wondering if anyone can help ?.

trying to add the following command to my E1 controller on the above router and I get the following error message

CHPFXW01(config-controller)# pri-group timeslots 1-31 service mgcp

% Not enough DSP resources available to configure pri-group on controller E1 0/1/0

% The remaining dsp resources are enough for 0 time slots.

% For current codec complexity, 2 extra dsp(s) are required to create this voice port.

How do I add extra DSP's .....this isnt my field so i am a little lost.

DSPs are hardware resources required for processing voice (digital signal processor). You will need to purchase the DSPs from Cisco and physically add them to the router. I believe you need a single DSP per channel on a voice E-1. Since you are attempting to add 31 channels you will need 31 DSPs.
