dial plan question

I've got a 4224 running ios 12.1(5)YE1.

I am routing the patterns '911' and '411' through fxo ports. I also want to route '9911' and '9411' through the same ports. With Call Manager running, this isn't a problem. CM simply strips the 9 and sends the call to the gateway. However, if the 4224 is running in SRST and has no connectivity to the call manager, I have a problem. The call manager cannot strip the 9 and the call is lost.

I cannot have the gateway strip the 9 because it only strips specified digits. Alternatively, if I specify '9...' all long distance outbound calls they make will be sent to 911, the first number matched. (They prepend all outbound calls with a 9).

Does anybody have a solution? Surely someone has run into this.

For further clarification, here are the relevant dial peers:

Re: dial plan question

Sounds like an application for number expansion to me. e.g. num-exp 9911 911

This is applied before it hots the dial peer, so your existing peers will pick up 911 or 411 on yur dial-peers 300 and 302
