These are evaluation paths, not production-certified telephony releases. Production publication of PBX/native-SIP previews is blocked by the publisher release gate. Automated local evidence does not replace clean-machine installation, physical audio, carrier, or site qualification.
The standard Server installer automatically provides telephony capabilities or connection options for an existing PBX. Administrators review network settings and provision per-Agent accounts from the central administration interface.
Telephony configuration includes extensions, trunks, queues, IVR, and conference rooms. An optional signed-outcome endpoint can reconcile bounded PBX reports to voice interactions after signature, Call-ID, freshness, and duplicate checks; it requires a customer-controlled adapter and public-key trust and does not automatically change interaction disposition. Encryption, certificates, recording/media privacy, firewall, and external-provider limits require separate review. Never treat this preview as Internet-facing qualification.
