IP PBX Setup
SIP Basic Setting
SIP (Session Initiation Protocol) is a request-response protocol, dealing with requests from clients and
responses from servers. Participants are identified by SIP URLs. Requests can be sent through any
transport protocol. SIP determines the end system to be used for the session, the communication
media and media parameters, and the called party's desire to engage in the communication. Once
these are assured, SIP establishes call parameters at either end of the communication, and handles
call transfer and termination.
