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!

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