Verify TLS Cert Applies only if you use TLS as the transport.
• ON (default): Bria attempts to verify the certificate, sent by the SIP server, to see if it
is trusted. For the certificate to be trusted, a corresponding CA certificate, provided by
your VoIP provider, must be installed on your device (using the iPhone Configuration
Utility for example).
• OFF: Bria accepts the certificate without attempting to verify it.
Support RPort • On: the outgoing INVITE message will have an RPort parameter inside the Via
header, which indicates that Bria supports RFC 3581. If the server also support RFC
3581, the server should respond with the RPort parameter set to the incoming public
IP port and the received parameter set to the public IP address. This is the default
behavior in previous Bria versions.
• Off: Bria does not have the RPort parameter in the Via header.
If your calls drop within 30 seconds to 2 minutes after the call is successfully established,
try different combinations of RPort and PRACK: off/on, on/on, on/off).
If none of these combinations solve the problem, turn both the settings off again
(default).
Support PRACK • On: Bria advertises that it supports “100rel” and allows PRACK, as defined in RFC
3262. The outgoing INVITE message will have “100rel” in the Supported header and
“PRACK” in the Allow header. This is the default behavior in previous Bria versions.
• Off: Bria will not advertise these features; there will be no “100rel” in the Supported
header.
If your calls drop within 30 seconds to 2 minutes after the call is successfully established,
try different combinations of RPort and PRACK: off/on, on/on, on/off).
If none of these combinations solve the problem, turn both the settings off again
(default).
Verbose Logging Leave this setting OFF unless customer support instructs you to turn it ON in order to
troubleshoot a problem you are having on your device. See page 47.
