Multiline Terminal .
Headsets that have open style receivers (i.e., Mirage, Duoset and
Duopro) can cause echo problems on ITH-8D/16D-2 telephones.
The echo suppression and receiver gain of the telephone determines
the severity of the echo when using any headset.
Due to the environment where the telephones or headsets are
located, ambient noise may affect performance. Please contact NEC
for the recommended headset to use with VoIP applications.
