Kenyan SMEs retiring analogue PABX extensions, contact centres in Westlands and Kilimani, SACCO branch counters, hotel front desks in Diani and Naivasha, law firm receptions, and hospital switchboards all face the same desk problem. A receptionist needs to see who is free before transferring a call, and a cramped desk rarely has a spare power socket or a second network drop. The Grandstream GXP1628 answers both. Its eight BLF keys show green or red at a glance, and its second Gigabit port feeds the desktop PC through the phone, so one cable run serves two devices.

Unlike other electronics retailers in Kenya who stock only 100Mbps entry handsets, Mascom International supplies the Grandstream GXP1628 with true dual-switched 10/100/1000 Mbps ports, so a workstation plugged behind the phone still reaches full Gigabit LAN speed. Users consistently report that the Grandstream GXP1628 registers against 3CX, Asterisk, FreePBX, Yeastar, and Grandstream UCM servers within minutes of provisioning. Walk into our Kimathi Street store to lift the handset and test the speakerphone in person, or order the Grandstream GXP1628 for pay-on-arrival delivery to any of Kenya's 47 counties.

The GXP1628 is a 2-line Gigabit desk phone for small and mid-sized businesses running voice over their data network instead of copper lines. It suits receptionists, account managers, front-office staff, and contact centre agents who handle 30 to 100 calls daily. The 8 BLF keys make it the natural choice for anyone who transfers calls constantly. Offices with fewer than 25 extensions, branch counters, and departments inside larger installations get the most value from this model at KSh 9,000 per desk.

Yes. The Grandstream GXP1628 speaks standard SIP as defined in RFC 3261, so it registers with any SIP trunk or PBX sold in Kenya. That covers Safaricom Business voice services, Airtel Kenya SIP trunks, and hosted platforms resold locally. On-premise setups running Asterisk, FreePBX, Issabel, 3CX, Yeastar, or Grandstream's own UCM6300 series work equally well. With a UCM PBX the phone provisions through Zero Config, meaning the server pushes settings automatically once the handset appears on the LAN.

BLF stands for busy lamp field. Each of the 8 dual-colour keys is mapped to a colleague's extension and lights up when that person is on a call. Your receptionist sees at a glance that the finance manager is engaged and the sales lead is free, then transfers the caller with a single press instead of dialling an extension and waiting. Offices report this cuts transfer time to roughly three seconds and removes most misrouted calls during the 9:00 AM rush.

Both options ship in the box. The GXP1628 supports IEEE 802.3af Class 2 Power over Ethernet, drawing between 3.84W and 6.49W from a compatible switch, so one cable carries data and power together. That matters in Kenyan offices where desk sockets are scarce and load shedding is real, because a PoE switch on a UPS keeps every phone alive during an outage. A universal 100-240V adapter with a 5VDC 600mA output is also included for desks without PoE.

The GXP1610 handles a single SIP account on 10/100 Mbps ports with no BLF keys. The GXP1625 adds PoE and a colour-free second line but stays at 100 Mbps. The GXP1628 is the only model in the entry range combining two SIP accounts, 8 BLF keys, and dual Gigabit ports. If your desktop PC shares the phone's network drop, the Gigabit pass-through alone justifies the difference, since a 100Mbps port would throttle file transfers across your office server.

Voice quality holds up well because the GXP1628 supports the G.722 wideband codec, which carries roughly double the frequency range of standard narrowband calling. Internal calls between two GXP1628 handsets on the same LAN sound noticeably fuller. On external calls over Safaricom Home Fibre, Faiba, or Zuku links, the phone falls back to G.729 or G.711 and uses acoustic echo cancellation, packet loss concealment, and an adaptive jitter buffer to smooth out unstable bandwidth.

Yes, and this is where the model earns its keep on larger rollouts. The GXP1628 supports mass provisioning through TR-069, AES-encrypted XML configuration files served over HTTPS, and FTP or FTPS. Your IT team builds one configuration template, hosts it, and every handset pulls its extension, dial plan, and directory on first boot. With a Grandstream UCM PBX, Zero Config does the same job with no external server. A 50-desk deployment becomes an afternoon task rather than a week.

For a Gigabit-capable business handset, yes. Comparable 2-line Gigabit phones from Yealink and Fanvil typically sit higher, and cheaper 100Mbps units force a second network drop for every PC or throttle that connection. Across a five-year service life, KSh 9,000 works out to under KSh 5 per working day per desk. Add the LDAP and XML phone book holding 1,000 contacts, 200 call records, and wall-mount hardware, and the cost per desk stays low.
