1. Introducing the LIP-6812
1.1. LIP-6812 Overview
LIP-6812 is an Internet Protocol (IP) phone designed to support hosted telephony services over
a managed IP network. Based on the open standard Session Initiation Protocol (SIP), LIP-6812
can interoperate with various third party SIP end-user devices, Proxy/Registrar/Servers, and
gateway products 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 through the SIP Call Server are similar to
those of a conventional business telephone. For ease of use, the LIP-6812 is equipped with
fixed feature buttons, flexible (programmable) feature buttons, an LCD display, Softkeys, and a
dial pad. These elements are described in more detail in the General Description section.
