WebRTC Softphone STUN Timeout on BYOC Trunk Failover

Struggling to figure out why the WebRTC softphone drops immediately during carrier failover.

  • Using Genesys WebRTC SDK v2.4.1 with BYOC trunks in APAC.
  • STUN binding requests fail with 408 Request Timeout when switching from primary to secondary trunk.
  • No issue on native numbers, only on BYOC legs.
