NOTES: Optional - Connectivity in failover conditions may be possible using TLS over TCP port 443. This will only be done through mutual agreement after consultation with the BT Sales Engineer as TLS over TCP is expected to deliver a degraded service and is not recommended for media. You must consult your BT Sales Engineer prior to using these settings. |
