So my goal is to run I think CME on 2811 with 7975 phones ( i know super vague can provide more details) just on my small home lab which includes some other switches. Would I be able to run just an internal voice network without connecting to any existing phone systems? If so where do I need to be IOS wise on the 2811 to support it currently have NM-HD-2V with VIC2-2FXO and VIC2-2FXS. If you would like any show info from the router let me know would be happy to provide and appreciate any help in the right direction!
Thanks Once again!
