The `webRTCSession` object describes the WebRTC (Web Real-Time Communication) session for one NICE CXOne Interaction handled by the MAX WebRTC softphone. It covers the signalling endpoint, event timers, inbound and outbound media metrics, media endpoint, and per-stage failure flags. For the Amazon Connect equivalent, see [WebRTC session](/docs/webrtc-session). ## Schema ```json theme={null} "webRTCSession": { "signallingEndpoint": { "fqdn": "wss://sydacwrtc01.niceincontact.com" }, "eventTimer": { "initializationTimeMillis": 49, "preTalkingTimeMillis": 324, "handshakingTimeMillis": 268, "signallingConnectTimeMillis": 2, "gumTimeMillis": 36, "cleanupTimeMillis": 5, "iceCollectionTimeMillis": 103 }, "metrics": { "mos": { "min": 4.39, "max": 4.43, "avg": 4.41 }, "rtt": { "max": 121, "avg": 74 }, "jitter": { "max": 6, "avg": 2 }, "inbound": { "packetsReceived": 2336, "packetsLost": 0, "packetsLostPercentage": 0, "bytesReceived": 169788, "audioLevel": { "max": 10, "avg": 3.71 }, "jitterBufferMils": { "min": 0, "max": 1, "avg": 0.31 } }, "outbound": { "packetsSent": 2470, "packetsLost": 0, "packetsLostPercentage": 0, "bytesSent": 202087, "audioLevel": { "max": 2449, "avg": 392.79 }, "jitterBufferMils": { "min": 0, "max": 5, "avg": 1.76 } } }, "mediaEndpoint": { "fqdn": "", "destinationPort": "3478", "sourcePort": "63921", "transport": "", "privateIp": "10.4.3.213" }, "eventFailure": { "iceCollectionFailure": false, "setLocalDescriptionFailure": false, "signallingConnectionFailure": false, "gumTimeoutFailure": false, "createOfferFailure": false, "noRemoteIceCandidateFailure": false, "setRemoteDescriptionFailure": false, "gumOtherFailure": false, "userBusyFailure": false, "handshakingFailure": false, "invalidRemoteSDPFailure": false } } ``` ## Fields | Name | Type | Required | Description | Example | | ---------------------------------------- | ------------- | -------- | ------------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------- | | `signallingEndpoint.fqdn` | string | yes | NICE CXOne WebRTC signalling endpoint FQDN. | `wss://sydacwrtc01.niceincontact.com` | | `eventTimer.initializationTimeMillis` | integer | yes | WebRTC initialization duration in milliseconds. | `49` | | `eventTimer.preTalkingTimeMillis` | integer | yes | Time from session start to first audio in milliseconds. | `324` | | `eventTimer.handshakingTimeMillis` | integer | yes | DTLS handshake duration in milliseconds. | `268` | | `eventTimer.signallingConnectTimeMillis` | integer | yes | Signalling connection duration in milliseconds. | `2` | | `eventTimer.gumTimeMillis` | integer | yes | `getUserMedia` call duration in milliseconds. | `36` | | `eventTimer.cleanupTimeMillis` | integer | yes | Session teardown duration in milliseconds. | `5` | | `eventTimer.iceCollectionTimeMillis` | integer | yes | ICE candidate collection duration in milliseconds. | `103` | | `metrics.mos` | object | yes | Estimated Mean Opinion Score — `min`, `max`, `avg`.
