This 2019 TSG-certified Avaya J179 Secure VoIP Phone is an engineering sample from Avaya, a company with a long connection to the telecommunications industry.

The phone was received at the Old Telephone Room on October 13, 2022, from a former Bell-Northern Research (BNR) / Avaya engineer. Its TSG certification and engineering-sample status make it an interesting example of the security-focused business telephone technology developed in the late 2010s.

This phone is part of the Old Telephone Room’s personal collection, preserving another piece of the continuing history of telecommunications equipment.
