Cisco 2921 PVDM3 Resources

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 ?

Cisco 2921 PVDM3 Resources

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 ?

Re: Cisco 2921 PVDM3 Resources

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] .

regds,

Re: Cisco 2921 PVDM3 Resources

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

description XCODE Resources

codec g729r8

codec g711ulaw

codec g711alaw

codec g729ar8

codec g729abr8

maximum sessions 15

associate application SCCP

!

dspfarm profile 2 conference

description Conference Resouces

codec g711ulaw

codec g711alaw

codec g729ar8

codec g729abr8

!

dspfarm profile 1 mtp

description MTP Resources

Thanks,

Rick.
