I have a large number of teleworkers that currently are using local phone numbers into their home offices. These lines have the distinctive ring feature for faxes and use analog phones. The users want to keep their local lines, distinctive ring and faxes yet go to IP Telephony using the 7941G phone connected to the main corporate system. I've been looking at the 2800 series router as it can do VPN and voice gateway services. For distinctive ring I have to add a third party device. The problem is, this is expensive times hundreds of people. As a second thought, I was thinking of a VPN router and a separate voice gateway from Multitech.
I'd appreciate and ideas, comments, warnings or experiences with this type of problem.
