1. Introducing the LIP-6812 & LIP-6830
1.1 LIP-6812 and LIP-6830 Overview
LIP-6812 and LIP-6830 are Internet Protocol (IP) phones designed to support hosted telephony
services over a managed IP network. Based on the open standard Session Initiation Protocol
(SIP), LIP-6812 & LIP-6830 will interoperate and exchange signaling messages with SIP
Servers, Proxies and gateways while voice packets are exchanged on a point-to-point basis
between the phone and the connected party through the Service Provider’s network.
Features and functions available to the LIP-6812 & LIP-6830 through the SIP Call Server are
similar to those of a conventional business telephone. For ease of use, the LIP-6812 and LIP-

display, Softkeys, and a Dial pad. These elements are described in more detail in section 1.3.
