Rules of SRTP for media encryption in SIP calls:
When SRTP is enabled on both endpoints, RTP streams will be encrypted, and the lock
icon appears on the display device of each endpoint after successful negotiation.
Note
To configure SRTP for SIP account via the web user interface:
1. Click on Account->SIP Account.
2. Select the desired value from the pull-down list of SRTP.
3. Click Confirm to accept the change.
If SRTP is enabled for the SIP account, you should also configure the transport type to TLS.
This ensures the security of SRTP encryption. For more information on TLS, refer to
Transport Layer Security on page 178.
