Most of SIP gateways use UDP for signaling and voice packet transmission as well the AddPac
VoiceFinder Gateway Series.
Generally, SIP proxy server is used accounting and call routing of SIP telephone network.
Some unexpected failure may take a place in internet or power after session is formed between
the terminals (SIP-UA). SIP sever can send re-invite messages periodically to check a call
status SIP-UA and proxy server.
Session timer forms session and sends re-invite from the terminal (SIP-UA) to proxy, proxy to

certain time period, the proxy determines something wrong with the equipment and send BYE
