2 What WebRTC Does NOT Do: “No Numbers” No rendezvous – “no addressing” at all Not like SIPMore islands? Yes, but it is adding high quality real-time communication where we already are in contact.What WebRTC Does:Sets up media directly between browsers (SDP/RTP like SIP) – typically on same web application.“Handles” NAT/FW traversal (ICE, STUN, TURN) – fooling firewalls (like Skype).VoiceVideoData“For free!”

11 Manage the PBX Companion From the PBX GUI The PBX companion, the SBC and the Firewall – all configuration is available via the Websocket connection using the CONFgate protocol.The CONFgate protocolThe client webpage can use a proprietary protocol called CONFgate to communicate with the IXNX unit through a Websocket. The CONFgate protocol allows access to the same command line interface (CLI) as telnet connections.To access the CLI the webpage can open a Websocket connection to IXNX's Websocket server and specify protocol ”CONFgate”. Then supply a valid login and password (same as for the configuration web pages and Telnet).User root is by default not allowed to be logged in. Non-root users are by default logged in to the CLIsh command line interface, not the regular Linux shell. The Websocket server is by default not enabled. CONFgate is by default not enabled. Accessing through CONFgate can be granted/denied individually for different users.Once logged in, the webpage can send CLI commands to read and write configuration using CLI configuration commands like ”uci set sipadv.sip_fent_udp_time=60” and some other commands like ”netstat”, ”ifconfig” and ”fwlog” and receive the command output through the Websocket connection. For a complete list of commands available see CLIsh documentation.As for all user access to the unit, file /etc/config/access/username specifies what parameters a specific user is allowed to read and write, regardless of if she logs in through web interface, telnet, or CONFgate.WS: CONFgateWeb ServerHTTPIf the PBX has web based configuration, you can therein build web pages for the PBX Companion. You simply let the browser code open a Websocket and execute the appropriate configuration CLI commands in the PBX Companion.
12 WebRTC Hooks to the Ingate SIP Proxy E-SBC The WebRTC traffic comes as (i) SIP from the browser (which has got its SIP client code from some webpage) OR (ii) according to the simple Ingate RTCgate protocol (Where the SIP UA, the client, is in the Ingate product). In both cases the transport is via websockets (WS or WSS). All Ingate SIP and SBC features becomes available.The WebRTC client Java Script code may be on any web server (also in the Ingate). The server executing the RTCgate protocol runs on the Ingate.There is more than just SIP, e.g. PBX extensions available through the RTCgate protocol.With Ingate’s Q-TURN (more about that later), important features such as Security, QoS and Accounting (Billing) becomes available also for WebRTC end-to-end (not converting to SIP).
