# cm_fpg.agi version 2.14
# 
# Designed to work with Cell Menus to allow the entry of a CID number into a 
# Filter Phone Group. It is designed to work easily in the Call Menu framework, 
# it plays no audio itself, and it has more options.
#
# Flag Options:
# 1- Filter Phone Group ID to insert into
# 2- call menu option to send the call to after executing (Default=B)
# 3- (optional) number to enter instead of CIDnumber
#
# example of what to put in the AGI entry for a Call Menu AGI route(CID method):
# cm_fpg.agi,TEST_FPG---B
#
# example of what to put in the Custom Dialplan Entry of a Call Menu (caller entry of number method):
# exten => _XXXXXXXXXX,1,cm_fpg.agi,99test---C---${EXTEN}
