Use ICE Wi-Fi ICE is involved only in media routing (it is not involved in SIP signaling).

ON: Bria will use ICE to discover addresses for media packets. ICE provides a good guarantee of

two-way audio. However, to use ICE successfully, both endpoints in a call must use ICE and

specifically must use draft 19 of the ICE standard.

OFF: Try turning ICE off if you are not using Android phone behind a firewall or NAT.

Use ICE Mobile This setting has the same function as ICE Wi-Fi, but applies only when you are connected over

the mobile network.

Global IP Wi-Fi • On (checked): 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 IPs at the signaling level. Typically, you turn this field off

only if instructed to do so by your VoIP service provider or system administrator.

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.

• Optionally: 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.

• Best Effort: Similar to "Optionally", but Best Effort has more chances of establishing calls. If

you have trouble establishing a call using "Optionally", try Best Effort. With Best Effort, first

Bria requests audio encryption when making a call. If the remote party cannot accept the

encrypted call, then Bria immediately makes a non-encrypted call to the person.

Incoming Calls Typically On (which means you can receive calls on Bria). If Off, you will not be able to receive

calls.

Wi-Fi 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

Change this value only if advised to do so by your VoIP service provider.

Mobile Refresh Interval This setting has the same functionality as Refresh Interval, 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://

Single Register • 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 • 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.
