I have cisco 2811 with 12.4(11)SW3. Earlier I have the IOS (C2800NM-IPVOICE-M), Version 12.4(18)
but it was not recognizing the E1 card, but i was able to confiugre it as voice gateway with this IOS, after the 12.4(11)SW3. I am able to detect the card but now it is not supporting the voice commands.
I am not able to make the dial-peer etc. I wanted to configure it as voice gateway. Kindly tell me which IOS will support both the E1 card and voice commands.
