Caller ID (CID)
The "called from" name and number that is transmitted and displayed over telephone lines. The caller has the ability to block delivery of this information by dialing 67 before dialing the destination number.
DECT (Digital Enhanced Cordless Telecommunications)
A digital wireless telephone technology that is expected to make cordless phones much more common in both businesses and homes in the future. Formerly called the Digital European Cordless Telecommunications standard because it was developed by European companies, DECT's present name reflects its global acceptance. Like another important wireless standard, Global System for Mobile communication (GSM), DECT uses time division multiple access (TDMA) to transmit radio signals to phones. Whereas GSM is optimized for mobile travel over large areas, DECT is designed especially for a smaller area with a large number of users, such as in cities and corporate complexes. A user can have a telephone equipped for both GSM and DECT (this is known as a dual-mode phone) and they can operate seamlessly.
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.
Hold
A business feature where a call is temporarily held by the KSU or Server and the caller typically hears music or an announcement during this time. Hold is used while sending the caller to another extension, while setting up a conference call, or while answering another call or simply when looking up information.
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.
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.
Speakerphone
A phone that has a microphone and a speaker that allows you to talk to your caller without lifting the handset. This is best used in private offices and when multi party conferencing is required. Never use a speakerphone in a noisy environment.
Transfer
This business feature allows an employee to send a call to another phone without having to announce the call first. This is the typical means for moving a call through a PBX phone system.
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.
