BYOC Trunk Registration Failing with 403 Forbidden During Schedule Publish

Stumbled on a weird bug today with BYOC trunk registration timing out during our weekly schedule publish in Genesys Cloud.

  • Environment: Chicago-based BPO, BYOC trunks via Twilio.
  • Error: 403 Forbidden when attempting to update the trunk base settings.
  • Timing: Occurs exactly when publishing schedules for 200+ agents.
  • Impact: Agents lose inbound routing capability for 15 minutes.
  • Context: Verified trunk credentials are valid and not expired.

check your api throughput during the schedule publish. pushing 200+ agents can hit rate limits, causing the edge to reject the sip registration with a 403. try staggering the publish or adding a delay in your jmeter script to keep request rates under the platform api limits.
