By default, audio communications between Speech Server and trusted SIP peers is not encrypted and can be vulnerable to eavesdropping. To make media traffic more secure, configure Speech Server to use Secure Real-time Transport Protocol (RTP). When enabled, Speech Server only uses Secure RTP for connections between application instances and trusted SIP peers. You specify to use Secure RTP for each application. For more information, see How to: Configure an Application for Secure RTP Communications.
Note
You cannot use Secure RTP with Telephony Interface Manager Connector (TIMC). For more information, see TIMC Security.
