More product details
The Grandstream GXP1628 is best suited for small offices or home offices where the phone is used for moderate call volume. Its two-line capability and eight BLF keys make it a reasonable fit for a receptionist or a user who needs to monitor a few colleagues' extension status without requiring a full-blown operator console. The integrated PoE simplifies cabling in environments where power outlets near desks are scarce, and the dual gigabit ports ensure the desktop PC does not lose network speed thanks to a pass-through connection.
This phone pairs well with a range of hosted VoIP providers popular in Canada, including those that rely on standard SIP trunking. It can replace an older single-line desk phone where basic features like three-way conferencing and HD audio are now expected. The display is a modest monochrome LCD—fine for viewing caller ID and menus but not for heavy graphical use. The handset and speakerphone deliver clear wideband audio, though the microphone may pick up room noise in very open spaces.
The GXP1628 does not include a built-in Wi-Fi, so a wired drop is required. Its two-line capacity may feel limiting for a user who handles multiple active calls simultaneously; a four- or six-line model would be more appropriate in that case. For a single-user desk in a quiet office, however, this phone offers good value without over-engineering the feature set. In a larger deployment across the GTA, these phones work reliably with most hosted PBX platforms, and their TR-069 support makes remote provisioning straightforward for a VoIP support provider.
