35.3.2 Configuring WebRTC

To support WebRTC, you need to perform special configuration settings for the device's
SBC leg interfacing with the WebRTC client (i.e., Web browser). The following procedure
describes the required configuration.

To configure WebRTC:
1. Configure DTLS for communication between the device and the WebRTC client (see
''SRTP using DTLS Protocol'' on page 212)
2. Enable ICE: For the IP Profile associated with the WebRTC clients, configure the 'ICE
Mode' parameter (IPProfile_SBCIceMode) to Lite (1).
3. Enable RTCP Feedback: For the IP Profile associated with the WebRTC clients,
configure the 'RTCP Feedback' parameter (IPProfile_SBCRTCPFeedback) to Enable
(1).
4. Enable RTCP Multiplexing: For the IP Profile associated with the WebRTC clients,
configure the 'RTCP Mux' parameter (IPProfile_SBCRTCPMux) to Supported (1).
5. WebSocket:
a. On the SIP General Parameters page, configure the keep-alive interval with the
WebSocket client, using the 'WebSocket Keep-Alive Period' parameter
(WebSocketProtocolKeepAlivePeriod).
b. Open the SIP Interface table (''Configuring SIP Interfaces'' on page 342) and for
the SIP Interface associated with the WebRTC clients, configure the
'Encapsulating Protocol' parameter (SIPInterface_EncapsulatingProtocol) to
WebSocket (1). The setting identifies WebSocket traffic on the SIP Interface.
