An integrated gateway is disclosed. In one embodiment, a gateway includes a modem, a wide area network (WAN) interface, a local area network (LAN) interface, a router module, a voice-over-internet protocol (VOIP) adapter and a session-initiation protocol (SIP) adapter. The WAN interface is in communication with a packet network, such as a VOIP network. The router module is configured to route data traffic between the WAN interface and the LAN interface. In one embodiment, the VOIP adapter, as does the SIP adapter, includes a wireless interface for wireless communication with an endpoint device. The VOIP adapter is configured to provide VOIP services between the endpoint device and the packet network. The SIP adapter is configured to provide SIP services between the endpoint device and the packet network.
