FreePBX + Didww pjsip outbound trunk registration fails

[Maldoror]

I’m using FreePBX 16.0.21.9

Followed provider’s requirements to set up outbound trunk, sent requests for registration, but got warning: No response received.

Provider checked my settings and said that everything is correct, but for some reason they don’t see credentials needed for registration in my requests.

If my server had some troubles sending requests to outworld (port forwarding issues or whatever), Didww should not see my requests at all.

So, the issue is: credentials that I set in FreePBX are not included in registration requests.

That’s not how it works. The REGISTER request is sent, and then the remote side challenges for authentication. The REGISTER request is then sent again WITH credentials. The challenge is used as part of the authentication. You don’t/can’t include the credentials in the initial REGISTER request.

[Maldoror]

Yes, there are 2 requests as you said. And the second register request contains no credentials.

[jcolp (Joshua Colp)]

Those aren’t two requests. That’s the same request, retransmitted, because it’s not getting a response/challenge.

[Maldoror]

Ok, that is obviously my network problem. Although 5060 port is opened and not blocked by firewall =(

Thank you!
