# cm_cid_change.agi version 2.14
# 
# Designed to allow you to change the CID of a call to either a fixed number or
# a combination of CUSTOMER, CLOSER just like the in-group Action Transfer CID
# feature. Script is designed to handle calls already assigned to leads, not
# new inbound calls that only have a phone number.
#
# Flag Options:
# 1- Fixed CID number, or CUSTOMER or CUSTOMERCLOSER
#
# example of what to put in the AGI entry for a Call Menu AGI route:
# cm_cid_change.agi,CUSTOMERCLOSER
