Grandstream GHP631 Hotel IP Phone with 3.5-inch Color LCD and PoE

The Grandstream GHP631 is a black guest-room phone with a 3.5-inch color screen (480×320), 2 SIP lines, 10 speed dial keys and 6 soft keys, powered over PoE. It is aimed at suites, premium rooms, serviced apartments and patient rooms.

====

The Grandstream GHP631 gives the guest-room phone what it usually lacks: a screen. You get a 3.5-inch 480×320 color display, 2 SIP lines, 10 speed dial keys and a PoE network port. Guests see who is calling and spot a message from the front desk at a glance. It is a natural fit for suites, premium rooms, serviced apartments and private patient rooms.

Grandstream GHP631 key specs

A black phone for desk or wall mounting, with these essentials:

• 3.5-inch color LCD, 480×320.
• 2 lines and 2 SIP accounts, with 6 soft keys alongside 10 speed dial keys.
• One 10/100 Mbps port with integrated PoE (Class 2).
• USB Type-C port that charges devices at up to 500 mA.
• Full-band Opus with tolerance for up to 30% packet loss.

What the screen does for guests

An incoming call shows the caller's name or number, and the guest answers or ends it with an on-screen key. New voicemail triggers a pop-up and the green message light blinks; missed calls appear too. From the idle screen a guest can switch on Do Not Disturb, or sleep mode, which turns off the display and LEDs at night and wakes for any incoming call.

Soft keys that help staff too

In a suite or a floor office, a blind transfer takes one on-screen key, and the call comes back automatically if nobody answers. The contacts list opens right on the phone. The ten speed dial keys are set on the web page for reception, room service and the restaurant.

One cable, central management

The GHP631 runs from a PoE switch and ships without a power adapter. IT can provision it in bulk through GDMS, TR-069 or AES-256 encrypted XML, and it boots in about 15 seconds. Security includes secure boot, a unique per-device certificate, a random default password, SRTP, TLS and 802.1X. The handset carries HD audio and is hearing aid compatible.

Where it fits in Saudi Arabia

• Suites and executive rooms in hotels across Riyadh, Jeddah and Makkah.
• Serviced apartments that want a more modern look than a keypad phone.
• Private patient rooms in hospitals and medical centers.
• Guest housing on university campuses and residential compounds.

PBX compatibility

It works with any SIP PBX. On a Grandstream UCM it provisions itself and sets the room number as the main account. Multicast paging and Grandstream GDS door opening are supported. Note that the official menu languages are English, Spanish and French; Arabic is not listed.

GHP631 vs GHP621 vs GHP631W

The GHP621 has the same two lines with no screen, plus a swappable faceplate for your logo, which makes it the better pick for standard rooms. The GHP631W is the GHP631 with Wi-Fi 6 and a 12V adapter in the box, for rooms with no cable. Prefer white? Go for the GHP630.
