The present document describes a method and system for placing a call through an Internet Protocol (IP) network, from a contact voice interface device for use by a contact user located in a first geographical area, to a subscribed voice interface device for use by a subscribed user located in a second geographical area, each geographical area defined by an area in which a local call can be made. The method comprises: assigning a local access phone number to the first geographical area; the contact user initiating a first leg of the call, from the contact voice interface device to a first IP switch, by dialing the local access phone number using the contact voice interface device; the contact user providing an identity of the subscribed voice interface device to which the call is to be completed; transmitting the identity from the first IP switch to a second IP switch via the IP network, the second IP switch associated with the identity of the subscribed voice interface device provided; the second IP switch establishing a second leg of the call at a local calling rate to the subscribed voice interface; and bridging the first leg of the call to the second leg of the call through the IP network, thereby completing the call from the contact voice interface device to the subscribed voice interface device through the IP network.
