New office router and firewall

I'm designing for a new office and am looking for help with which Cisco gear to order. It has to be Cisco and I just need help on the router and firewall stuff.

The new office will have two ISDN-PRI T1s. One for voice, one for data. The firewall won't be doing any VPN stuff. Just straight filtering and NAT.

I am looking at a 2811 ISR with two VWIC2-1MFT-T1/E1 interface modules. We are hoping to go to SIP in the future so I chose these for flexibility. Also looking at an ASA 5510. Will these do the trick or is that overkill?

Thanks

I think you are right on.  You could scale down to a 5505 depending on what you need from the firewall, and you could drop down to an 1800 series router, but I would prefer what you have listed.  If I was spec'ng out I would go with what you have listed, but this is without knowing how many users, phones, devices, traffic flows, etc..

ken/nas, thanks for your responses. Any idea on what interfaces I need for the router to terminate ISDN PRIs?
