I want to add a Cisco 888 gateway using MGCP in CUCM version 18.104.22.1684-1, this type of Gateway is not there to add, is there an update I can apply to CUCM to be make this Gateway available to do this?
According to the following link, you need a minimum of 6.1(3), 7.0(2) or 7.1(3).
Hope this helps.
Found this in a SRST document - implies support starts at 6.13
SRST 880 is natively supported by CUCM 6.13 and 7.1
