Abstract
A method and system for providing remote voice communication service via a wireless local area network (WLAN). A WLAN access point is arranged with predefined security settings to establish a VPN tunnel over a packet network with a VPN terminator on a remote network. The access point then wirelessly receives voice traffic from a wireless terminal operating in the WLAN and sends the voice traffic over the VPN tunnel to the remote network, for transmission to a call control device, which provides connectivity with a voice transport network. And the access point similarly receives voice traffic via the VPN tunnel from the remote network and sends the voice traffic wirelessly to the wireless terminal. Advantageously, multiple wireless terminals operating on the WLAN can engage in voice calls concurrently via the access point.
