Q1.
Is it true that the TDI-501 headset works on many keysets without the
need for an additional amplifier?
A.
Yes. We use a technology that matches the circuit requirements of the
handset’s microphone. The TDI-501 works on many modern phone
systems WITHOUT an amplifier, including 3 Com, Alcatel, Lucent,
Comdial, GE, ESI, Mitel, NEC, Nortel, Panasonic, Samsung, Siemens and
Toshiba. And Please visit tdiheadsets.com for full compatibility
