Figure 1. Voicemail system using a DMI4
When a call is destined for the voicemail system, the PBX selects one of the digital lines assigned to
voicemail and uses it to send information concerning the call, such as where the call originated, where the
call was initially intended to terminate, and why the call was sent to voicemail instead. In the event that the
call was placed directly to the voicemail system (to the pilot or prime number), the PBX also indicates that it
was a direct call.
