What are the commands needed to change an existing fractional mgcp pri only using 1-4,24 , to a full pri using 1-23,24. ?
I believe i need to first shut down the controller,
Conf t , controller t1 0/2/0, shutdown
then commands :
no pri-group timeslots 1-4,24 service mgcp
pri-group timeslots 1-23 service mgcp.
once thats done, then do command
Conf t , controller t1 0/2/0, no shutdown
Is this correct ? am i missing anything ? do i need to turn off interface Serial0/2/0:23 also ?
Thank you in advance
First of all partial PRI was never supported with MGCP, with that said your steps are accurate, plus there are service parameters on CUCM that need to be adjusted, don't recall the names out of top of my head.

The parameters are:
Change B-Channel Maintenance Status
with full PRI they should be blank, they are under service parameters -> CUCM -> Device-PRI and MGCP GW
These settings are blank. We also have 2 other full pri's terminating on this gateway.
Even the partial pri works fine, just only 4 channels and we want to use the entire pri.
