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. The factory setting is 60.
• 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.
Hold method Choose the appropriate value. If necessary, speak to your service provider.
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 Account tab (page 24) is ignored.
If you check this field, make sure you also set “Send outbound via” (on Accounts > Account) to
“Domain”.
Typically off. This field is intended for test labs and may cause problems in a NAT environment.
