What is the compatibility of SRST in the IOS 12.4 with the CUCM 7?


We plan to migrate a CUCM Cluster 4 to 7, we have 10 remote sites which have 2801 GW IOS 12.4 registred with H323 protocol. Do we need to migrate IOS of GWs before the migration of the CUCM cluser ? What is the compatibility of SRST in the IOS 12.4 with the CUCM 7?


Here is the Upgrade Matrix spreadsheet with details of all the relevant items - Compatibility, Device Defaults, Support etc. Included are current CUCM version along with 8.0(x), 7.1(3) and 7.1(2).
