# agi-3way_press_agent.agi version 2.14
# 
# Runs when a 3way call using a dial override is placed through a special 
# extension from the agent screen to an outside-agent where that outside-agent 
# will have to press-1 to accept the phone call.
# An example of the special extension: "49907917275551212" where:
#   - 49907 is the special extension
#   - 9 is the dial prefix
#   - 1 is the phone code
#   - 7275551212 is the outside-agent number to be dialed
# 
#	THIS IS THE FIRST REQUIRED AGI SCRIPT OF 2 FOR THIS FEATURE
#
# You need to put lines similar to those below in your extensions.conf file:
#
#; VICIdial agent initation of outside-agent transfer:
#exten => _49907.,1,Answer
#exten => _49907.,n,NoOp(${CALLERID(name)})
#exten => _49907.,n,Playback(sip-silence)
#exten => _49907.,n,AGI(agi-3way_press_agent.agi,start---50---30)
#exten => _49907.,n,Hangup
#
# The CLI flags for the 'agi-3way_press_agent.agi' script above are:
# - stage = 'start' is the only value for this variable
# - 3way agent timeout = number of seconds after launching 3way outside-agent calls before this script times out
# - 3way dial timeout = the Asterisk Dial() timeout for the 3way outside-agent calls
