Grandstream GXP1630 HD IP Phone
The Grandstream GXP1630 sits at the top of the long-running GXP16xx family. Three lines and three SIP accounts give a user room to hold, take and still have a line spare, eight BLF keys cover the colleagues they transfer to most, and 4-way conferencing handles small ad-hoc meetings without touching the PBX.
The practical details are what keep it in service: a slightly larger 132 × 64 backlit display, Gigabit ports on both sides so the desktop PC is not throttled, and built-in PoE so a single cable does the job. It remains a sensible small-business phone for supervisors and busy administrators, and it provisions in bulk through TR-069 or encrypted XML like the rest of the range.
Ideal for
- Supervisors and administrators juggling several calls at once
- Small business owners covering more than one number
- Reception positions in smaller offices
- Sites with Gigabit cabling and PoE switching already in place
- Teams that hold short conference calls from the desk
- Practices, clinics and workshops with a small internal team
Key features
- Three lines with three SIP accounts — three call appearances for genuinely busy desks
- Eight BLF keys — monitor colleagues and transfer with one press
- 4-way audio conferencing — the largest conference in the GXP16xx family
- 2.98-inch 132 × 64 backlit LCD — more display area than the rest of the range
- Dual Gigabit Ethernet ports — full network speed for a daisy-chained PC
- Built-in 802.3af Class 2 PoE — single-cable installation
- Three dual-colour LED line keys — instant line state at a glance
- 1000-entry downloadable phonebook — XML or LDAP directory from your platform
- Wideband G.722 audio — clearer internal speech than narrowband-only phones
- 256-bit AES, TLS, SRTP, HTTPS and 802.1x — secure provisioning and media

Frequently asked questions
How many calls can the GXP1630 handle at once?
Three lines with three call appearances, so a user can hold two calls and still answer a third.
Does it support 4-way conferencing?
Yes. It is the only GXP16xx model with 4-way audio conferencing; the others offer 3-way.
Are the ports Gigabit?
Yes, both switched ports are 10/100/1000 Mbps, so a PC connected through the phone is not slowed down.
Is PoE built in?
Yes, IEEE 802.3af Class 2. A mains adapter is only needed where PoE is not available at the desk.
What is the modern equivalent?
The GRP2613 is the closest current-generation model, offering a 2.8-inch colour screen, six line keys, up to 24 digital BLF positions and GDMS provisioning.
