# agi-CANADA_PRI_CIDname.agi version 0.1 
# 
# Runs after call goes through IAX loop to send out custom CallerIDname on
# Canadian PRIs that allow dynamic setting of CIDname with call initiation
#
# You need to have lines similar to those below in your extensions.conf file:
#
# ;outbound VICIDIAL calls:
#exten => _91NXXNXXXXXX,1,AGI(call_log.agi,${EXTEN})
#exten => _91NXXNXXXXXX,2,AGI(agi-CANADA_PRI_CIDname.agi,${EXTEN})
#exten => _91NXXNXXXXXX,3,Dial(${TRUNKX}/${EXTEN:1},55,tTo)
#exten => _91NXXNXXXXXX,4,Hangup
