i have 2811 with PVDM2-16 and 4 ports FXO, so each port will take a channel from PVDM2-16, the remaining is PVDM2-12, I want to do HW conference resource using these PVDM2-12, is it possible to do this, since I get that not enough DSP resources when trying to create conf profile?
is it a limitation so that i can not share between termination for fxo ports and conf resource in the same PVDM2-xx module? or something else?
PVDMs have different DSP counts. PVDM2-16 has one DSP, PVDM2-32 has 2 DSPs and so on. If you wan to do hardware conferencing with DSPs you must dedicate at least one DSP for that (note the difference between a DSP and a PVDM!) or more depending the number of conferences you need to support.
In your case you should put the PVDM2-8 on PVDM slot 0 so it will be used by the FXO ports and the PVDM2-16 on slot 1 (these slots are on the PCB of the router).
The lowest PVDM I recommend you to use for conferencing is PVDM2-16 since PVDM2-8 is a low cost one DSP module and is not fully functional as the PVDM2-16.
but note that i have just only pvdm2-16 card being put in slot0, then i got from ur answer it is not possible to do conf using hw resource (conf profile) with this same pvdm2-16 card keeping in mind that fxo will use 4 channels?

The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
