Headset Operations - Nortel DMS-100 Series Installation, Operation And Maintenance Manual

Headset operations

The M5216 set is compatible with several commercially available headsets that
use an RJ-type modular connector (electret microphones). When a headset is
connected, the hook switch is completely disabled—taking the handset off- or
on-hook has no affect on the status of the call. The Handset can be used for
speaking, however, and the Handset Mute function can be used for muting (see
"Handset operation and Mute control" for further details).
A summary of headset operations is provided in Table 3-3.
