Bria, enter the domain name or the IP address obtained from your provider.

Auth Name May not be required. But if it is required, it will be provided by your VoIP service provider.

attendant (such as “press 1 for customer service

”).

Enter the value specified by your VoIP service provider.

Global IP • ON: 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 system administrator.

Global IP 3G This setting has the same function as Global IP, but applies only when you are connected over 3G.

If you set this setting to ON, you must also set Global IP to 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://

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 iPhone; 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.
