You need to provide a sh run to see what you have configured and what might be the error.

Add an output for "show voice dsp group all" and "show voice dsp error".

Your DSP cores are in a failed state. Reboot the router and see if the state changes to an UP. If not, you would need to replace the PVDM's.

I ran across this thread because one of the sites I support had this same issue. I was getting DSP Timeout errors and we reloaded the router and the DSP's came up in a FAIL STATE.

I then powered off the router (2951) completely and unplugged the cable. Waited a few minutes and powered back on and everything worked. I believe the PVDM's are going bad and I need to replace them but this bought me some time.
