# CID_change.agi
# 
# Changes the CID number on calls that pass through it to the cid_group_id 
# defined in the flag below OR a specific CID number in that place.
# If a CID Group is used, script will try to find CIDs within phone number 
# dialed areacode. If none are found, it will grab a random active CID in the
# CID group to use.
#
# Flag Options: (separated by three dashes '---')
# 1- Fixed CID number, or a valid CID Group ID
# 2- number of digits to strip before the phone number
# 3- number of digits in the area-code
# 4- should always be ${EXTEN}
#
# You need to have lines similar to those below in your Custom Dialplan:
#
#; change CID to a CID within the 'testCIDgroup' CID Group:
#exten => _91NXXNXXXXXX,1,AGI(CID_change.agi,testCIDgroup---2---3---${EXTEN})
#exten => _91NXXNXXXXXX,n,Goto(default,${EXTEN},1)
#
#; change CID to a fixed CID:
#exten => _91NXXNXXXXXX,1,AGI(CID_change.agi,9998887112---------${EXTEN})
#exten => _91NXXNXXXXXX,n,Goto(default,${EXTEN},1)
#
# The easiest way to set this up for a phone is to create a new Call Menu and
# then put the above Custom Dialplan into it, then set the Phone's 
# 'phone context' to the call menu ID that you just created.
