Codecs Variable Bitrate This setting applies when the negotiated codec is AMR-WB, SILK, Opus or H.264 (for
video call).
When this setting is turned on, Bria dynamically adjusts the bitrate throughout the call,
based on the current network conditions. For example, when Bria detects many packets
are lost, it tries to lower the bitrate (within the range of a bitrate supported by a specific
codec), in order to ensure the best possible quality under the circumstance.
We recommend that you leave this setting ON, especially when AMR-WB, SILK, Opus
or H.264 is enabled.
If you notice degradation in audio or video quality when your data connection is stable,
you can turn this setting off to see if it makes a difference.
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 60.
Video Codecs Selection Appears after the Video Calls premium feature is purchased. See page 61.
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.
Alert In Background • On: Bria sends notifications when an account fails to register. Bria also notifies the
user after the account is successfully re-registered. Make sure that Bria notifications
are enabled under iOS Settings.
• Off (default): Bria does not send notifications regarding account registration errors.
Enable 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.
Enable 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.
Encode # in URI • On (default): Bria escapes a hash character (#) used in the user part of SIP URI, as
required by RFC 3261.
• Off: Bria does not escape a hash character and sends it as is. Turn this setting off if you
are having trouble making outgoing calls to a number with a hash character.
SDP Port Switching Controls Bria's behaivor to choose the RTP port to send RTP traffic to.
• When ON (default), Bria switches the RTP port when it realizes the remote party is
sending data from a different port.
• When OFF, Bria does not switch the port and keeps using the original one specified in
the SDP body.
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 65.
Send Log Tap to upload the current log to customer support. See page 65.
