Abstract
A system and method are described for providing least-cost call routing for mobile wireless devices having access to voice-over-IP (VoIP) infrastructure, such as may be operated by an enterprise having global presence. Using a local wireless connection, such as a wireless local area network (WLAN), a software agent on the mobile wireless device registers with a common, enterprise-wide registrar, which, in turn, informs a VoIP gateway in the device's home region of the device's new location. The home region VoIP gateway will then re-route incoming calls for the device to a VoIP gateway serving the region in which the device is currently located. The local VoIP gateway will then route the call to the device via the WLAN. Seamless routing occurs even when the wireless device obtains a local phone number in a foreign network. Outgoing calls from the device can be routed via the VoIP infrastructure or the foreign network based on availability of service and/or cost.
