Voice and Dialup on the same PRI?

I have a 3661 with a PRI port that connects to the LEC to provide voice in and out for my Call Manager. I also have another 3661 with an NM-8BU and 6 mica modems. Is it possible to allow analog modems to dialup through the PRI to the mica modems without dedicating the whole PRI for dialup? I would like to get rid of my BRIs and dedicate a phone number or two on the PRI for occasional dialup access by travelers.

Re: Voice and Dialup on the same PRI?

No way to have voice and data on the same T1/PRI on a 3600 router. 3600 will not be able to punt the call to internal mica modems which are not DSP's.

You need to have two PRI lines one for data and one for voice so that calls will be routed approoriately based on the line it is received.

If you have AS5400 with Nextport digital modems which are DSP's too, its possible.

OK. That's what I thought. Thanks.
