We are using snomONE in a school as a pilot. I've had the request to change the sound the phones produce when someone intercoms their phone. Since this is in a classroom, it can be rather loud and it would be nice if it could be changed to something more attention grabbing. Any ideas? I found sounds in the audio_mohs folder, but that didn't seem to contain the file I might want to change. Thanks for you help in advance!
