• Support for SIP URI and DN based interception
• Support for intercepting RTP media types such as audio, video, image (fax), clearmode
• Support for intercepting any SIP signaling messages

• Support for sending intercepted signaling messages over TCP, using an optional IPSec tunnel

• Support for Real Time Control Protocol (RTCP) interception
• Support for Video and auxiliary video interception
• Support for Message Session Relay Protocol (MSRP) and Binary Floor Control Protocol (BFCP) interception
• Support for Far End Camera Control (FECC) interception
