Zones DefaultZone SIP Record Route Address Type: <IP/Hostname>

Example: xConfiguration Zones DefaultZone SIP Record Route Address Type: IP
Zones DefaultZone SIP TLS Verify Mode: <On/Off>
Controls whether the hostname contained within the certificate presented by the external system is verified by the
