I don't believe "channels" in a dsp (pvdm) and a pri are the same. A pri has 23 channels plus 1 for control. In testing I've done with pvdm modules each "channel" is used by each participant not just for each call. So, a pvdm2-16 using only g711 will get you 8 calls.

Actually, thanks for making me double check. There are only 16-channels enabled on the PRI going to the Avaya. Punching that into the DPS calculator gave me this:
Optimized Result(Default)
1 DSP(s).
one PVDM2-16
CLI Info <javascript:show_result(1)>
Normal Result
2 DSP(s).
one PVDM2-32
or
two PVDM2-16
I guess I’m “ok” with the optimized result. I notice the normal result mentions more DSPs. With the suggestion it made, shouldn’t optimized be the one with 2 DSPs?

How many channels on that PRI are you going to bring up or are you looking to do a full PRI to your avaya?

Yeah,
Mike just sent me the link to that. It mentioned that the “normal result” would be 1 DSP (PVDM2-8). There are only 9 people in the branch office, hence why I think the PVDM2-16 would be ok.

You can always use the dsp calculator on cco just to be safe.

Thanks Mike. This is what it returns for the remote branch router:
PVDM Slot 0:
16-channel (G.711) Voice/Fax PVDMII DSP SIMM PVDM daughter card
I can verify that this is ok because our router in our office has:
PVDM Slot 0:
64-channel (G.711) Voice/Fax PVDMII DSP SIMM PVDM daughter card
So I’m set just to replace that HWIC card with a VWIC?

Do “show diag” and look for what is in the PVDM slots. Or, physically open the router and look for what is in the PVDM slots.

ARG.. I had the feeling it was the wrong card… but wanted to verify with other experts before I raised a hullabaloo.
Thanks Mike.
P.S. – How do I know if a DSP was included in my bundle?

HWIC is for data, not voice. As for whether or not they shipped you the wrong card, that depends on what you ordered. ;-)
Don’t forget you will need DSP as well, unless the router was purchased as a bundle that came with it.

Subject: [cisco-voip] Voice Router - PRI Card Compatibility
I'm not too keen on my VoIP terminology, so please excuse me if you get confused...
My company recently purchased a C2811 router for a VoIP deployment at a branch office. Currently they are using PRI to connect to their analog (Avaya) phone system. I am to remove their analog system entirely and replace it with a Cisco VoIP solution.
While I have never actually installed a Cisco VoIP system from scratch, I have maintained the one at my current office. I have most of the configuration finished on the router, but I cannot specify the voice ports on the new C2811 router. The PRI that is used at the remote office is the same type that is used in my current office.
After a couple hours of troubleshooting, I came to the realization that the card that is currently in use at my office is a "VWIC2-2MFT-T1/E1". The card that came with my voice router for the remote branch is a "HWIC-1DSU-T1". Is this the reason why I cannot configure my voice ports? Did they ship me the wrong card?
Thanks in advance.
