# agi-VDADfixCXFER.agi      version 2.6
# 
# runs when a Consultative transfer is released by the vicidial fronter as the
# call arrives on another channel so that the vicidial_live_agents record is
# updated to be accurate.
#
# You need to put lines similar to those below in your extensions.conf file:
# 
# ;VICIDIAL Consultative Xfer fix script:
# exten => _8600XXX*.,1,AGI(agi-VDADfixCXFER.agi)
# exten => _010*010*010*015*8600XXX*.,1,AGI(agi-VDADfixCXFER.agi)

# CHANGELOG:
# 60809-1749 - First build
# 60817-1122 - Added output options check from database
# 70212-1252 - Fixed issue with Local/ channel transfers on same server
# 130108-1812 - Changes for Asterisk 1.8 compatibility
