When SRTP is enabled on both IP phones, RTP streams will be encrypted, and a lock icon appears on the LCD
screen of each IP phone after successful negotiation.
If you enable SRTP, then you should also enable TLS. This ensures the security of SRTP encryption. For
more information on TLS, refer "TLS".
