Cisco TelePresence is a virtual meeting solution developed by Cisco Systems. It provides a high-definition setup designed to link two physically separated rooms audiovisually. It provides a means of communication that appears to emanate from the person speaking, with multichannel, discrete, full-duplex audio with echo cancellation.
The digital signal processors (DSPs) in Cisco TelePresence encode the digital video signal from cameras at 30 frames per second into Real-Time Transport Protocol (RTP) packets using the H.264 encoding and compression standard. The codecs support Secure Real-Time Transport Protocol (SRTP) and Datagram Transport Layer Security (DTLS) methods for securing media traffic.
A typical TelePresence call consists of two media streams, video and audio, that communicate via the RTP. Certain Intrusion Prevention System (IPS) devices could detect a TelePresence call as malicious traffic and could create an alert for administrators. This behavior could occur because the traffic is encrypted and compressed.
