Hi,
We are going to upgrade ios in 3925 SRST enabled voice gateway from 15.0(1)M6 to 15.1(1)T because the existing ios does not supports 69XX IP Phones in SRST mode .
We have CUCM 7.1.3 , Unity 7.0 and CUE 8.6 in our setup.
Whether the new IOS 15.1.(1)T is compatible with CUE 8.6 and CUCM 7.1.3 or not?
Does the new ios has any bug list?
Please also help in posting a cisco document for IOS Upgrade.
Regards
Ankita Vig
