8831 won't register to CME - SIP CONTACT issue?

I have 3x Cisco 8831 conference phones which have worked on our CME for around 2 years now. But last week I noticed all 3 are showing "phone not registered".

 

Checking debugs I see:

To me it looks like the SIP Contact header is what is causing the issue?

 

If anymore debugs/information is needed I can collect these tomorrow morning.

Re: 8831 won't register to CME - SIP CONTACT issue?

What hardware platform?

What version of CME / IOS?

What version of phone firmware?

Can you post a sanitized show run (specifically, the voice service voip and global register sections)?

Hope this helps,

Ryan
