Voice over Secure IP

You can configure phones to dynamically use either Secure Real Time Protocol (SRTP) or Real Time Protocol (RTP) depending on the media security mechanisms negotiated between phone and outbound proxy using Voice over Secure IP (VoSIP). When you enable this feature, the voice signals are transferred securely between endpoints without the need to introduce multiple lines in the Session Description Protocol (SDP).

The following are advantages for Voice over Secure IP (VoSIP):
  • The voice signals are encrypted and secure allowing a safe transmission of signals between phones.
  • Signaling and media to the cloud hosted product are encrypted.
