Gravity Office Solutions — PABX, VoIP and office automation provider in Sandton
Gravity Office Solutions has worked in digital office automation, ICT and solar power since 2007, operating from Fourways in Sandton. PABX and VoIP telephony sit inside a wider catalogue that runs to interactive boardroom and classroom screens, CCTV, cyber security, connectivity and backup power, which makes it a single-supplier proposition rather than a voice specialist.
Key facts
| Who they are | A South African company describing itself as “leaders since 2007 in the field of digital office automation, solar power and the ICT space”, offering turnkey solutions across office technology |
| Voice services | PABX and VoIP telephony, supplied and supported alongside the rest of the office technology stack |
| Also offers | Digital office automation, solar and backup power, interactive boardroom and educational screens, CCTV and security, cyber security, and internet connectivity |
| What that means for you | Voice is one line in an office-technology business rather than the core trade. That is efficient if you want the phones, the screens, the cameras and the inverter from one supplier with one account manager, and it is a reason to ask specifically which platform the phone system runs on and who supports it |
| Solar and backup power | An unusual pairing with telephony, and a practical one in South Africa: the same supplier can size the backup power that keeps your phone system and router alive during an outage. Ask for the phone system and its power protection to be quoted together, since a cloud PBX without power is just a dead handset |
| Head office | 102 Leslie Avenue, Fourways, Sandton, 2000, Gauteng, per the company Google Business Profile. The website itself publishes no street address |
| Coverage | South Africa, operating from Gauteng |
| Pricing | Quote-based. No figures are published for telephony or any other line |
| ICASA licence | No ICASA reference is published. For a reseller supplying phone systems this is normal — ask which licensed operator carries the calls |
| Customer rating | 3.9 from 15 Google reviews, on a profile matching the company’s domain and published phone number exactly. A mixed score rather than a strong one, and the profile has been active recently, so ask for two reference customers running the same phone platform you are being quoted |

The phone system and the power that keeps it alive
Most South African buyers discover the flaw in a cloud phone system during the first extended outage: the platform is fine, the internet is fine somewhere else, but the router and the handsets on your desk have no power. A supplier that sells both the telephony and the backup power can size the two together, and that is the genuinely useful thing about this combination. Ask for it explicitly — how long the proposed battery holds the router, the switch and the phones, not just how long it holds the lights. Nearly two decades in office automation is a reasonable track record, and the breadth is real: screens, cameras, cyber security, connectivity and power alongside the PABX. The trade-off is the familiar one for a generalist. Voice engineering depth is worth testing, so ask which platform the phone system runs on, who configures it, and what happens when the person who knows your setup is unavailable. The 3.9 rating across fifteen reviews is middling rather than alarming, and the right response to a middling score is specificity: ask for two reference customers running the same phone platform at a similar size, and speak to them. Compare voice specialists in the cloud PBX directory.
Who Gravity Office Solutions is a fit for
