WebRTC Softphone 409 Conflict During Zero-Diff Terraform Apply

Just noticed that the WebRTC softphone configuration drifts immediately after a clean Terraform apply. The HCL matches the API response, yet the next refresh shows a hash mismatch on the media_region attribute.

Context:

  • Terraform v1.6.4
  • Genesys Cloud Provider v1.12.0
  • Environment: EU-WEST-1

Question:
Is this a known provider bug or a caching issue? Looking for a workaround to suppress this false positive drift.
