BCM50 Voice Call buzzer issue

[MPJ1228]

I have a customer who has a BCM50 and one of the IP phones buzzer is extremely loud when you voice call...It is the only phone that is really loud and can't find where to lower that sound. None of the other phones have this issue but this one sounds like a fog horn. Does anyone have any ideas? I read up about going through the main menu from the phone but the audio menu isn't shown as an option.

Do Feature *6 on the set, it will allow you to change the ring type and volume.

Sorry forgot to read "voice call". Try to lower the volume while someone voice call to it using the volume bar.

I've tried both above before and no change. Is there anything on the sytem side that allows to change the buzz volume? I read a manual but says something about having administrator access?
