[cisco-voip] PVDMs, DSP farms, et al.... next steps?

[Nick Matthews]

You can still overprovision.

Examples:
-In the PVDM3's conferences are not reserved upon configuration.
-You are locking up G.711 (low complexity) codec, not a high complexity
codec
-Transcoding sessions are not locked upon configuration
-Video transcoding/switching sessions are not locked

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.
