Hi,
I am working on a Cisco 2921 router ordered with PVDM3 32 to 128 Channels factory upgrade. The DSP looks good in the inventory. However, I am not able to see / allocate all the resources available. I am unable to allocate more resources then currently are defined for Transcoding, Conferencing and MTP. Do I need to activate / license something ?

Hi Rick,
You do not need any license to activate PVDMs .U need to have Voice based IOS.
But on ISR G2 series ,in addition to Voice based IOS , also need Unified Communications license. In your case,it is alreay there since u are able to see//configure PVDMs.
Please refer this DOC by Mr. AOK
https://supportforums.cisco.com/docs/DOC-29151
Can u share the output of command show voice dsp group all.

Why are the total channels in the output of DSP Farm command equal to 24 only ?
Thanks,

Hi Rick,
It is a good catch .I have never seriously noticed in O/P but this may be due to Number of Resource Configured which sums to 24[15+5+4] .

Thanks Aman,
Yes, that may be sum of total resources configured. However, I cannot increase the individual count beyond 15, 5 and 4 without decreasing another number. The DSP config looks like this:
voice-card 0
dsp services dspfarm
....
dspfarm profile 3 transcode

If you are concern about the DSP utilization, please go ahead and check it with the DSP calculator:
