Insights

Hospitality properties often look for phones that balance guest-friendly usability with the flexibility staff need to configure hotel-specific features, such as direct lines to reception or room service. The GHP621 addresses this with 6 programmable keys, giving properties more room to map out these shortcuts than more basic hotel phone models offer, while still keeping the interface simple enough for guests to use intuitively.

Its added USB-C port also reflects a practical guest amenity: rather than searching for an outlet, guests can charge a phone or other small device directly at the same spot where the room phone sits, a small convenience that can meaningfully improve the in-room experience.

Is It Right?

This hotel phone is a great choice if you:

• Want more programmable keys than an entry-level hotel phone offers.
• Manage a hospitality property and want simple, PoE-based installation.
• Want to offer guests a convenient USB-C charging point.
• Need centralized provisioning and monitoring across many rooms.
• Prefer a wired network connection over Wi-Fi for reliability.

You may want to consider another option if you:

• Need built-in Wi-Fi connectivity, since the GHP621 requires a wired Ethernet connection (see the GHP621W for wireless).
• Prefer a white finish, since the GHP621 comes in black (see the GHP620 for white).
• Require more than 2 SIP accounts for advanced call routing.
