Not quite.

The 'base' for relative paths would be the 'cwd' (current working 
directory) of the Asterisk process.

You can show the cwd for your running Asterisk by:

 	sudo ls -l /proc/$(pidof asterisk)/cwd

which is a link to the process's cwd.

I suspect if you search your file system ('sudo find / -name 
wireless-executed'), you will find 'wireless-executed' -- probably in the 
directory shown by the above command.

You can set this in the script that starts Asterisk. I set mine to /tmp/ 
('cd /tmp/') so I know where any random file access will occur, relatively 

Thanks in advance,
