Solved Call from phone on one SBC to a phone on another fails

[architechture]

I have a user that works from home and have them setup with an SBC and a Yealink T46. They can't call just one extension that is on another SBC (previously they couldn't call them when the PBX was in-house and that extension was connecting to the PBX directly). I've tried everything I can think of. Any advice on what you would try to do to resolve this?

I haven't had her factory reset yet, so that's next.

Factory reset solved the issue.

I'm glad to hear

This makes it almost certain that the phone was rejecting the call, with blacklisting being the most probable candidate.

If it happens again be sure to inspect the phone to confirm.
