We plan on upgrading our CUCM cluster to version 7.1(3b)SU2 from version 6.1(4).
We currently run 1760 voice gateways with the IOS: ‘c1700-ipvoicek9-mz.124-15.T9.bin’ (12.4T range).
I wanted to establish if the latest version of this IOS would be good enough for CUCM7.1(3b)SU2:
Latest 124.T IOS: c1700-ipvoicek9-mz.124-15.T13.bin Release: April 2010.
Any advice would be appreciated.
