[cisco-voip] PVDM

What specifically happens (or can go wrong) when you do not have enough
DSPs on your PVDM module for a VoIP deployment?  Like for instance, if
you have about 24 phones + 1 VG204 and you used a C2811 router with (1)
PVDM2-16 and (1) VWIC2-1MFT-T1/E1.

 

I'm curious to know if the PVDM2-16 is my problem.  I converted an
office earlier this week to Cisco VoIP with the above equipment.
However, I'm finding that while outbound calls can be made (not sure how
many simultaneously), I'm having a problem of people dialing in and
getting a message saying that the call could not be completed or is
disconnected.  I did not change any of the phone numbers and the number
pool is the same.  The problem is random.  It occurs on some phones,
then goes away.

 

Any ideas?
