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