> AsteriskNow64 3.0.0 running under VMWare workstation.
> There are two issues have been found while I am testing our HiTPM with AsteriskNow64 3.0.0 integration.
> Reproduce steps:
>   1) Install netcat
>   2) Create two test files as:
>      echo 0123456789 >/tmp/0123456789.txt
>      base64 -w 0 /var/lib/asterisk/sounds/en/vm-login.ulaw > /tmp/vm-login.ulaw.b64
>   3) Run: ifconfig;nc -l 4573
>   4) Add a peer for SIP client into sip.conf
>   5) Create an extension for an AGI(agi://[the_ip_address_of_nc_listen_on]) 
>   6) Call the AGI extension
>   7) If setup is correct, the nc windows should have AGI headers
>   8) Send following commands by nc:
> {noformat}
>      GET VARIABLE FILE("/tmp/0123456789.txt,2,5")
>      and 
>      GET VARIABLE FILE("/tmp/vm-login.ulaw.b64,4080,5100")
> {noformat}
>   9) Verify the result:
> {noformat}
>      GET VARIABLE FILE("/tmp/0123456789.txt,2,5")
>      200 result=1 (234)
> {noformat}
>      Base on previous version Asterisk and current document, it should
>      return (23456), the first argument is offset and the second argument
>      should be length, but it is the 1 before the end position now. 
> [Edit by Rusty Newton - removed secondary issue as you shouldn't file two bugs in one report. Filing a new issue report.]
