The FQDN in Contact Header should be the same FQDN used in Office 365 Tenant Online Gateway. If the IP Address of the SBC is configured in the Contact Header instead of the FQDN of the SBC, a Forbidden message is received.NOTE: If you set this field to Static and you expect the port number of the Contact header in the outbound SIP messages, you must configure the Static Host FQDN/IP field with the Listen Port number of the SIP signaling group.
