Voice Modules for Cisco 2811 and Cisco 3845.

Hi all,

I had already posted for voice modules for cisco 2811 but  not able to find it. But here are a few questions regarding i

1. I am trying to configure a cisco 2811 with FXS ports . I am using an NM-HD-2V with a VIC3-2FXS. Please let me know if I am using the right modules. Also I believe we need PVDM mosules installed in the NM-HD-2V. We have PVDM-12 modules. Will that work or  is 2811 compatible only with PVDM2-xx modules.

2. We are also trying to configure a cisco 2811 with PRI port. We plan to use an NM-HD-2V and a VWIC-1MFT-T1/E1. Please let me know if they are correct and if we need only PVDM2-xx modules.

3. Also we are trying to configure a cisco 3845 with PRI and we plan to use the same as in 2811 that is NM-HD-2V, VWIC-1MFT-T1/E1. And here also we are not sure if we need only PVDM2-xx DSP modules.

1. ISR routers like 2811 don't need NM-HDV. Only PVDM2-xx and voice VIC.

2. as 1

3. as 1 and 2.

Thanks for the update Paolo

1. Where do I install the PVDM2 for the 2811 ? I was assuming it has to be installed on the NM-HDV. Also if no NM HDV is needed, do I inset the VIC in one of the HWIC slots?

Also, can you please let me know under what circumstances are NMHDV2 used in 2811s and 3845s?

Hi Paulo,

I installed the VIC3-4FXS on one of the HWIC ports and also installed a PVDM2 on the router board. i see both of them in sh diag , but the voice FXS interfaces are not showing up in sh ver or the sh voice port. Please let me know how to proceed.

Thanks
