Voice Gateway compatibility with CUCM version 11.5

[johnsnave1]

Hi,

I have a customer that is due to migrate their CUCM from 9.1.1 to 11.5 and has 2 x 2900 voice gateways running 15.2-4m3 ios. I have been looking for a compatibility or testbed guide but without success to see if we will need to upgrade the IOS also. The nearest I got was for 10.5.

Could anyone please point me in the right direction.

Many thanks, John.

Hi John,

Please refer the following link:

http://www.cisco.com/c/dam/en/us/td/docs/voice_ip_comm/uc_system/unified/communications/system/Compatibility/CSR-Compatibility-Matrix-InteractiveHTML.html

15.5(2)T1 is the minimum and 15.6(3)M is the recommended for 2900 routers.

Please rate and mark correct if helpful.

Regards,

Hitesh
