Some VoIP systems do have a number for sending your call to voicemail, We don't have one i'm afriad.
You say you're looking for calls to go to voicemail on busy but it sounds like your boss does not want call waiting disabled? If call waiting is turned on then your phone will never be busy, it will always be classed as being available.
I will find out how to turn off call waiting on those phones, I think it may only be possible on some firmware versions. I will have the information posted here:
