HI Pros,
I need help to configure a T1 line for voice in Cisco 2801 router.I have the card installed, whenever i try to install the pri-group, the router displays the following errors message
1. Please configure Network clock participate wic 3 first.
2. Insufficient resources to create pri-group, it has been removed.
Any help will be much appreciate and in advance,

I do have 16. Is that enough to enable all the 24 channels of the T1?

ok, do you mean 16 DSPs??
or 16 channels??
the PRI needs 1 channel per DS0. so 24 channels for a full PRI.

NOp, I mean that I have 2 DSPs for 16 voice resources. Is that enough DSP for a full t1 or can I just enable up to 14 channel for the t1?

ok, 1 DSP = 16 channels
so either you have 1 DSP which means 16 channels, or 2 8PDVMs which are half DSPs.
if you have 2 DSPs then that's 32 channels
in any case, a T1 as i already mentioned requires 1 channel per DS0. so 24 channels required, if you have 16 you cannot use the full T1.

This error is a little confusing, because the error in #1 is what #2 is complaining about. You'll get a different error when you don't have enough DSPs...I think it actually says you don't have enough DSPs..
Following is the config for the clocking:
network-clock-participate wic 3
network-clock-select 1 T1 0/3/0
isdn switch-type primary-ni
controller T1 0/3/0
framing esf
linecode b8zs
pri-group timeslots 1-24 service mgcp
exit
Good luck!
