[cisco-voip] DSP and voice resources...

[Luis Mata]

Ryan:

   Thank you for your reply, So, if this is the case how do I upgrade to
96 Voice resources, since both slots happen to have DSP cards in it?. Or
is it something with the Flash?.

Try configuring two of the T1's as CAS and then do 'sh voic dsp group all' and you should see the shared vs signaling resources.  If you try to configure the 3rd T1 as CAS or PRI, you should get an error.
