Grandstream GXP1628 Gigabit IP Phone | 2 Lines & 8 BLF Keys
Grandstream GXP1628: A Powerful Gigabit IP Phone for Everyday Productivity
The Grandstream GXP1628 brings an efficient call environment to any desktop. It is a powerful Gigabit IP phone designed for small to medium businesses, delivering an intuitive and essential desktop communication experience. This Linux‑based phone combines a clear 132×48 backlit LCD display, 2 lines/SIP accounts, and 8 dual‑color speed‑dial or BLF keys, making it perfect for users who handle low to medium call volumes and require quick access to colleagues.
The BLF keys are a standout feature, allowing you to monitor the presence/status of other extensions and see incoming transfer calls easily. This significantly improves receptionist or team efficiency, as you can see at a glance who is on a call before transferring.
Crystal‑Clear HD Audio & Advanced Telephony
The GXP1628 is equipped with HD wideband audio hardware and software support for the G.722 codec, ensuring crystal‑clear, natural conversations on both the speakerphone and handset. Advanced telephony features include:
-
Full-duplex speakerphone with advanced acoustic echo cancellation
-
500‑contact phonebook (downloadable via XML/LDAP) and 200‑record call history
Built for Speed & Simplicity
Unlike basic phones with standard Fast Ethernet, the dual 10/100/1000 Mbps Gigabit PoE ports provide maximum network speed and performance for both the phone and your PC, with no compromise on voice quality. Integrated PoE (802.3af) allows the phone to be powered directly from your network switch, reducing cabling clutter.
Enterprise‑Grade Security & Provisioning
The GXP1628 features state‑of-the-art security encryption, including SRTP and TLS, to protect your calls and accounts. It supports automated provisioning via TR‑069 and encrypted XML configuration files, enabling zero‑touch mass deployment across your entire organization.
Why Choose the GXP1628?
If you need a phone that feels responsive and handles slightly busier workflows with features like BLF monitoring and Gigabit speeds, the GXP1628 is the clear choice over simpler entry‑level models. For a more compact and budget‑friendly option with similar features but a slightly smaller set of extra keys, you can compare it with the GXP1630 model.

Frequently Asked Questions
Q1: What are the main differences between the GXP1628 and the GXP1625 I already have? +
The GXP1625 offers similar 2‑line support with PoE but only includes 8 additional BLF keys and operates with basic 10/100 Mbps network ports. The GXP1628 upgrades to dual 10/100/1000 Mbps (Gigabit) interfaces. This key difference makes the GXP1628 significantly faster and more suitable for data‑intensive environments than the standard GXP1625.
Q2: How does the GXP1628 help with handling multiple incoming calls for a receptionist? +
Its 8 BLF keys are invaluable for monitoring the real‑time status (busy/idle/ringing) of other extensions. This allows a receptionist to see who is available before transferring a call, dramatically improving response times and reducing customer frustration.
Q3: What type of power adapter does the GXP1628 require for Pakistan? +
The GXP1628 supports integrated PoE (802.3af) . If you are not using a PoE switch, a universal AC power adapter is included that accepts an input of 100-240VAC, 50/60Hz – working perfectly on Pakistan's standard 220V/50Hz grid.
Q4: Does the GXP1628 support remote management if I have multiple offices? +
Yes. The phone supports TR‑069 and encrypted XML configuration files, allowing for zero‑touch mass provisioning and remote firmware updates. This is ideal for integrators or businesses managing multiple sites.
