# agi-dtmf.agi - script for playing DTMF tones or signals received as the callerid field or in the command CLI
# 
# DTMF sound files must be in /var/lib/asterisk/sounds for this to work
#
# Accepted values are: 1 2 3 4 5 6 7 8 9 0 # * ,
# comma means pause for 1 second (use 'S' for pause in CLI mode)

# exten => 8500998,3,AGI(agi-dtmf.agi)
#; exten => 8500998,3,AGI(agi-dtmf.agi,signalonly) ; optional signal only DTMF
# exten => 8500998,4,Hangup
#
# Can also be used in a Call Menu: agi-dtmf.agi,signalonly---12345   # optional signal only DTMF with CLI-defined DTMF values
