Hi,

The SIP 503 is coming from CUCM. You might check the following:

The SIP trunk on CUCM is set up correctly. You need to set up a secure SIP trunk. See this doc for more info - Cisco Unified Communications Manager with Cisco Expressway (SIP Trunk) Deployment Guide
Take a look at the CUCM diags to see why it is returning that error.

hi

My cucm version 10.0.Configure a sip trunk security profile, device security mode is grey.How to enable device security mode?

I was mistaken in my above comment, secure SIP trunk is not required. Hopefully you were able to resolve the issue on your system? If so, please post the resolution.

Are your RMS licenses applied on both the Expressway-E and Expressway-C? From the 503, it appears this message is coming from the Expressway servers given the server tag "Server: TANDBERG/4130 (X8.2.2)"

How many RMS licenses do you have installed on your Expressway-E and Expressway-C?

hi

Don't have any available RMS license installed on expressway-C and expressway-E.Because in the internal network use only, need RMS license？
