====== Manage callerid number ======

<note important> Transport callerid number requires relay support. </note>

When we need to set different callerid number for different applications, the order in which the system uses the calling numbers is as follows:

  - Truck callerid number (Mandatory)
  - Agent callerid number (Login status)
  - Campaign callerid number (Login status)
  - Device callerid number
  - Truck callerid number

===== Telephone system =====

  * Mandatory use of a unified calling number.

callerid number can be forced on a specify trunk in the system, and all outbound through this trunk ignore any other settings and use this callerid number.
