Host Name 
Configure the IP address or URL for the VoIP provider’s server of the 
trunk. 
Keep Trunk CID 
If enabled, the trunk CID will not be overridden by extension's CID when 
the extension has CID configured. The default setting is "No". 
Disable This Trunk 
If selected, the trunk will be disabled. 
Caller ID 
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. 
When making outgoing calls, the following rules are used to determine 
which CallerID will be used if they exist: 
  The CallerID configured for the extension will be looked up first. 
  If no CallerID configured for the extension, the CallerID configured for 
the trunk will be used. 
  If the above two are missing, the "Global Outbound CID" defined in 
Web GUI->PBX->Internal Options->General will be used. 
CallerID Name 
Configure the name of the caller to be displayed when the extension has 
no CallerID Name configured.
