The XML conf files have been recently modified to replace "$${base_dir}/sounds" with $${sounds_dir}. The same replacement was done for $${base_dir}/recordings and $${recordings_dir}. In vars.xml, the X-PRE-PROCESS cmd to setting the old variable sound_prefix was removed but set commands were not added for the new variables sounds_dir and recordings_dir. How is FS finding determining the value of $${sounds_dir} and $${recordings_dir} in the XML files? I ask because I have 2 cloned FS servers where one can find sound files in the IVR when an invalid extension is entered, but the other does not and is using the wrong path to search for sound files.

The only difference I know of is Server 2 was originally compiled with mod_flite enabled but it is not loaded at runtime. Any suggestions why one server can find sound files but the other looks in the wrong path? Thanks, Robert
