IP Trunk – (SIP) Session Initiation Protocol
Description
The Electra Elite IPK II Voice over IP Trunk Card SIP package sends real-time voice over the corporate
LAN or WAN. The voice from the telephone is digitized and then put into frames to be sent over a
network using Internet protocol.
Using VoIP equipment at a gateway (a network point that acts as an entrance to another network), the
packetized voice transmissions from users in the company are received and routed to other parts of the
company intranet (local area or wide area network) or they can be sent over the Internet using CO lines
to another gateway.
The IAD(8)-U10 ETU – SIP is an optional interface that can provide IP trunks and Tie Lines. It can
operate in the following modes:
COI
