<font style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">Basic stuff, but I haven't found the definitive answer yet. If I have one PRI but using only 10 channels (and H323), with one PVDM3-16 is enough? Is it the same for MGCP?<br>
<br>
Thanks!</font><br>

Take the simplest example - PVDM3-16 on a partial PRI.<br>
<br>
The 16 channels will be allocated to the PRIs, but as soon as one of those calls is G.729 you won't be able to get 16 calls through.<br>
<br>
I haven't played with the allocation on the PVDM3's as much as in the back end it's a lot more complex than the 2's.<br>

<div class="gmail_extra">Could you clarify your point of being able to over provision here? From my experience, as you add sessions to one service, it dynamically reduces the available sessions on the other services.</div>
<div class="gmail_extra"><br>
</div>
<div class="gmail_extra">I.e., If you do a ? on sessions for transcoding, it might say <1-40>. But if you go and add a few more conferencing sessions first, and come back, it will be lower. Say <1-32>. I'm making these numbers up, but the fact remains, the
maximum number you can type in, is limited by the available resources at config time.</div>

<div class="gmail_extra">You can still overprovision.<br>
<br>
Examples:<br>
-In the PVDM3's conferences are not reserved upon configuration.<br>
-You are locking up G.711 (low complexity) codec, not a high complexity codec<br>
-Transcoding sessions are not locked upon configuration<br>
-Video transcoding/switching sessions are not locked<br>
<br>
So if you're using non G711 codecs, transcoding, conferencing, MTPs, or video, you can overprovision. If all you're doing is G711 termination to POTS/PRI I don't think you can.<span><font color="#888888"><br>

<div>Once you build the channels on the controller "pri-group timeslots 1-24" the DSP resources are locked, FXS and FXO lock on bootup.
<div><br>
</div>
<div>I think that command you're looking at will show you what you want, you can see the transcoding towards the bottom</div>
