Grandstream DP722 Lightweight DECT Handset with Door Control

The Grandstream DP722 is a 110 g DECT handset with a 1.8-inch color screen that pairs with DP750, DP752 and DP755 bases and opens a GDS intercom door with one touch. It is a good match for clinic receptions, villas and offices where staff move between the desk and the entrance.

====

The Grandstream DP722 is a 110 g DECT handset that a receptionist or supervisor can keep in a pocket and use to answer PBX calls from anywhere in the building. It pairs with a Grandstream DP750, DP752 or DP755 base and reaches up to 350 m outdoors. What sets it apart from the DP720 is door control: its official page lists one-touch door opening with Grandstream GDS intercoms, so the handset doubles as a gate controller.

Why choose the Grandstream DP722

• 110 g with a 1.8-inch color TFT screen (128×160).
• Up to 20 SIP accounts and 20 lines with DP755; 10 with DP750 or DP752.
• 350 m outdoor range with DP752/DP755, 50 m indoors.
• 20 h talk and 250 h standby on two AAA cells.
• Configurable push-to-talk key and 3.5 mm headset jack.

Talk to the visitor, open the door

With a Grandstream door intercom such as the GDS3710 at the entrance of a villa, clinic or warehouse, the intercom rings the handset. You speak to the visitor and open the door with one touch, without leaving your spot. Reception staff stop walking to the gate every few minutes, and a villa owner can open the annex or courtyard door from inside the house.

It needs a DECT base

The DP722 is a handset, not a complete system. The base connects to the PBX over Ethernet and the handset links to the base by radio. The DP755 base takes up to 10 handsets and 20 SIP accounts. Pairing is simple: press the subscribe button on the base, then pick Register from the handset menu.

Clear calls and handy tools

Earpiece and speakerphone both support G.722 HD voice, with echo cancellation and noise reduction on the mic and on incoming audio. Call hold, transfer and forward, 3-way conferencing, intercom between handsets, a downloadable phonebook and a call log are all there. Menus are available in 21 languages, including Arabic, and firmware updates arrive over the air.

Typical uses in Saudi Arabia

• Clinic and medical center receptions with an intercom at the entrance.
• Villas and rest houses: answer the doorbell and open the gate from indoors.
• Small offices and branches where staff move between rooms.
• Warehouse entrances where a supervisor receives drivers.

Compatibility and management

The base registers to any SIP PBX, including Grandstream UCM6300 and Yeastar P-Series, so the handset shows up as a normal extension. IT can manage bases and handsets from one GDMS dashboard.

DP722 vs DP725

The DP722 runs on two AAA cells with 20 hours of talk time and a 350 m range. The DP725 uses a 1500 mAh lithium battery rated at 50 hours of talk, charges over USB-C with fast charging (10 minutes gives 4 hours of talk), reaches up to 400 m with a DP755, and adds a dedicated side push-to-talk key. Go with the DP722 for reception and office work, and the DP725 for long shifts.
