cisco 2811 and FXO and FXS card

Hello folks

I just upgraded a 2811 to support voice, and added two cards, 4-FXO and 4-FXS, upgraded the IOS to 12.4(18) advanced services feature set.

however if i issue a sh run, the ports are not showing up or if i issue a show voice call summary, the ports won't show up. however if i issue a show inventory or show diag, it recognizes the 2 cards

what am I missing

thank you

You need the pvdm2-xx as mentioned above. Without it, the voice port cannot work and will not appear in configuration.

Re: cisco 2811 and FXO and FXS card

In a show run you should be seeing something like:

voice-port 1/0/0

voice-port 1/0/1

....etc.

What slots are the FXO/FXS in? They should be in an NM-HDV, NM-HDV2, NM-HD-2V or a VWIC slot.

Also, do a 'show version' and verify that you see '4 FXO, 4 FXS near the bottom of the output that shows the hardware recognized.

Verify your rommon version (although i'd expect this to be updated enough)

if i issue a sh run i don't see the

is there a way for me to confirm the slot ?

Re: cisco 2811 and FXO and FXS card

Hi, you cannot installs the voice cards on that NM.

You need to install them in the VIC slots directly in the router, and have DSP resources as well, in form of PVDM2-xx, where xx can be from 8 and up. In your case, 8 can suffice.

Hope this helps, please rate post if it does!
