Differences betwin Cisco Voice Cards

Hi,

I have a Media Gateway that is certificated to work with Cisco 2650XM using NM-HDV-1E1-30E or NM-HDV-2E1-60 cards to make trunk TDM and cisco work as ARU (Automatic response Unit) using TCL 2.0.

Now, i have a cisco 2811 and seen VWIC-2MFT-E1 and VWIC-2MFT-G703 cards, that are more cheap than that the NM cards.

My question is if can I use this VWIC to replace that NM voice cards for applications of ARU (Automatic response Unit) using TCL 2.0.

Thanks.

Fred

You need to use show voice dsp all. This will show all dsps. The show voice dsp only shows allocated dsps and depending on your configuration or whats in the router then this might not show anything.

Also show inventory will show a PVDM2 and the type (ex PVDM2-64)

Please rate any helpful posts

Thanks

The VWIC-2MFT-E1 card will work, but you will still need DSP modules in the 2811 to handle the voice processing. The type of PVDM2 DSP module you install will determine how many channels and the type of codec used on the gateway.

Also here is a good document on the DSPs for your router.
