Abstract
A method for sending messages between a first PBX device and a second PBX device is provided. The method includes receiving a first message from the first PBX at a first gateway. The message includes a standard section and a proprietary section. The standard and proprietary sections may be provided in a protocol associated with the PBX system. The standard section is decoded but the proprietary section is not. The standard section and proprietary section are then packetized in one or more packets. These packets are then sent over a packet-based network to a second gateway and may be routed over the packet-based network using the decoded standard section. The second gateway is then configured to generate a second message including the standard section and the proprietary section for sending to the second proprietary PBX device.
