Timers
Enable session timers
Default session time
A session timer is a mechanism to detect whether a call session is still active from the signaling
point of view. When the timer expires, a refresh is sent from one party to the other. The timer is
then reset.
• Turn on to enable session timer. Enter a value in Default session time.
• Turn off to disable session timer; refreshes will never be sent.
Session timer preference This field specifies your preference for which party should send the refresh. The preference is not
a guarantee that the refresh will be performed by the specified party. The choices are:
• None: No preference.
• Local refreshes: Your computer sends.
• Remote refreshes: The other party sends.
• UAC refreshes: The user agent client (the party that initiated establishment of the
communications) sends.
• UAS refreshes: The user agent server (the other party) sends.
Send SIP keep-alives Typically on, to instruct Bria to send SIP keep-alive messages in order to maintain a “pinhole”
through your firewall for SIP messaging.
Use rport Typically on.
Send outgoing request
directly to target When checked, requests with a complete URI ([email protected]) go to ABC.com and the “Send
outbound via” field on the General tab (page 50) is ignored.
If you check this field, make sure you also set “Send outbound via” (on the General tab) to
“Domain”.
Typically off. This field is intended for test labs and may cause problems in a NAT environment.
Use old style hold Check this box only if your VoIP service provider advises you to do so.
