Small business IP phone

The Grandstream GXP1628 is a corded HD IP phone built for small business environments. It supports two SIP accounts and provides a 132 x 48 pixel backlit graphical LCD display for clear menu navigation. Three XML programmable context-sensitive soft keys adapt to different call states. Dual switched gigabit network ports with integrated PoE simplify cabling and power delivery.

Sustained call handling

The phone maintains full-duplex hands-free speakerphone operation with HD wideband audio during extended conferences. Its three-way conferencing capability stays stable without requiring external bridging hardware. An XML browser allows custom applications to run directly on the device throughout the workday. EHS support keeps compatible Plantronics headsets active for long shifts without manual reconnection.

Gigabit port and memory limits

Dual gigabit Ethernet ports pass traffic at line rate but do not exceed the gigabit standard. The phonebook stores up to 500 contacts and the call log holds up to 200 records, after which older entries are overwritten. Only two SIP accounts can be registered simultaneously, limiting multi-line configurations. The 132 x 48 pixel display resolution fixes the amount of on-screen information at any time.

Questions about this item

How much power does the GXP1628 draw when it runs all day on PoE?

The phone uses integrated PoE, so it receives power and data through the same Ethernet cable without a separate adapter.

What network infrastructure must already be in place for the dual gigabit ports to function?

A gigabit-capable switch or router with at least one free Ethernet port is required to connect the phone and pass through to a PC.

Will the 132x48 backlit LCD and 500-contact phonebook work with an older SIP server?

The phone supports two SIP accounts and standard XML browser features, so it registers with most SIP-based PBX systems.
