**>Subject: Sending an SMS out of Asterisk via Kannel
**>Date: Mon, 18 Jul 2005 13:36:15 -0400
**>
**>GOAL: To pass variables from Asterisk to Kannel when sending out an
**>SMS message using a URL.
**>
**>CURRENTLY: I am able to pass a URL via Asterisk to Kannel and out of
**>my GSM modem BUT I haven't figured out how to include Asterisk
**>variables in the string.
**>
**>I was hoping someone could help me figure out what I'm doing wrong.
**>Perhaps there is a simple AGI I should be using. I am not extremely
**>comfortable writing AGIs but I suppose if I had a great example to
**>modify I could figure it out.
**>
**>Main objective at the moment would be to just modify slightly what I
**>am doing here to pass the variable.
**>
**>WORKING EXAMPLES:
**>This code works when I don't attempt to pass an Asterisk variable, in
**>other words when it's just text in the message:
**>
**>exten => s,9,System(curl "http://127.0.0.1:13370/cgi-bin/sendsms?
**>username=name&password=pass&to=12122122121&from=12122121212&text=Message
**>+text+here")
**>
**>NON WORKING EXAMPLES:
**>When I attempt to pass an Asterisk variable this code does not work:
**>
**>exten => s,9,System(curl "http://127.0.0.1:13370/cgi-bin/sendsms?
**>username=name&password=pass&to=12122122121&from=12122121212&text=Message
**>+text+here+${CALLERIDNUM}")
**>
**>I realize this isn't the most elegant flow. Suggestions are
**>welcome. I was wondering what am I doing wrong in this case though?
**>
**>Thanks for your time and feedback.
Not really a Kannel question ... more of an Asterisk question...
There's nothing wrong with your non-working example except for the
assumption of ${CALLERIDNUM} always returns just digits. It could
return a space character that will screw up the URL.
Check your smsbox logs to verify that Asterisk successfully issued
the HTTP_GET via curl.
Also, add some NoOp() to the dialplan to see the value of
${CALLERIDNUM} that's being passed through to curl. Run asterisk
in debug mode with massive verbose settings (-vvvvvgcn) so you
can see the exact execution path.
This is a working example Macro that prompts for 2 PIN numbers and then
uses Kannel to send an SMS:
[macro-two-pins-in-sms]
exten => s,1,Answer
exten => s,2,Wait(1)
exten => s,3,Read(firstnum|agent-pass|5)
exten => s,4,Read(secondnum|vm-reenterpassword|5)
exten => s,5,NoOp(firstnum=${firstnum}, secondnum=${secondnum},
CALLERIDNUM=${CALLERIDNUM})
exten => s,6,System(/tmp/curl.sh
"http://127.0.0.1:13013/cgi-bin/sendsms?usernamename&password=pass&to=12122122121&from=12122121212&text=Message+${TIMESTAMP}+${firstnum}+${secondnum+${CALLERIDNUM}";);
exten => s,7,Playback(vm-goodbye)
exten => s,8,Hangup
/tmp/curl.sh is a bourne shell script that converts spaces to '+'
for the first argument passed to it:
#!/bin/sh
ARGV1=`echo "$1" | sed -e 's/ /+/g'`
/usr/bin/curl "${ARGV1}"
exit $?
Hope this helps.
See ya...

P.S. For everyone that's been waiting for my modifications to support
retrieval of DLR's using the UUID...I'm still trying to get them
released from Upper Management... (for the past 5 months!!!)
