Voice Over Internet Protocol (Voip) - NEC Electra Elite IPK II Features And Specifications Manual

Electra Elite IPK II
Description
VoIP (Voice over Internet Protocol) allows the delivery of voice information using the Internet protocol
(sending data over the Internet using an IP address). This means that voice information, in a digital form,
can be sent in packets over the Internet rather than using the traditional public switch telephone network
(CO lines). A major advantage of VoIP and Internet telephony is that it avoids the tolls charged by
ordinary telephone service.
Using VoIP equipment at a gateway (a network point that acts as an entrance to another network), the
packetized voice transmissions from users within the company are received and routed to other parts of
the company's intranet (local area or wide area network) or they can be sent over the Internet using CO
lines to another gateway.
The VoIP supports the following:
Trunks: IP CCIS, H.323 and SIP Trunks Compressions of G.711, G.723 and G.729
J
Stations: Megaco Compressions of G.711 and G.729

Using LANs
Using a LAN setup (local area network) with the Electra Elite IPK II system complies with the ethernet
standard (10Base-T/100Base-TX).
3. The voice quality of VoIP is dependent on variables such as available bandwidth, network latency and Quality of Ser-
vice (QoS) initiatives, all of which are controlled by the network and internet service providers. Because these vari-
ables are not in NEC's control, it cannot guarantee the performance of the user's IP-based remote voice solution.
Therefore, NEC recommends connecting VoIP equipment through a local area network using a Private IP address.
