Grandstream GBX20 Expansion Module
Grandstream GBX20 adds 40 programmable multi-purpose keys to Grandstream GRP2615 or GXV3350. Power users and receptionists will love the extra keys for BLF, speed dial, call park, presence, intercom, and more. The 4.3" color LCD display and 20 keys with multicolor LEDs make using GBX20 intuitive and simple. Because you have two pages for 20 keys, you get 40 keys in total.
You can daisy-chain up to four Grandstream GBX20 modules to add up to 160 extra keys. If you use one GBX20, you can power the expansion module through the host phone. If you use two to four modules, you can power them using the included power supply.
