7.12 Configuring SRTP
This section describes configuring media security. This section describes how to configure media
security. The Zoom Phone System Interface needs to use SRTP only, so you need to configure the
SBC to operate in the same manner. By default, SRTP is disabled.
To configure media security:
1. Open the Media Security page (Setup menu > Signaling & Media tab > Media folder > Media
Security).
2. From the 'Media Security' drop-down list, select Enable to enable SRTP.
3. Click Apply.
