Yealink EXP 20 Expansion Module for T27P/T29G (End of Life)

The Yealink EXP 20 is an add-on for specific Yealink IP phones that expands your calling abilities giving you two extra lines with adjustable stands, so you can see more information and manage more calls at once. You can connect up to six of these modules to a single phone for even more lines. The EXP 20 gets its power either from the main phone itself (for two or fewer modules) or from a separate power supply (needed for more than two modules).
