Why 14 lines matter at the switchboard

When five or six calls ring at once, you want a key for each one so you can park it on hold and come back without confusion. The 14 line keys allow exactly that, and each SIP account can point to a different PBX or number, such as customer service, sales and management lines.

Grow to 160 keys with GBX20 modules

Each GBX20 has 20 physical keys across two pages, giving 40 multi-purpose keys per module. Chain up to four and you reach 160 keys for monitoring a whole building's extensions. Modules are sold separately, so you can start with the phone alone and add one roughly every 40 new staff.

Display and audio

A 1280x720 resolution on a 5-inch panel keeps names sharp and menus readable even from an angle across a reception counter. The handset and speakerphone deliver HD wideband audio, with dual microphones and Noise Shield technology to reduce waiting-room noise. For long shifts it supports Bluetooth headsets, USB headsets and an RJ9 jack with EHS for Plantronics.

Uses in Saudi Arabia

• Hospital switchboards, public and private, tracking hundreds of extensions with GBX20 modules.
• Reception desks in Riyadh office towers and business complexes handling lines for several tenants.
• Hotels in Makkah and Madinah during peak season, where one operator juggles many simultaneous calls.
• Small contact centers where a supervisor watches the team on BLF keys.

Compatibility and management

It works with Grandstream UCM PBXs and other standard SIP platforms. Management runs through GDMS, TR-069 or encrypted XML files, and security covers secure boot, dual firmware images and encrypted data. Power comes from 802.3af PoE or the 12V adapter in the box.

GRP2650 or GRP2670?

Both accept four GBX20 modules. The GRP2670 brings a 7-inch touch screen but has 12 lines and 48 virtual keys, against 14 lines and 56 virtual keys on the GRP2650. Pick the GRP2650 for an operator who works by buttons, and the GRP2670 for someone who prefers touch navigation.
