We spent a lot of time in debugging and troubleshooting DSP issue. Recently, I used this DSP test (a hidden one yes) command and it gave me immediately result that the DSP on the router has gone alley and as a result the calls from one location to another one were having issue.

This handy tool has been tested on ISR modules.
