Background
We operate out of the Chicago timezone (America/Chicago) and rely heavily on automated shift swaps and schedule publishing via the Workforce Management API. Recently, we noticed that agents participating in active shift trades are experiencing intermittent SIP registration failures when their status changes from ‘Available’ to ‘Busy’ or vice versa during high-volume periods.
Issue
When an agent’s schedule is updated via the WFM self-service portal, the downstream SIP trunk configuration seems to lag. Specifically, we see 408 Request Timeout errors on the SIP REGISTER method from the Genesys Cloud edge to our carrier trunk. This happens roughly 15-30 minutes after a schedule publish or shift swap is approved. The error correlates directly with the time the agent’s availability state is recalculated by the WFM engine.
Troubleshooting
- Verified SIP trunk credentials and IP allow-lists are correct.
- Checked the WFM API logs; schedule updates are returning
200 OK. - Reviewed the Telephony logs in Admin; no trunk-level outages reported.
- SDK: Genesys Cloud Python SDK v15.2.0 used for schedule publishing.
Is there a known latency between WFM schedule changes and the telephony state propagation? We need to ensure agents can answer calls immediately after a shift swap, but the current registration dropouts are causing missed SLAs. Any insights on decoupling these events or forcing a SIP re-registration?
