EXP40 Expansion Module
The Yealink EXP40 is ideal for receptionists, administrative assistants, call center agents,
power-users, and executives who need to place a large volume of calls on a regular basis. When
your T48G is registered with a Skype for Business Server, you can assign contacts to EXP keys on
your EXP40, so that you can quickly call contact by pressing the corresponding EXP key. You can
also monitor your contacts’ presence status from your expansion module. For more information
on contact’s presence, refer to Changing Presence Status on page 26.
