Advanced settings (SIP)

Reregister every: The time interval measured in seconds between Bria’s attempts to reregister in order to refresh the account registration with the account’s VoIP service provider. A value of zero means that Bria should not attempt to reregister after the initial registration. This value is placed in the Expires header field of the REGISTER message.

Minimum time: If the reregister fails, Bria waits this amount of time, measure in seconds, and then attempts to reregister. If the second attempt fails, Bria waits twice this time and tries again. Each time the attempt to reregister fails, Bria increases the amount of time between tries until registration succeeds.

Enable session timers: A session timer is a mechanism to detect whether a call session still active from a signaling point of view. When the timer expires, a refresh is sent from one party to the other. This timer is then reset.

Selected: Turns on the session timers.

Cleared: Turns off session timers, refreshes will never be sent.

Session time preference: Specifies how Bria uses session timers.

Inactive: Session timers are not used in any session, except when it is explicitly required in the remote request.

Optional: Session timers are used in all sessions whenever the remote party supports and uses it.

Required: Session timers support is a requirement for the remote party to be able to establish a session.

Always: Sessions timers are used in all sessions whether or not the remote party supports or uses it.

Default session time: The default value of the session timer measured in seconds.

Hold method: Change this setting only if your VoIP service provider advises you to.

Handle hold request in M-line only (latest standard)

Handle hold request in M-line and C-line (old standard)

Send SIP keep-alives: Typically selected. Instructs Bria to send SIP keep-alive messages in order to maintain a “pinhole” through your firewall for SIP messaging.

Use rport: Typically selected.

Use SIP Outbound: Determines Bria uses an existing connection.

Selected: Bria uses an existing connections by populating the SIP header as specific to RFC 5626. The SIP server should communicate with Bria using the same connection if the transport is set to TCP or TLS.

Cleared: Bria does not use an existing connection.

Force outbound proxy on all requests: Typically Cleared. Use this setting only if you have trouble connecting to the SIP server.

Selected: Requests always go to the outbound proxy configured in Send outbound via on the Account (Windows) or General (Mac) panel. Bria never sends the invite directly to the end point. If you select this field, make sure you also set Send outbound via.
