Building a WebRTC Communication and collaboration platform - techleash barcamp

WebRTC allows for multimedia communication directly through the browser without plugins. It uses peer-to-peer connections for media and can utilize various signaling protocols to broker connections. WebRTC is supported by all major browsers and can be used for personal communication, telehealth, call centers, IoT, and other use cases. However, concerns remain around firewall traversal, security, integration with other standards, and legal issues regarding privacy and lawful interception.

- 17. Concerns ? 4/19/2015 Altanai Bisht . website:http:// altanaitelecom.wordpress.com17 Firewall / policies blockage NAT issue is major ICE is complicated setup own STUN or TURN server Security SRTP / web breaker / DTLS too much and too ambiguous for a developer No one talking about - SPAM control / Unwanted call screening / risk mitigation RTP stream multiplexing RTP + RTCP Conferencing involves Multiple RTP streams. No standard network topology to work Interworking Simple to call between WebRTC bowers ( full audio and video ) Confusion on integration with OTT solutions (Skype, Viber, Google Jingle , XMPP etc.) SBC ( Media transponders and Proxy servers ) have demonstrated interworking with NGN/IMS More clarity required on integration with legacy PSTN and PLMN . Even GSM / UMTS as they have different number formats ( ENUM can be used ) ISUP and legacy codecs .
- 18. Legal Issues ? 4/19/2015 Altanai Bisht . website:http:// altanaitelecom.wordpress.com18 Who is hosting the comm platform? Identity resolution for authentication? Detecting the service man-in-the-middle attacks Network sniffing ( users location , device and call activity ) Lawful interception required in many Organizations Session Replay Media Interception Tough to track where is signal passing through in IP network? Media Encryption (DTLS) Who has the keys ? Media Server employed to force relays adding to complexity RTP multiplexing is hugely a black box
