I have modified the extension_additional.conf file to include a “Callback” feature when stations are busy.
I’m replacing the BUSY script with my own code in the “vm_msg” macro.
HOWEVER, is seems that anytime a phone is added, modified, or deleted, this file is rewriten and my changes are lost.
I’m hoping there is a source file somewhere in the trixbox that is used when rewriting the extension_additional.conf file.
If I can rewrite that file, my changes wont be lost.
If this is correct, what and where is that filed located?
