<div>In my experience I have never been able to 'oversubscribe' DSP resources so that is true. I believe, and someone please correct me if I am off on this, DSPs are 'reserved' when the T1/PRI interface is turned up. So, if you had an interface configured as a 'hot' standby in case your primary PRI port goes bad, it would use DSP resources.</div>
<div> </div>
<div>Think of the consequences of being able to do overprovision. If you have conferencing, MTP, transcoding and 8 PRIs configured and all of your DSPs are in use for conference and MTP, you are going to be in trouble when people start complaining they can't make or receive calls to/from the PSTN.</div>

<div style="FONT-FAMILY:Verdana;FONT-SIZE:10pt">Thanks for this. A couple of more questions:<br><br>I read that you have to have enough DSP resources for all your voice ports (T1s in particular) and you can't overprovision. Just wondering the validity of this statement (from NetPro post) and whether this is for cards that are inserted, or turned up.<br>
<br>Also, with respect to codecs, can you configure different codecs on the same DSP? It talks about FLEX for the PVDMs, and I'm just wondering if that's the best approach.<br><br>Thanks again for everyone's help.<br>

<div style="FONT-FAMILY:Verdana;FONT-SIZE:10pt">Hi all,<br><br>I'm in the process of migrating from 6608s to 3945s. I've got all the pieces and I'm just wondering about next steps.<br><br>I've found the following documents:<br>
