Expressway x15 compatibility

[richardpierce]

I'm struggling to find this in any compatibility matrix documentation. Any help greatly appreciated. 

• Is Expressway X15.2 compatible with CUCM v14
• Is Jabber 12.8 compatible with Expressway X15.2

Expressway is backward compatible with CUCM, meaning the latest Expressway 15 works with version 14.

Jabber 12.9 is recommended as per the CSR compatibility for CSR 14. I couldn't find anything mentioned for CSR 15. I think it should work without issues; however, the recommendation is to upgrade to 14

Thank you, that's great. My end customer is looking for a Cisco reference document. Would you have reference document for the expressway backward compatibility by any chance?

Hi Maren, unfortunately, unless I'm missing something, it doesn't specifically say Expressway is backward compatible with CUCM also doesn't say that Expressway X15 is compatible with CUCM v14.

No, but there are links in there to compatibility docs for the different components.
