That error can mean several things, one of the most common problems is flaky
DSP's.
 
Do a "show voice dsp group all" and see if any are in a state other than
"UP".

I installed a new office a few weeks ago and I am getting occasional reports
of failed inbound and outbound calls.  On the inbound calls the ip phones
ring once and then get a busy tone.  On the router I see this message appear
within a few seconds:

 No dsps found either locally or globally! 

I have maxed out the sessions for conferencing on the router.  Could that be
the problem?
