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.
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.

Secs The timer interval between Bria's attempts to register in order to refresh the account
registration.
