Expressway compatability

[Paul Austin]

Hi All, Need some advice regarding expressway compatibility with CUCM version 10.5. Yes I know the version is old and needs upgrading but the customer is not in a position to do so just now but does require MRA. The matrix says minimum is 8.1, recommended 8.2 but has anyone had 12.5 working with CUCM V10.5 or know a definite answer as Cisco themselves are saying different things?

Many Thanks

Paul

Hi,

This is the exp version

X12.5.7
For CUCM, we completed the upgrade later and I don't recall the actual
version number and what update it was on.

Hi Mohammed, So just to confirm. Expressways was already version 12.5 and working before you upgraded CUCM from version 10.X?

Sorry for asking but its really critical for me.

Thanks

Yes. it is working. MRA is straight forward sip/http integration. There is
no reason not to work.

This is already covered in the documentation

https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/expressway/config_guide/X12-5/exwy_b_mra-expressway-deployment-guide/exwy_b_mra-expressway-deployment-guide_chapter_0100.html

Special attention to the APNS minimum requirements if you are going to use Apple devices over MRA.
