Knowledge Base - Comparing Side Cars / Reception Modules (EXP20 / EXP40 / EXP43 / EXP50) [Yealink]

Yealink phones are divided into multiple series. Each series has a side car capable of adding more DSS keys to phones which may benefit from the additional one-button dial or extension monitoring capabilities.

Here we summarize that information:

Model Phones Max # Units Keys Pages Total Per Unit Max Keys
EXP20 T29G 6 20 (19*) 2 38 228
EXP40 T46S/T48S 6 20 2 40 240
EXP43 T43U/T46U/T48U 3 20 3 60 180
EXP50 T5x 3 20 3 60 180

* The EXP20 lacks dedicated page buttons - in multi-page mode, the bottom right key is used to switch pages.


  • Using multiple units may require additional power connection(s)
  • The unit is selected must match the supported phone model
