The Nortel Companion system uses Companion C3060 Portable Telephones. Each portable telephone has a unique identity that must be registered on the Controller, allowing only pre-authorized people to use the system.

The C3060's combination of digital technology and noise-canceling microphone provide clean, clear audio quality indistinguishable from that of a desk telephone. With Companion, none of the interference, crackles or buzzes that can occur with cellular phones come between you and your conversation.
