I'm trying to set up a VIC-2FXS on a 1760 using MGCP and the documentation I'm following tells me to enter "ccm-manager config server <ip addr>" in global configuration. However when I attempt I get an invalid input marker at the second "c" in the command. Entering "cc?" gives me an "Unrecognized command" message. IOS version on this router is "C1700 Software (C1700-IPVOICE-M), Version 12.3(22)". Thanks in advance for any help.
Although MGCP is supported in IP Voice main IOS Train 12.3(34), MGCP Gateway support for CallManager is actually supported in ED release 12.3(14)T7 not main-line, with the exception of only 12.3(11)YZ2 and 12.3(11)XL1.
Unfortunately the minimum amount of DRAM required for 12.3(14)T7 and 12.3(11)YZ2 is 96Mb and 32Mb Flash. 12.3(11)XL1 requires 128Mb DRAM and 64Mb Flash. I would be inclind to opt for the T train release.
MGCP Gateway support for CallManager is also support in the following 12.4 releases:
12.4(6)XT, 12.4(4)XC7, 12.4(2)XA, and 12.4(15)T1 all which require 128Mb DRAM and 32Mb Flash, whereas the mainline train 12.4(17) requires only 96Mb DRAM and 32Mb Flash.
