RTP Port Start Change this value only if advised to do so by your VoIP service provider.
This indicates the start of the ports range used for RTP and RTCP sessions. The range is
100 ports wide. The range is not observed if ICE is used. The default is 4000.
Audio Codecs Selection Tap to display more information about these two fields. See page 59.
Video Codecs Selection Appears after the Video Calls premium feature is purchased. See page 60.
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 iPad 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 supports 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.
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.
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 63.
Send Log Tap to upload the current log to customer support. See page 63.
Call Statistics To show detailed information about the current/last call. For example, the number of
packets lost.
