I do not not know how to find the file it is writing to.
You do get into the linux console and the asterisk CLI don't you? I am not so good at it with only about a month of experience.
find / -name "filename" in linux command line interface will find all files on the drive named filename
I have not had to use the asterisk CLI (command line interface) interface very much. But I really want to learn more about the godzillion commands and tweaks there are in linux.
I found it essential to learn some linux and asterisk commands to be able to work a system
The GUI does not do it all. Hope I am not being to dumb for you I am a newbie
