GBX20 delivers additional functionality, versatility and exibility to Grand-
stream GRP2615 Carrier-Grade IP Phone or GXV3350 High-End Smart
Video Phone for AndroidTM. The GBX20 module features a large 480x272
graphic LCD and 20 programmable buttons (each with dual color LED). In
addition, it allows up to 40 extensions per module 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, powered, and controlled by the
GRP2615/GXV3350, providing the benets of the additional keys instantly.
The GBX20 supports the traditional call features on each of its program-
mable buttons, including BLA (bridged line appearance)/SCA (shared call
appearance), BLF (busy lamp eld, standard or eventlist), Call Park/Pick-
up, Speed Dial, Presence, Intercom, and conference/transfer/forward. The
GBX20 is the ideal solution for o󰀩ces that manage high call volumes or an
o󰀩ce receptionist. By using the GBX20 the telephone attendant can ensure
maximum o󰀩ce productivity by e󰀩ciently monitoring and dispatching multiple
incoming calls.
