Most cases, the best practice is to reset the box or
controller for dsp reset but you can use this
few methods too.
1. go unto the voice-port and do a shutdown, no shutdown.
this will reset the dsp used by that particular voice port
2.go to the voice port and do a busyout forced and no busyout forced.
This too will reset the dsp per voice-port
3.go under the controller for cas trunks and do
ds0 busyout 1-24 & no ds0 busyout 1-24, this will rest the dsp based on the timeslot
specified.
