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 Account tab (page 45) 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.
