Expansion Module for T46S/T48S


EXP40 expansion module for use with T46S/T48S, mono screen and dedicated page view keys

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.
