Known Affected Releases

X12.5

Description (partial)

Symptom:
The first paragraph states: 
If you want MRA endpoints to be able to register multiple lines, or to share lines with other endpoints, then you must enable SIP Path headers on the Expressway-C. Due to a known issue in Unified CM 11.5(1)SU2, only enable SIP Path headers if you are running Unified CM version 11.5(1)SU3 or later (CDETS CSCvd84831 refers). 

But there is another one that has the following:

If you are using a Unified CM version before 11.5(1)SU3, and you enable SIP Path headers on Expressway-C, the following Unified CM features will report the MRA devices' IP addresses instead of the Expressway's IP address:

    Device Mobility

Conditions:
It seems that if you have a CUCM version before 11.5(SU3) and you enable SIP PATH headers you are able to see the MRA device address instead of the Expressway IP, so configuration through Device Mobility can be performed, as customer expects. 

But we previously stated that you cannot enable SIP path headers if customer don't run 11.5(1)SU3 or later
