I had a 2811 die on me (boot failure - won't come out of rommon). I swapped it out with another 2811 we had in stock, and moved the FXO card from the old one to the new one.
I copied over the same IOS and config the old one was using as well.
Everything came up fine, except outside dialing. I can't seem to configure the voice card.
conf t and then voice-card 0 returns "invalid input" at the 0. That's definitely the slot the card is in, and I've tried the other slots, and the same thing happens.
I'm not the normal Cisco guy here, he's on vacation so I'm hoping someone can help. thanks!
