Hi all,
I just wanted to ask you, why my router has 2 voice cards, in the show run, look at my configuration.
voice-card 0
dspfarm
dsp services dspfarm
!
voice-card 1
!
!
voice rtp send-recv
!
voice service voip
ip address trusted list
ipv4 10.2.50.5
ipv4 10.0.0.0 255.0.0.0
ipv4 10.2.50.9
h323
modem passthrough nse codec g711ulaw
!
But, when I put, show inventory, it says that the router only have one card.

¿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
codec g729r8
codec g729br8
codec g711ulaw
codec g711alaw
codec g729ar8
codec g729abr8
maximum sessions 8
associate application SCCP
!
dspfarm profile 2 conference
codec g711ulaw
codec g711alaw
codec g729ar8
codec g729abr8
codec g729r8
codec g729br8
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.

Blank NM-HD-2VE card in slot 1 via an adapter is what creates the dsp voice card, though there are not PVDMs in it, so no need to worry about it.

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.

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..

Attached is a Q and A that helps you to understand Cisco PVDM better

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.
regards.
