Grandstream GXP1625 HD IP Phone
The Grandstream GXP1625 is the Power over Ethernet member of the GXP1620 pair. Two dual-colour line keys, a 2.95-inch backlit LCD and two SIP accounts cover everyday office calling, and the built-in PoE means the only thing arriving at the desk is a single network cable.
For anyone fitting out a floor, that saves a socket per position and makes remote power-cycling possible from the switch. HD audio, 3-way conferencing, a 1000-entry downloadable directory and 256-bit AES encrypted provisioning make it a dependable general-purpose handset for offices, schools and shared workspaces that want low cost without a phone that feels like a compromise.
Ideal for
- Office fit-outs where every desk is cabled for PoE
- Schools, colleges and training facilities
- Shared workspaces and serviced offices
- Desks with no accessible mains socket
- Meeting rooms and common areas
- Hosted providers supplying a low-cost PoE handset as standard
Key features
- Built-in Power over Ethernet — one cable delivers data and power to the desk
- Two dual-colour LED line keys — see line state without reading the screen
- 2.95-inch backlit graphical LCD — legible in poorly lit rooms
- Two SIP accounts with two call appearances — hold one call and take another
- Three XML programmable soft keys — context-sensitive functions above the display
- Thirteen dedicated function keys — hold, transfer, conference and the rest are one press
- 3-way audio conferencing — add a third party without a bridge
- 1000-entry XML or LDAP phonebook — push a company directory to every handset
- RJ9 headset jack with EHS — Plantronics electronic hook switch support
- 256-bit AES configuration encryption and 802.1x — safe provisioning across untrusted networks

Frequently asked questions
Does the GXP1625 need a power supply?
Not if the desk has a PoE switch port. PoE is built in, so a mains adapter is only needed where PoE is unavailable.
What is the difference between the GXP1620 and GXP1625?
Power only. Both have the same two lines, backlit display, keys, directory and codecs; the GXP1625 adds built-in PoE.
Will a PC plugged into the phone get full speed?
The ports are 10/100 Mbps, so a daisy-chained PC is capped at 100 Mbps. For Gigabit, choose the GXP1628 or GXP1630.
Can I add BLF keys?
Not on this model. The GXP1628 provides eight dedicated BLF keys in the same family.
Is it suitable for a school rollout?
Yes. Low cost, PoE power and bulk provisioning over TR-069 make it a common choice for education sites.
