Yealink SIP-T20 IP Phone with 2-Lines and HD Voice - Not PoE

Yealink SIP-T20 IP Phone with 2-Lines and HD Voice - Not PoE

Q: Do the regular phone jack (rj9) connectors on the base work for any regular wireless headset (like AT&T)?

the short answer is "kind of". it depends on the headset type but the headset must be plugged into the headset jack. you cannot plug the headset inline with the handset. many of the older headsets were connected between the handset (the thing you hold in your hand) and the base unit of the phone. this type of connection does not work on most SIP phones. Yealink also offers an adaptor for certain handsets that enable you to answer a call from the headset. the other thing to note is that depending on the headset model you might need to change the pin outs on the rj9 connector.
