# call_inbound.agi      version 2.6
# 
# runs at the beginning and ending of every inbound call received
# 
# You need to put lines similar to those below in your extensions.conf file:
# 
# parameters for call_inbound.agi (7 fields separated by five dashes "-----"):
# 1. the extension of the phone to ring as defined in the asterisk.phones table
# 2. the phone number that was called, for the live_inbound/_log entry
# 3. a text description of the number that was called in
# 4-7. optional fields, they are also passed as fields in the GUI to web browser
#
# ;inbound calls:
#exten => _*NXXNXXXXXX*3429,3,AGI(call_inbound.agi,spa2000-----8005553429-----Inbound 800-----x-----y-----z-----w)
