Issue making outbound calls

General Help

1

ive been trying to make outbound calls with freepbx and have tried troubleshooting myself for over 2 days now just to end up no where, everytime i make an outbound call using any softphone it calls for a couple of seconds and disconnects, my IAX2 trunk says unmonitored instead of online so i swapped to pjsip but still no luck
here are some of the logs:

Hi ! When you say “it calls”, you mean it connects the call and then drops?
If so, could be a NAT issue.
Is it happening only with softphones and all of them are outside your pbx network ?

3

the call connects but nothing’s happening to the number i call, no rings, nothing, and when i used zoiper instead of linphone it says the error 408 call rejected.

4

408 is timed out, not rejected. It normally means there is a network configuration error which means either the request, or its response, never reach their destination.

5

would you happen to know how i can fix this or how i can troubleshoot this issue please?

You capture packets at various places in the network until you find where they get lost. You also check that they are being sent to the right addresses. You fix any wrong address, then looks at the configuration of routers and firewalls around the point of loss.

Basically you have a symptom. You have to find the cause, and fix that cause. There are rarely easy answers where the correction for a message is obvious and precise, and in most such cases, the answer is in the message.

I’ve described the more common case, where the 408 is faked, at the sending end. It can also be generated by the remote end, and for internal time outs, there.
