Outbound calls doesnt work.

kantor · May 13, 2019

Hi guys,

I've problem with 3cx and Outbound calls. When I'm trying to call to number 123456789 from extension 000, event log prompting this log.
Inbound calls works as charm

Hello @kantor

the log provided shows the PBX selecting an outbound rule (test) and trying to make the call. Unfortunately you are missing the rest of the log that should tell us what happens next.

Looks like the call is reaching the provider and then being rejected. I would recommend contacting your provider and ask them why the calls are being rejected.
Alternatively you could use one of our supported providers and eliminate any guess work.

But when im using e.g. zoiper and use credentials from provider, outbound calls works :/

Is there an Outbound Proxy setting (for your provider), in 3CX, that may be incorrect, or missing?

Then you can perform a wireshark capture and see how the Invite leaving Zoiper is formatted and then try to adjust the outbound parameters of the PBX to match that.
Or you could contact the provider and ask them what they are seeing wrong. They should be able to assist you to adjust the Invite.

Outbound calls doesnt work.
