Issue with Outbound SIP Calls

Hello,

I’m having an issue where I can’t make outbound SIP calls (getting 401 Unauthorized). The same phone can make internal calls with no issues and it can receive external calls. It’s only outbound dialing and I’m at a loss as to what the issue could be. A debug from a test call is below. I would be grateful for any help you could offer! Thank you!!

Jason
