Prepend CID

The cf_prepend_cid module can be used to prepend static values to the Caller ID Name and Number for a call in callflows.

Configuration Values

Key Description Type Default Required
action If the action parameter is "reset" the caller-id-name and caller-id-number will be restored to their original values, if the value is "prepend" then the prepending will happen string "prepend" no
caller_id_name_prefix The prefix that should be applied to the caller-id-name string "" no
caller_id_number_prefix The prefix that should be applied to the caller-in-number string "" no
apply_to Either "original" or "current", this specifies that the prefix's should be applied to the current caller-id's or the oginial values string "original" no


  • After the callflow action is run, the original caller-id values will be stored in the original_cid_name and original_cid_number fields of the call.
  • When using "current" for the apply_to you can get into a situation where it will append the value multiple times if the callflow is included in a loop.
