# cm_status_dial.agi   version 2.14
# 
# Used as a Call Menu AGI option route to alter status of a lead before dialing.
# The lead is only updated if the call is tagged with a lead_id before this script.
#
# You need to put lines similar to those below in your extensions.conf file or 
# a Custom Dialplan entry:
# ; Below are the parameters needed for the script to be run properly
# ; 1. the status to change the lead to
# ; 2. the phone number or extension to dial
# ; 3. the context to dial in
# ;
# ;inbound calls check calltime:
