Global IP Mobile This setting has the same function as Global IP Wi-Fi, but applies only when you are connected
over mobile network.
If you set this setting to On, you must also set Global IP Wi-Fi to On.
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. You may need to install a certificate on your Android
phone; speak to your VoIP service provider.
Encrypt Audio 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.
Incoming Calls Typically On (which means you can receive calls on Bria). If Off, you will not be able to receive
calls.
Single Register Applies only if Global IP is on.
• On (checked): Bria will register using a single register request.
• OFF: Bria will register using an unregister and a register.
Only turn on if advised by your VoIP service provider.
Connection Reuse When On the app uses existing connections by including an 'ob' parameter in a header as defined
in RFC5626. Changing this setting might solve problems with dropping or holding calls. The
default is On.
Refresh Interval The timer interval between Bria’s attempts to register in order to refresh the account registration.
Range 30-900 in seconds. 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.
Refresh Mobile Interval This setting has the same functionality as Refresh Interval, but applies only when you are
connected over the mobile network.
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.
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://
Keep Alive - Wi-Fi Interval A “keep alive” message is a mechanism for maintaining a “pinhole” through your firewall so that
phone calls proceed smoothly. The interval specifies how often the message is sent (in seconds).
If you are experiencing problems during a Wi-Fi call (a call made over the Wi-Fi internet
connection), try setting this interval to a lower number such as 20.
Keep Alive - Mobile Interval Same as above, except the interval applies to calls made over the mobile network.
