VoIP technology is now delivering incredible functionality to the telephone handset—no matter where that phone may be located. The ZIP 4x5 packs an incredible amount of technology into what looks like a standard business telephone. The ZIP 4x5 provides all the telephony features that businesses require, and adds networking functionality, Bluetooth wireless, and voice activated dialling. For the remote worker, the ZIP 4x5 connects directly to a DSL or cable modem and provides VPN access, a firewall with NAT, a switch, and a router without additional devices. The ZIP 4x5 is built 100 percent on open standards and is compatible with any IP telephony system using SIP (Session Initiation Protocol).

Previously, a remote worker needed separate products to provide telephony for a remote worker. With the ZIP 4x5, all the functions are incorporated into the phone to simplify connectivity and administration. The remote phone appears as any other device on the company’s PBX. This allows for access anytime, anywhere. Source:Zultys
