What is vmDigitPatternOnBusy?

This OID specifies the digit pattern string (up to 119 characters) sent from PBX to voicemail to indicate the destination was busy. The voicemail system recognizes this pattern and selects a busy-specific greeting. Setting it to '*21' ensures voicemail tells the caller 'the extension is busy; please leave a message.'
