Enterprise Solutions for BIG Telephony


We love nothing more than creating new applications for new ideas. Customisation and integration is the primary focus point for the majority of enterprise and development projects. Typical requirements include management platforms to unify voice and related services, commercial elements like automated billing, prepaid and postpaid models, self-service portals for resellers and sub-customers, cloud and hosting elements, converting outdated hardware clusters to single virtual clusters, high performance VoIP termination services, multi-tenant solutions, call centre solutions and other unique requirements.


BiZVoIP multi-tenant solutions offer a high level of unification through its one-for-all design. Unlock a new level of time-saving efficiency and always-on technology.


Software development and integration is what we do best. BiZVoIP API integration available for Cloud PBX, Carrier VoiP, AVM, API Dialer and Bulk SMS. Other specialised APIs also available.


Looking at past trends to predict the future and using software to replace human elements are some of the methods we use to ultimately increase efficinecy and simplicity.
