Jabber MRA and Jabber Guest on same Expressway C+E pair. Design question

[tknapp]

Customer currently has a pair of Expressways (C+E) running MRA.  The expressway code is 8.9.1

Call Manager is running 11.5.  Customer now wants to support Jabber Guest Services.  Since the customer is running 8.9.x on Expressways do they still need to get another set of Expressways for Jabber Guest to function?  I saw on some road map/power point that future Jabber Guest and MRA was to be hosted on same Expressway Pair.

Thank you.

Yes, separate Expressway-C/-E pairs are still required for Jabber Guest vs. MRA. The config guides for both state this unambiguously:

Thank you for the fast response.  Just wanted to be sure I did not miss some release notes or updates.
