How to harvest PVDM's

I currently have a 2801 router with the following modifications

DWR_Unity#sho inv
NAME: "chassis", DESCR: "2801 chassis"
PID: CISCO2801         , VID: V04 , SN: FTX1137W12N

NAME: "WIC/VIC/HWIC 3", DESCR: "2nd generation two port FXS voice interface daug
htercard"
PID: VIC2-2FXS         , VID: V01 , SN: FOC12033REB

NAME: "PVDM 1", DESCR: "PVDMII DSP SIMM with one DSP"
PID: PVDM2-16          , VID: V01 , SN: FOC13512D4F

NAME: "AIM Service Engine 0", DESCR: "AIM Service Engine"
PID: AIM-CUE           , VID: V01 , SN: FOC10061FMD

When I modify the voice-card and enter "maximum sessions?" I get an output of "<0-0>.

Is this using the DSP's "built in" to the router?

How can I utilize the PVDM I have installed? I am trying to set up an IOS based conference bridge for testing purposes

Re: How to harvest PVDM's

DSPs only exist in PVDM modules. No ISR router has any modules "built in" (i.e. soddered to the mainboard.)

Yes you can transcode a few calls using the same PVDM-16. Use the calculator; it will tell you exactly what you can do.

You need at least a PVDM2-32 or a second PDVM2-16 to do conferencing. A PVDM2-16 has only a single DSP on it and this cannot be multipurposed for both termination of the analog ports and conferencing. You can use the DSP Calculator to validate any DSP configuration.

I thought the 28XX's had built in DSP resources and could act as a conference bridge.

What services can I run with my current configuration? Will I be able to transcode one codec from g.711 to G.729?
