Maximum time

This is the maximum wait time between attempts to reregister. Once this maximum is reached,
Bria will wait this time for all subsequent attempts.
For example, the min. time is 20 secs, the maximum time is 120 secs. Bria will attempt to
reregister as follows:
• Wait 20 secs.
• Attempt to connect.
• If fail, wait 40 secs.
• Attempt to connect.
• If fail, wait 80 secs.
• Attempt to connect.
• If fail, wait 120 secs (the maximum)
• Attempt to connect.
• If fail, wait 120 secs, and so on.

The factory setting is 1800.

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.

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 68) is ignored.
Typically off. This field is intended for test labs and may cause problems in a NAT environment.
