Black Tie VoIP is a Durban and Cape Town-based South African VoIP and business telephony provider, operated by Nish Trading Enterprise (Pty) Ltd. We supply VoIP landlines, SIP trunking, telephone numbers and connectivity services to small and medium businesses across South Africa, directly and through our reseller network.

Our services let a business replace a traditional landline with internet-based calling, keep its existing number, and manage calls more flexibly without expensive legacy telephony hardware. Contact the Black Tie VoIP team to request a quote.

Black Tie VoIP is built for small and medium businesses (SMEs) in South Africa that want reliable, affordable business phone lines, including offices, professional practices, schools, retail and service businesses, and storage and logistics operations.

We also work with resellers and IT service providers who want to offer VoIP to their own customers through our reseller programme at voipreseller.co.za. Whether you are a single-site business with a handful of lines or a growing company with several branches, we can size a solution to fit.

Black Tie VoIP differs from traditional landline providers such as Telkom by delivering business telephony over the internet instead of copper lines, giving SMEs more flexibility on numbers, features and monthly costs, plus direct support from a local South African provider based in Cape Town.

With VoIP you can add or remove lines quickly, take your number with you if you move premises, and often pay less for calls than on a traditional line. We focus on SMEs, so you deal with a provider that understands South African business needs, from load shedding to local number requirements.
