They challenged you for authentication, and there were no credentials configured so PJSIP couldn’t re-send with them. The problem is that you are being challenged by the remote side.

Is there something I can do so the remote end doesnt challenged me?
I think its weird that via queues the calls goes through but via Dial it challenged me?

after running some test, I notice when I add it via queue.conf it goes through without a user/pass
but to get queues to work I added aors to endpoint.

queues.conf
member => PJSIP/default/sip:5555@8.8.x.x:5060,0,Explicit,PJSIP/default

Why the remote end does or does not challenge you is policy on its side. What has to happen on the Asterisk side to cause that, I do not know. Look at the signaling (pjsip set logger on) between the two and see what is the difference.

awesome, this would be a great learning example. Is there something I should be looking for? I’ve never tried debugging before. Could you point me to a documentation or possibly a tutorial or a place I can follow to know what I should be looking for?

If you prefer when I get a chance I can even post it here.

I don’t really have a guide or anything. Comparing the difference will point to the area, which may be configurable.

PJSIP base calling I didn’t do in Asteisk but issue is of authentication of SIP user at remote server.
