I have Asterisk 18 installed on ubuntu 22.04. I configured my pjsip.conf and extensions.conf files using the instructions included here.
I get notified by asterisk CLI when 6001 registers and is “available” so clearly the softphone (Zoiper) is talking to the asterisk server, but, when I attempt an outbound call, I get an error which doesn’t seem so helpful that states “Everyone is busy”.
Can any experts look over the settings provided in the link above and make an educated guess what might be happening? Or perhaps, point me in the right direction to troubleshoot it better?
SIP debug output:
