you create an outbound rule in 3CX to allow the call out? Although Zadarma is not a supported provider I know many people are using them successfully.

 

[Carty]

Yes and I also tried with another SIP in the rule; it worked fine as well.
Could maybe one of the person using Zadarma send the configuration file I can import? I used one from another provided and modified it, maybe that could cause a problem as well.

Perhaps a user that is using them will be willing to share their config with you. Personally I do not have access to a configuration file.

More info from the Log: Call to T:Line:10005>>1111@[Dev:sip:[email protected]:5060] from L:172.1[Extn:01] failed, cause: Cause: 407 Proxy Authentication Required/INVITE from 185.45.152.174:5060

This would suggest that the authentication fails during the call. Check that you have the correct credentials on the 3CX side.

I found what the problem was, From : User Part needs to be set to "Auth ID authentication"
