# agi-AGENT_dial_in.agi version 0.1
#
# This script is designed to allow agents the ability to dial in to an extension
# to establish the phone connection to their VICIDIAL session. The user login
# and password must be only digits and nothing but digits to use this utility.
#
# user is prompted for their user ID then press #
# user is prompted for their passcode then press #
# then the user is forwarded to the active vicidial agent session
#

#exten => 2345,1,Answer		; Answer the line
