WebRTC softphone failing to initialize for agents with specific shift constraints

Why does this config cause the WebRTC softphone to fail initialization for agents who are scheduled for early morning shifts in the America/Chicago timezone?

We recently updated our WFM publishing logic to handle complex shift swaps and agent preferences. While the schedule publishes successfully via the /api/v2/wfm/schedule/agent/swap endpoint without 409 conflicts, a subset of agents cannot launch their softphones. This issue is isolated to agents whose schedules were modified within the last 24 hours and who have specific time-off requests pending. The error occurs immediately upon login, before any media is streamed.

The browser console shows a WebSocket connection failed error with status code 403, but the token appears valid. I have verified that the tenant’s WebRTC configuration is enabled and that the agents have the correct webRTC:enable permission. The issue does not persist if I revert the schedule to the previous week’s version, suggesting a data sync lag or a conflict between the WFM state and the user profile’s active status.

Here is the payload we are sending to update the agent’s schedule, which seems to trigger the issue:

{
 "userId": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
 "scheduleId": "sch-987654321",
 "shifts": [
 {
 "startTime": "2023-10-27T06:00:00-05:00",
 "endTime": "2023-10-27T14:00:00-05:00",
 "skillIds": ["skill-voice-support"],
 "isSwap": true,
 "swapReason": "Agent Preference"
 }
 ],
 "timeOffRequests": [
 {
 "startTime": "2023-10-28T08:00:00-05:00",
 "endTime": "2023-10-28T16:00:00-05:00",
 "status": "PENDING",
 "type": "PAID_TIME_OFF"
 }
 ]
}

The agents affected are all using the latest version of the Genesys Cloud desktop application. We are seeing this behavior consistently on Fridays when the weekly schedule is published. Is there a known latency issue with the WFM service propagating active status changes to the WebRTC signaling server? Or could the pending time-off request be inadvertently flagging the user as inactive in the presence service?

Any insights into the interaction between WFM schedule constraints and WebRTC authentication would be appreciated. We need to ensure agents can log in smoothly without manual intervention from the admin team.

I’d suggest checking out at the recording configuration settings rather than the WFM publishing logic. While the schedule swap endpoint returns success, the underlying recording metadata payload for those specific shift blocks might contain null values or invalid timezone offsets that the WebRTC client fails to parse during initialization. This is a known edge case when bulk exporting digital channel data for legal discovery. The client expects consistent metadata structures, and a mismatch in the startTime or endTime fields within the recording context can cause the softphone handshake to abort before the media stream connects. Check the S3 export logs for those specific agent IDs around the failure time. Look for truncated JSON payloads or missing chain of custody headers. A common fix is to force a metadata refresh for the affected agents via the recording API. This ensures the client receives a clean, valid configuration object.

  • recording metadata consistency
  • S3 export job validation
  • WebRTC client initialization logs
  • timezone offset handling in API payloads
