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 iPad; 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.
Incoming Calls Typically ON, in order to receive calls. If OFF, you will not be able to receive calls using Bria.
Single Register Applies only if Global IP is ON.
• ON: Bria will register using a single register request.
• OFF (default): Bria will register using an unregister and a register.
Only choose ON if advised by your VoIP service provider.
Refresh Interval The timer interval between Bria’s attempts to register in order to refresh the account registration.
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.
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 - Cell Interval Same as above, except the interval applies to registrations made over the cellular network.
Presence Agent Turn ON only if your VoIP service provider supports this service for SIP SIMPLE.
