Calls disconnecting When Dialing

[vincent Kavila]

Hello, community,

I have an issue with my outbound calls.

Every time I make an outgoing call it rings then disconnects.
When I receive incoming calls I can't hear the person speaking.

Below is the error from 3CX call
[CM102001]: Authentication failed for AuthFail Recv Req REGISTER from 192.168.1.1:55750 tid=261886415 Call-ID=635138444-1210344703-416923729:

Hi @vincent Kavila

We will need a few more details to be able to assist. What PBX version are you running? Where is it installed? Is it hosted or on premise? Do you pass the firewall checker? Who is your provider?
Any details you can provide will enable us to better assist.
