ANI and DNIS over a T1

I am trying to route incoming 800 calls over a T1 connecting to a 3640 router to a Call Manager. The 800 number calls come in with a 4 digit tag such as 7405. My problem is what shows up in the called number field is *2125551212*7405*. This is basically the caller ID information and then the 4 digits sent to allow us to route the call. The problem is that the router sees it as all the called number. What am I doing wrong?

I am using a typical

ds0-group 0 timeslots 1-24 e&m-winkstart dtmf dnis command.

Any help would be appreciated...

Re: ANI and DNIS over a T1

Not sure if its same for 3640 also, but I do have a link for AS5840 explaining the config for T1 CAS for VOiP. This also includes the ds0-group 0 command in it.
