Grandstream GXP1628 HD IP Phone

The Grandstream GXP1628 is the GXP16xx model that earns its place on a busy desk. Alongside the familiar two lines and 2.95-inch backlit display it carries eight dedicated BLF keys, so a user can see which colleagues are free and transfer to them with one press rather than looking up an extension.

It also moves the network ports up to Gigabit and adds integrated 802.3af PoE, which removes the two most common complaints about budget handsets: a PC throttled to 100 Mbps and an adapter cluttering the desk. For reception overflow, small team leaders and anyone who transfers calls regularly, it is a noticeably more capable phone than the GXP1620 or GXP1625 for a modest step up in price.

Ideal for

• Small reception and front-desk positions
• Team leaders and supervisors transferring calls regularly
• Sales and support staff monitoring a handful of colleagues
• Sites with Gigabit cabling that cannot accept a 100 Mbps phone
• Offices cabled for PoE with no spare mains sockets
• Practices and clinics with a small internal team to reach

• Dual Gigabit Ethernet ports — the PC behind the phone keeps full network speed
• Integrated 802.3af Class 2 PoE — one cable to the desk, no adapter needed
• Two dual-colour LED line keys — clear visual state for each line
• 2.95-inch backlit graphical LCD — readable in poorly lit offices

• Thirteen dedicated function keys — everyday actions stay a single press
• 1000-entry XML or LDAP phonebook — company directory pushed to every phone
• RJ9 headset jack with EHS — Plantronics electronic hook switch support
• TLS, SRTP, HTTPS and 802.1x — with 256-bit AES encrypted configuration files
