Teams telephony and Alcatel support in the same shop
CBX covers an unusual span for one supplier. At one end it supports Alcatel systems, which is legacy enterprise telephony that many companies still run and that fewer and fewer integrators will touch. At the other it does Microsoft Teams telephony integration, which is where a lot of those same companies are heading. If your organisation is somewhere in between, running an installed PBX while planning a Teams migration, a supplier that handles both ends of that road is worth a conversation. The infrastructure side is genuinely relevant rather than padding, because Teams voice quality is decided by the network as much as the licensing, and having the WiFi, switching and cabling from the same team removes the argument about whose fault the call quality is. Ask what the 600 regional sites figure actually represents, and how a fault at a branch outside Gauteng gets attended to. Compare alternatives in the cloud PBX directory.
Who CBX is a fit for
- Companies running Alcatel systems that still need proper support
- Businesses moving voice into Microsoft Teams and needing the network fixed too
- Multi-branch operations wanting telephony and cabling from one supplier
