Voice Services SP1/2 have an X_RingProfile setting. By default Profile B is for Australian tones, which means if you dial out you will hear different dial, busy or ring tones using that profile.
It is similar to the British system with a 'double ring' incoming and outgoing.
You can manually edit the individual tones, too, by copying and pasting.
Putting back the checkmark will restore the default if you make a mistake.
Read Tone & Ring Patterns in the Admin. Guide.
