Two-line VoIP phone

The Grandstream GXP1628 is a VoIP desk phone that supports two SIP lines. It includes a built-in speakerphone and a single RJ-45 network port with PoE support. The unit can be powered by an AC adapter or through the network cable. Its compact footprint measures 192.50 mm wide and 76 mm high, weighing approximately 800 g.

Small-office users and multi-line needs

This phone suits small businesses or home offices that need two concurrent lines on a single device. It is not intended for users who require more than two SIP accounts or additional physical line keys. Buyers needing colour displays, Bluetooth, Wi-Fi or expansion modules should look at other models.

Two SIP lines

The defining specification is the limit of two SIP lines, which determines how many simultaneous calls or accounts the handset can handle. If your workflow demands three or more registered accounts, this model will not meet that requirement.

Questions about this item

Should I choose the GXP1628 with 2 SIP lines or a model with more lines?

The GXP1628 supports 2 SIP lines. Choose it if you need two independent accounts; pick a higher-line model only if your workflow demands three or more simultaneous registrations.

What does the 2 SIP line specification mean for daily use?

You can register two separate SIP accounts — for example a main line and a department line — and handle calls on both without switching profiles.

How does the single RJ-45 port with PoE affect placement?

The single RJ-45 carries both data and power, so the phone connects to a PoE switch or injector with one cable, simplifying desk or wall mounting.
