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.
