DigiPBX by MD3 Communication Service, Inc.

PBX software for calls that need context.

Softphones, AI voice tools, Asterisk control, and custom systems built around the records, tasks, and follow-up that happen after the phone rings.

Two Tracks

Products and Custom Systems are equal paths.

DigiPBX can move as product development or as a tailored workflow build when PBX, records, and follow-up need to meet in one working surface.

Custom Systems

Custom Systems make the phone system part of the operating workflow.

The larger DigiPBX direction is phone-aware workflow software: click-to-call, caller context, case records, AI intake, notes, tasks, and follow-up in one place.

Custom system operating view Caller context before, during, and after the call
PBX event Incoming call matched

Route, extension, caller ID, and queue state become usable application context.

Record context Case / CRM screen pop

The operator sees the right customer, property, open case, and last note.

AI assist Structured intake

Call details can be summarized into fields, notes, and routing decisions.

Outcome Tasks + history

Follow-up stays tied to the record instead of living in memory or a side note.
