I just wanted to ask you, why my router has 2 voice cards, in the show run, look at my configuration.
dsp services dspfarm
voice rtp send-recv
voice service voip
ip address trusted list

¿am I wasting DSP resources by not using that "phantom" card?
I am using that DSP for the following configuration.
2 E1 DS0 voice link configuration (60) channels.
dspfarm profile 1 transcode
maximum sessions 8
associate application SCCP
dspfarm profile 2 conference
maximum sessions 4
associate application SCCP
What I meant to ask you, is...
do I only have 1 DSP card?
do that DSP card is the only card I need to perfectly fit my configuration?
I've read about DSP, but I only know fundamentals. I do not know very much the meaning on my router configuration. I just had a router with a similar configuration, copy/pasted it, and then in works.
Solved! Go to Solution.
Your High Density Voice Card has PVDM's on it. They are most likely PVDM2's and you'll have some limitations using them in the same pool as your PVDM3's.
EDIT: Read through your inventory too fast. If you had PVDMs on your module, they woulod be PVDM2's.

YOu only have one DSP , PVDM3-192 which is on slot0, Kindly find the below link.
please rate if this will help you
On the DSP side of things, you have a PVDM3-192. This PVDM has a total of 5 dsps in it. It is a combination of a single PVDM3-128 and PVDM3-64.
Each PVDM3-128 has 3 dsps and each PVDM3-64 has 2 dsps..Hence giving you a total of 5 dsps..
You can read more on PVDM2 and PVDM3 credit allocations here..

Hi Cris, I didn't realize I had a Voice Card withput DSP, I didnt realice a NM could create a "Voice Card conf" even without a PVDM on it.
Well that was what I understood, also i'll check the links posted on this thread.
Thank you all of you for your time, your help is very useful.
