Trunk Monitoring - When enabled the Origination Customer Trunk Group will send SIP Option messages to all enabled trunks in the Trunk Group every 60 seconds. If a response to the SIP Option message is not provided or a SIP XXX or XXX response is provided, then the Trunk is marked Inactive. An Inactive Trunk will never be used for new calls. Once XXX consecutive SIP Option responses are returned the Trunk will be marked as Active. This applies to IP / FQDN and SIP Registration based Trunk members.
Time of Day Limit of Day -- When enabled, the Time of Day tab will be displayed in the Menu between Route Advance Logic and Triggers. This tab is used to determine what times during the week that this Trunk Group is available. Use this feature with caution on an Origination Customer Trunk Group as the feature effectively prevents calls to any number in the Trunk Group's associated Routing Plan during the hours outside of the configured Time of Day.
Preserve Caller ID - This setting will pass any configured Caller ID in the SIP message’s From header. If this setting is not enabled, no Caller ID will be sent.

Microsoft Enabled -
Ignore Privacy Header - XXX Houston we have a problem
Early Media - This setting will add an SDP to the provisional response (i.e. SIP 18x) if one was not present. This setting is rarely used on an Origination Trunk Group as most PSTN vendors provide Early Media in their provisional responses.
Bursting Threshold - When enabled, the Bursting Port value can be configured. This value is used to define the ports (sessions) that are available in the Trunk Group beyond the number of sessions the customer is typically paying for. For example, if the customer is paying for 100 ports but wants the ability to burst to 150 ports then the Bursting Threshold should be set to 100 and the Ports field should be set to 150. The Bursting Report XXX identified all bursting calls.
