Case study

magicJack HOME: a Linux phone system from USB and SIP protocol research

magicJack HOME is investigated through its vendor macOS driver, USB register interface and captured SIP traffic to build a Linux-controlled analog phone endpoint. Python tools drive line power, ringing, hook detection and DTMF over hidraw, while baresip and a bridge connect the handset to a self-hosted PBX. The author reports live two-way calls on the resulting setup.
