[asterisk-users] broken pipe in perl agi

[Danny Nicholas]

Here's what I got from agi debug:

Any other ideas?

Sounds like you have violated the AGI protocol.

1) Does "agi debug' provide any insight?

2) When you run it from the command line are you supplying an AGI 
environment like

 	sh agi-environment.sh\
 		| /var/lib/asterisk/agi-bin/hintcheck.agi foo

where agi-environment.sh looks something like:

# the standard AGI environment variables
         echo "agi_accountcode: "
         echo "agi_callerid: 1234567890"
         echo "agi_calleridname: sedwards"
         echo "agi_callingani2: 0"
         echo "agi_callingpres: 0"
         echo "agi_callingtns: 0"
         echo "agi_callington: 0"
         echo "agi_channel: SIP/201-09456478"
         echo "agi_context: newline"
         echo "agi_dnid: *"
         echo "agi_enhanced: 0.0"
         echo "agi_extension: *"
         echo "agi_language: en"
         echo "agi_priority: 1"
         echo "agi_rdnis: unknown"
         echo "agi_request: block-ani"
         echo "agi_type: SIP"
         echo "agi_uniqueid: 1195070681.28"
         echo ""

         echo "200 result=0"
         echo "200 result=0"
         echo "200 result=0"

# (end of agi-environment.sh)
