OVERVIEW:

GBX20 delivers additional functionality, versatility and flexibility to Grand-

stream compatible phones (GRP2615 & GXV3350). The GBX20 module fea-

tures a large 480x272 graphic color LCD or and 20 programmable buttons

(each with dual color LED). In addition, it allows up to 40 extensions per mod-

ule by using the 2 page switch keys and up to 160 buttons when 4 extension

modules are daisy-chained together. The GBX20 module is connected, pow-

ered, and controlled by the GXV3350/GRP2615, providing the benefits of the

additional keys instantly. The GBX20 supports the traditional call features on

each of its programmable buttons, including BLA (bridged line appearance)/

SCA (shared call appearance), BLF (busy lamp field, standard or eventlist),

Call Park/Pick-up, Speed Dial, Presence, Intercom, and conference/transfer/

forward. The GBX20 is the ideal solution for offices that manage high call

volumes or an office receptionist. By using the GBX20, the telephone at-

tendant can ensure maximum office productivity by efficiently monitoring and

dispatching multiple incoming calls.
