"agi debug" (and syslog()) are the AGI developer's best friends :)

It shows the dialog between Asterisk and your AGI. Even if your AGI fails 
to exist or execute, you will still see Asterisk setting up the AGI 
environment for you, just none of the subsequent dialog.

I use the following script to fake the AGI environment:

# 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: 3"
         echo "agi_rdnis: unknown"
         echo "agi_request: block-ani"
         echo "agi_type: SIP"
         echo "agi_uniqueid: 1195070681.28"
         echo ""

# cruft specific to my AGI

# result for AGI command SET PRIORITY
         echo "200 result=0"

# result for AGI command GET VARIABLE ANI
         echo "200 result=1 (1234567890)"

# result for AGI command GET VARIABLE CALLINGANI2
         echo "200 result=1 (0)"

# result for AGI command GET VARIABLE DATABASE-SERVER
         echo "200 result=1 (pdb)"

# result for AGI command SET PRIORITY
         echo "200 result=0"

# (end of agi-environment.sh)

This can be used as:

 	chmod +x agi-environment.sh
 	./agi-environment.sh | block-ani --debug

I use getopt_long() to parse the command line options and syslog() to 
stash stuff to analyze after the fact.

You can even use gdb (if appropriate for your language) by saving the 
output of the script and supplying it in the "r" command as:

 	./agi-environment.sh >agi-environment
 	gdb block-ani
 	(gdb) r --debug <agi-environment

Thanks in advance,
