WebRTC is an exciting new technology that many large enterprises see as a potential cost saving for their remote workers (be there home, mobile or other). However, existing enterprise telephony infrastructures do not use or conform to many of the of advanced standards being presented by the current implementations of WebRTC in the browser. Examining two use cases and the challenges faced. www.thrupoint.com

1. Integrating WebRTC with the traditional

2. WebRTC and the Enterprise
• The enterprise is excited about WebRTC
– Video as a first class citizen on their networks
– Enabling internet calling for home and mobile workers
– Bringing calls “on-net” to save costs
– Reducing IT costs with low maintenance thin clients
– Love for “super thin clients”
• The enterprise is confused about WebRTC
– How does it integrate?
– How much has to change?
– Will it work with my video devices?
• Desk video-phones?
• Mobile clients?
• Tele-presence rooms
– Does it fit into my DMZ?
– Will it work with my SBC?

3. What the Enterprise is saying…..
"WebRTC will reduce our support costs
dramatically”
“WebRTC will enable us to better embrace
business to consumer video”
“WebRTC will enhance out contact center and
customer service operations”
“WebRTC is will improve our internal and external
collaboration”
“WebRTC will improve our customer intimacy”

4. What is WebRTC?
(and why is it a problem to the enterprise)
• Open Standards!
• Clientless, plugin-less browser audio
and video real time communication!
• Open-source codec, VP8!
• ICE/STUN NAT traversal!
• SRTP!
• No rules on signaling protocol!
• Multiplex RTP and RTCP over a single
port!
• Multiplex Audio and Video over a single
port!

6. What is an Enterprise Network?
• Mostly hardware endpoints with hard to
upgrade software.
• Few soft clients generally tied to a PBX
• Limited codec support, H26* for video
only (ok, maybe a bit of RTV)
• ICE, STUN, what‟s that?
• SRTP? That‟s a firewall issue right?
• RTCP shalt be on the RTP port +1 !!!
• Audio shalt be separate to Video !!!

9. Solutions
• Signaling Gateway
– SIP stack in java-script make it a thick client again!
– Convert from something light (ROAP?) to SIP at a
gateway
• De-ice
– Validate SDP ICE candidates
– Pass on the primary candidate as SIP identity
• De-Multiplex
– Take the multiplex stream and split it
– Take the separate streams and recombine
• STUN binding handling
– Respond to STUN bindings on the RTP channels
– Validate bindings
• Transcoding
– Transcode between VP8 to H264

12. Summary
• WebRTC is awesome!
• The Enterprise isn‟t going to be
changing any time soon.
• But they really want in.
• The two can communicate with a little
help.
