I am trying to add a 2911 Voice Gateway to a Call Manager 5.1.2 as a MGCP Gateway. The 2911 is not an option to add. What version of 5 do I need to go to have the 2900 series routers available?
There is no 5.X version that supports ISR G2s as MGCP, the minimum you need is 6.1(5).
If this helps, please rate
