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 tablet behind a firewall or NAT.

• 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.

Encrypt Audio

You can encrypt a phone call at the media (audio) level:

• Never: Audio is not encrypted.

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.

calls.

Single Register
