The Yealink EXP40 expansion module features an elegant design that matches the appearance of the T4 range while its core function is to expand on the capabilities of the T46S/T48S. Ideally suited for receptionist use, the EXP40 expansion module can be “daisy-chained” with up to 6 expansion modules on a single phone. Two of the EXP40’s can also be powered by the host phone, simplifying setup. The two dedicated page view keys allow operators to flip through extensions/functions without using any of the physical line keys. Additional functions such as call park, forward, conferencing etc. can also be programmed. The EXP40 expansion module is a stylish and functional must have for businesses that require receptionists to handle calls.
