The Grandstream GXP1628 is a small-business VoIP desk phone with two SIP accounts, suited to office users who need straightforward calling and support for multiple lines.
Recommended For
- Small-office staff who make and receive calls from a fixed desk and want a straightforward SIP phone with two accounts, HD handset and speakerphone audio, and basic call handling.
- Receptionists and office coordinators who regularly check colleagues’ availability or transfer calls; the eight BLF/speed-dial keys can show extension status and provide quick access.
- Small businesses deploying several compatible desk phones, especially those using Grandstream UCM, that want PoE and automated provisioning options for setup and management.
- Desk-based workers who occasionally need a small group call; the phone supports three-way conferencing.
