I have cisco 2811 router with VWIC-2T1/E1.

I want to configure it as voice gateway but the problem is that it is not recognizing the E1 card. If i change the IOs it recognize the E1 card but later on it is not supporting the Voice commands.

I have changed so many IOS but if one IOS recognize E1 card the same IOS not support voice command, and vice versa, please tell me which IOS support both vocie and E1 card.

I'm afraid that due to the fact the card you using (viw-2t1/e1-ran) is not a regular vwic but a special version made for SS7, there is no image that has both support for that card and voice support.
