We would like to implement VoIP to reduce phone calls. How do I configure the router.
In India you cannot connect a data link along with a Voice link. So at your India end you will need a seperate router. If you have a very limited need than you can use VoIP with FXS ports on the router itself. On both sides you need to create dial-peers and assign a dialing scheme. An indicative configuration is here for your reference. Use it judiciously because it is not tested on a live set up.
