Disable This Trunk Note: If a current SIP trunk is disabled, UCM will send UNREGISTER message
(REGISTER message with expires=0) to the SIP provider.
If the trunk has an assigned PSTN telephone number, this field should be set to
"User=Phone". Then a "User=Phone" parameter will be attached to the Request-
TEL URI Line and TO header in the SIP request to indicate the E.164 number. If set to
"Enable", "Tel:" will be used instead of "SIP:" in the SIP request. The default setting
is disabled.
Configure the Caller ID. This is the number that the trunk will try to use when
making outbound calls. For some providers, it might not be possible to set the
CallerID with this option and this option will be ignored.
Important Note: When making outgoing calls, the following priority order rule will
Caller ID be used to determine which CallerID will be set before sending out the call:
From user (Register Trunk Only)  CID from inbound call (Keep Original CID
Enabled)  Trunk Username/CallerID (Keep Trunk CID Enabled)  DOD 
Extension CallerID Number  Trunk Username/CallerID (Keep Trunk CID
Disabled)  Global Outbound CID.

them.
For Example: User 2002 has dialed external number 061234575 but they were not
Direct Callback reachable, once they have received missed call notification on their phone, they
would mostly call back the number, if the option "Direct Callback" is enabled then
they will be directly bridged to user 2002 regardless of the configured inbound
destination.
