Gateway
A device that connects to the network and converts a signal to be transmitted via IP. In telephony the classic use of a gateway is to convert POTS or analog lines to IP. As an example, we use a gateway to bring SIP Trunks into an xBlue Key System.
IP (Internet Protocol)
A protocol that specifies the way data is broken into packets and the way those packets are addressed for transmission. Unlike traditional telephone lines which create a straight path from caller to recipient; IP uses the best available path at any given moment to move data packets between point A & point B. The beauty of IP is that the sending end and receiving end communicate success in sending and receiving to insure all data packets are delivered. A really great concept of IP is that of self healing. If a route is broken and the data packets cannot be delivered an alternate route is automatically selected.
ISDN (Integrated Services Digital Network)
In the telephony world, ISDN was a set of standards introduced for digital lines (trunks). ISDN comes in two flavors, PRI (Primary Rate Interface) which is transported over a T1 (group of 24 digital trunks) where the channels 1-23 are utilized for voice, and the 24th channel is utilized for call control between the PBX and the Telephone Company (23B+D). The second is BRI (Basic Rate Interface) which is transported over a single pair of wires and give 2 voice channels and the 3rd channel utilized for call control (2B+D). PRIs a commonly used in the US and countries that follow the US while BRIs are commonly used outside the US as a substitute for POTS Lines.
Server
The central processor in a network. In our case the server supports the telephony functions in a VoIP network. It manages the connections between the phone lines and the telephones, voicemail, etc.
SIP (Session Initiation Protocol)
Internationally recognized IP telephony signaling protocol used for VoIP. This is the most widely used protocol in the market and is a standard meaning anybody who builds a SIP 2.0 compliant product should work with any other SIP 2.0 compliant device. For instance our Talkswitch is compliant so any off the shelf SIP phone will work as an endpoint for a home phone or a remote worker. The trick with SIP 2.0 is that the combined devices will work to the feature set of the lowest common denominator meaning a SIP 2.0 telephone only support 80% of the SIP feature set then even though the telephone system supports a higher set of features, you will only have the base features of the phone.

VoIP (Voice over Internet Protocol)
This is simply the carrying of voice via IP meaning a standard voice stream is broken into packets at the transmit end, sent over a standard data network (such as the Internet) and reassembled into a voice stream at the receiving end. VoIP traffic is trickier than normal data traffic because the timing of packets on the receiving end is critical. For more detail see Basics of the Internet.
