Dial up router purchase

Hi,
Yeah that's right I need router that will dial up to an ISP allowing users to share access through it. It is a small office-They can't get DSL(not yet atleast) can't get cable. As a matter of fact dial up is what they want.
Is there a good router with firewall capabilities that will do this?
I know of one that does this and it actually provides email as well (what it does is has mailboxes on it and then it goes to the ISP and downloads each persons email to the appropriate mailbox). Then at the person's workstation they have it configured to get internet mail from it. So in IP address you put the address of the router (which is the gateway) and it will go and download the appropriate mail. This device is pretty expensive so I was wondering if there were alternatives.
Thanks for any advice.

Have a good day.

PS Here is some info on something similiar:

If you want a software version of what you are looking for check Software602's <a href="http://www.software602.com/products/ls/" target="_blank">LanSuite</a>. It has all the features you are looking for and is free for up to 5 users for both comercial and non-comercial use. You can setup times to automaticly download mail and when users are allowed to connect to the internet via a schedule. I've used it before and it is really easy to use.

If you have your heart set on an external device such as a router I would suggest the Dlink <a href="http://www.dlink.com/products/broadband/di704/" target="_blank">704</a> or the <a href="http://www.dlink.com/products/broadband/di704p/" target="_blank">704p</a> which has a print server as well. All's you need is an external modem and your in business.

I like Cisco (and own their stock) so, take a look at the 1700 series router. If you buy a modular router you can always upgrade it later from dialup access to T1 or fractional T1 (or dsl if they have the modules available.) Upgradability makes your dollar go farther.

It's amazing how many areas in such a high density state such as NJ can't get DSL. I've used 3Com's 56K Office Connect 56K LAN Modem for quite a few such customers. I've even stuck 3Com's in places when other customers have had their DSL go out (just a day or so? Nah, their DSL was out for WEEKS!). Easy to set up, no maintenance issues, long lasting, and CDW has them for $205 but one could certainly beat their prices with s little research. Even on eBay.
