User Speed Dial

Two-digit codes (71-94) can be programmed to dial external telephone numbers.

User Speed Dial numbers are programmed for each telephone, and can be used only

at the telephone on which they are programmed.

Voice Call

A feature you can use to make an announcement or begin a conversation through

the speaker of another telephone in the system. The telephone you call will not ring.

Instead, the person you call will hear a beep and then your voice. Their telephone

will beep periodically to remind them that their microphone is open.

Voice Call deny

A feature that prevents your telephone from receiving Voice Calls.

Voice message center

If you have subscribed to Call Display services you can receive visual Voice

Message Waiting Indication, providing your telephone has a display. If you have

Voice Message Waiting Indication, you can program the telephone numbers

required to access up to five different Voice Message Centers. You can also

program which of the five Centers is to be accessed by each specific line.

Voice over IP (VoIP)

Voice over IP (VoIP) is the capability to deliver voice using the Internet Protocol.

VoIP is a set of facilities for managing the delivery of voice information using the

IP. In general, this means sending voice information in digital form in discrete

packets rather than in the traditional circuit-committed protocols of the public

switched telephone network (PSTN). A major advantage of VoIP and Internet

telephony is that it avoids the tolls charged by ordinary telephone service.

In addition to IP, VoIPuses the real-time protocol (RTP)to help ensure that packets

get delivered in a timely way. Using public networks, it is difficult to guarantee

Quality of Service (QoS).

Using VoIP, an enterprise positions a VoIP device at a gateway. The gateway

receives packetized voice transmissions from users within the company and then

routes them to other parts of its intranet (local area or wide area network) or, using

a T-1 or E-1 interface, sends them over the public switched telephone network.
