How do I get around this problem? The voice interface and controller are shut down, I've rebooted, etc.
MIA-2811(config)#controller t1 0/2/0
MIA-2811(config-controller)#pri-group timeslots 1-14,24
%Voice interface must be shutdown before updating configuration.
did you try
no pri-group timeslots ..... for your existing config.
paste your whole configs.
We had a similiar problem in a Controller where it was not allowing us to assing timeslots 1-24 and it said we needed to shut it down. Turned out we did not have enough DSP Resources.
I called TAC;
The voice-port was not shutdown -jason
