Evergreen, and what to check before believing it
“Evergreen” and “pay-as-you-go” are the two claims doing the work here, and both are worth testing at quote stage. Evergreen should mean you never again build a business case for a PBX upgrade, because the platform updates underneath you — ask whether that includes major version changes and whether any of them carry a professional-services fee. Pay-as-you-go should mean seats flex down as well as up; ask what the minimum commitment actually is. The wider stack matters too: with connectivity, security and even solar under one roof, this suits a business that wants one accountable supplier and suits nobody who wants to keep each layer competitively tendered.
Who Open Communications is a fit for
- Businesses wanting phones, connectivity and security from one Cape Town supplier
- Microsoft-centric offices that want calling inside Teams rather than a separate app
- Companies that would rather flex seats monthly than sign a fixed multi-year PBX deal
