debug vtsp stats
Use the debug vtsp stats EXEC command to debug periodic messages sent and received from the
digital signal processor (DSP) requesting statistical information during the call. Use the no form of
this command to disable debugging output.
[no] debug vtsp stats
Usage Guidelines
The debug vtsp stats command generates a collection of DSP statistics for generating RTP Control
Protocol (RTCP) packets and a collection of other statistical information.
