SIP Registration stuck at "Request Sent"

Hi All,

Registration details are ok. Sometimes the line stays up. But mostly when I’m back on Mondays, I have this problem.

Outgoing calls = OK
Incoming calls = FAILS (doesnt even go to mailbox)

Here’s what I’m getting from the log. Please advise what I can do or if any CLI commands may help out.
