If you don’t have enough PVDM capacity, you can’t configure all of the channels
on the PRI or all of the POTS lines. There is a DSP/PVDM calculator on
Cisco’s website that will tell you how much you need for a particular
configuration. Based on your symptom description, I’m not sure that this
is your problem but never say never.<br>

<p class=MsoNormal><span style='font-size:9.0pt;font-family:"Verdana","sans-serif"'>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.<br>
<br>
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.<br>
<br>
Any ideas?<br>
