Ahmed,
The Expressway cluster (C or E) can have 6 member nodes (1 primary and 5
subordinate peer nodes). Here is the clustering guide for 8.7 (but all versions
have an equivalent guide):
Thanks James,
One more point if you please, what about Expressway HA setup? How many EXP-C
and EXP-E servers can be in one setup? And could the HA units reside over the

parameter checked, but make sure it is only checked in one cluster. Also,
you have to make sure you are using ILS and have peer links in IM between
Hi Gents,
If we have 4 standalone clusters each of them has its own CUCM and IM servers
(version 11.5), I'd like to know if it's possible to have only 1 Expressway C
and E system to serve all the 4 cluster with MRA service ?
Taking into consideration that all the 4 clusters are using the same
