Global IP Wi-Fi • ON (default): Bria will publish its public IP address at the signaling level. The public address
may not work with some NATs or firewalls.
• OFF: Bria will publish its private IP address at the signaling level.
"Off" represents server-based network traversal, "On" app-based.
Global IP Mobile This setting has the same functionality as Global IP Wi-Fi, but applies only when you are
connected over the mobile network.
Use Tel URI Change this value only if advised to do so by your VoIP service provider.
• ON: Prefix SIP URIs with tel://
• OFF (default): Prefix SIP URIs with sip://
SIP Transport Tap to display the choices. Contact your VoIP service provider to identify the types of transport
that are supported.
• UDP and TCP do not support signal encryption.
• TLS does support signal encryption. If TLS is selected, a given call will be encrypted if the
other person also uses TLS. You may also need to install a certificate on your BlackBerry
device; speak to your VoIP service provider.
Encrypt Audio If the transport is set to TLS, you can encrypt a phone call at the media (audio) level:
• Never: Audio is not encrypted.
• If Possible: On a given call, audio will be encrypted if the other person supports and is also
using audio encryption. If not, audio will not be encrypted.
• Always: Audio will always be encrypted. The call will fail if the other person cannot accept
encrypted calls.
Wi-Fi Refresh Interval The timer interval between Bria’s attempts to register in order to refresh the account registration
over Wi-Fi network. This value is placed in the “Expires
” header field of the SIP REGISTER
message. Change this value only if advised to do so by your VoIP service provider.
Mobile Refresh Interval Same as above, except the interval applies to registration made over the mobile data network.
Keep Alive - Wi-Fi Interval A “keep alive” message is a mechanism for maintaining a “pinhole” through your firewall so that
the account registration is maintained. The interval specifies how often the message is sent (in
seconds).
If you are experiencing problems (for example, accounts become unregistered when using a Wi-
Fi connection), try setting this interval to a lower number such as 20.
Keep Alive - Mobile Interval Same as above, except the interval applies to registrations made over the mobile data network,
which can be made on an BlackBerry device when you are not in a Wi-Fi zone.
Single Register Applies only if Global IP is ON.
• ON (default): Bria will register using a single register request.
• OFF: Bria will register using an unregister and a register.
Passive Session Timer Controls the use of session timers on SIP accounts. The session timer is used to determine if the
call is still active. Only choose Off if advised by your VoIP service provider.
• ON (default): Bria will not use session timers in any session, except it is explicitly required by
the remote party.
• OFF: Bria will use session timers in all sessions whenever the remote party supports and uses
it.
Connection Reuse • ON: Bria uses existing connections by including an “ob“ parameter in a header as defined in
RFC5626.
• OFF: Bria does not reuse existing connections.
Changing this setting might solve problems with dropping or holding calls. The default is On.
Enable IMS When ON, Bria supports the IP Multimedia Subsystem. The default is Off. Subject to VoIP
service provider. Only choose ON if advised by your VoIP service provider.
