4.2 Programming the Virtual 16-Channel VoIPGateway CardThere are 2 methods to programme the V-IPGW16 card (Virtual 16-Channel VoIP Gateway Card) to establishVoIP communications between PBXs at different locations, as follows:PBX code method The caller dials the unique PBX code of the PBX to which the called party isconnected, in addition to the destination number.Extension numbermethodThe caller dials only the destination number of the called party to call throughPBXs at different locations (hence there are fewer digits to dial than with thePBX code method).NoteFor a detailed explanation about each method, refer to "1.30 Networking Features" in the Feature Guide.4.2.1 Assigning the Hunt PatternThe hunt pattern determines how to route incoming calls through virtual IP trunks to the PBX.
