Hi, I´m going to migrate a Network that actually use VOFR to VOIP using this routers, 7200 VXR Routers in the Core Level, and in the distribution level the same 7200VXR and in the access level i´m going to use 3810.
So, my question is what IOS version recommend me to use in this routers?
I want to use QoS, like cRTP, etc..
