The hosted phone system rides your internet line, so that connection is the real coverage question
Black Tie VoIP delivers its Cloud PBX and SIP trunks over the internet rather than a fixed line, so the service reaches any South African site with a stable connection while support stays anchored in Durban. Each concurrent call uses only around 100 kbps, so a reliable, low-latency line carries several calls comfortably and consistency matters more than raw speed. Because the voice and the connection can come from different suppliers, settling which line the phone system runs on, and how it is prioritised, is worth doing before you scale extensions.
- What does a Cloud PBX from Black Tie VoIP include?A Cloud PBX gives a small office the switchboard features it expects without on-site hardware, and Black Tie VoIP bundles auto-attendants, call recording and voicemail with a mobile app for taking business calls on a smartphone. Exactly which features and how many extensions you get are scoped per business, so confirm the inclusions against your call flow when you ask for a quote.
- Does Black Tie VoIP work outside Durban?Yes. The service is cloud-delivered, so it reaches businesses in Johannesburg and Cape Town as well as Durban, with support run from the Durban base. For a multi-site business that means the same phone system can span branches, though it is worth confirming how on-site help is arranged for locations away from the home base.
- Can staff take calls on their phones?Black Tie VoIP offers a mobile VoIP app, so staff can make and receive business calls on a smartphone using the company number rather than a personal line. That suits hybrid and on-the-road teams, and the app sits alongside desk phones on the same Cloud PBX so a business can mix the two as it prefers.
- Does the phone system keep working during load-shedding?A hosted phone system keeps running while the router and internet line at your office have battery or UPS backup, and the mobile app keeps the business number reachable on a charged phone with mobile data. A small power buffer on the router plus the app is the practical combination for staying contactable through a slot.
