Dear all,
I have one DSP (PVDM2-16) in the R2801 "12.3.11T". Can I configure HW conference and voice port (VIC2-4FXO) at the same time.
Indeed, I cannot configure as follows:
"maximum session X" under the conference profile. I only found X is "0". Can I allocate the DSP into different purposes?
Thanks for your help

Interestingly, I just had this conversation over lunch. My experience has been that even though the FXO card theroretically only needs 4 channels, it allocates all resources on that 16 channel DSP SIMM. You will need a second DSP SIMM to allocate channels for conferencing, transcoding, etc.

Another problem with this config is that the PVDM2-16 is only 1 dsp, and conferencing requires a reserved dsp:
PVDM2-16 16-Channel Packet Fax/Voice DSP Module
1 DSP (TI 2510)
Q. Can conferencing share the resources with transcoding or voice calls of a single DSP?
A. No. Conferencing needs a dedicated DSP resource. If a DSP is assigned for a conferencing session, then it cannot be used for transcoding or voice call initiations or terminations. Transcoding and voice calls can share the resource of a single DSP, however. Note that conferencing needs a dedicated DSP, but not a dedicated PVDM2 module. For example, PVDM2-64 contains 4 DSPs; if one of them is used for conferencing, the other three can still be used for other purposes.

I have one question and wondering how to configure PVDM2-64 to share DSPs though.
"PVDM2-64 contains 4 DSPs; if one of them is used for conferencing, the other three can still be used for other purposes"
I'd really appreciate if anybody could point any documents so a single PVDM2-64 can be shared for both Conferencing and voice termination. thanks, Veera
