Administering a Sametime SIP Proxy/Registrar

This section describes how to manage the properties of a Sametime® SIP Proxy/Registrar.

About this task

Session Initiation Protocol (SIP) is a protocol that manages communication in IBM® Sametime meeting rooms by maintaining a dialog with each participant, and ensuring that all media flows between meeting participants. SIP makes use of elements called proxy servers to help route information to the user's current location, authenticate and authorize users for meetings, and provide features to users. SIP also provides a registration function that allows users to send their current locations for use by proxy servers.
