Remember you also need PVDM2 that is the required DSP resources, to use router for VoIP. Do "show diag" to know if you have it and what "size" it is.
Hope this helps, please rate post if it does!

The 2800 Series ISR gateway certainly support voice, take a look at the document at the following link it refers to the various gateways interoperability with CallManager:-

And once you get the router set up, go get the E1 Pri debug demo from pippinsoftware.com , it's handy for troubleshooting.
