SwyxPhone Extension Modules

SwyxPhone Extension Modules are convenient extensions for the SwyxPhones L615, L640 and L660.

Depending on the model these extensions offer 12, 18 up to 24 additional function keys / speed dials and match to the respective SwyxPhones. Users can plug up to two extension to the right side of their SwyxPhones. What is very handy is the status signalling: LEDs with the speed dials show, which coworkers in your company are available and who talks at any given moment.
