Outbound call not working

[Aouko]

Hi everyone,

We have setup the 3CX phone system and everythings works well, extension, inbound calls, IVR , etc...

But we cannot make any outbound call and we cannot find why.

Our number supplier is VOIP.MS, if it is necessary.

Hope you can help !

good day everyone

im a newbie in voip setup and 3cx. My 3cx can't make outbound calls. but inboundcalls are okay and it had good audio conversation. I don't know why outbound calls did not work. I checked the firewall checker and this is what it showed.I guess the problem is the port forward but I don't have idea on how to configure that thing. thanks in advance for the help

Until everything in firewall checker is green, You should work on Your firewall. What kind of firewall do you have?

That is a good point, but where the hell do I change that parameter ?

It depends on the Providers Host as far as I know. For me it was so.
Who is Your provider?

The Provider is VOIP.MS

A 3CX log of an outgoing call, and not just one or two lines, the full call from start to finish, would be helpful. You can X out part of any public IP, or phone number, shown in the logs,

Hello @Aouko

The issue now is that there is no audio when making outbound calls, correct? What phones are you using to place these calls? Can you replicate the issue with a 3CX client?
Also try using a supported provider to see if you can replicate the issue. There are a few that offer a free account for testing.
