United Voice Cloud Hosted PBX

A hosted telephone solution means your business’s phone system is stored in the “cloud”. This comes with a number of advantages including limiting the amount of hardware required at your business premises and enabling your employees to receive calls anywhere in the world. Hosted PBX Phone Systems use regular internet rather than traditional copper lines to send and receive high-quality calls, meaning that your organisation no longer needs to use Telkom for line rentals or telephone numbers.

Frequently Asked Questions

As with an on-premise PBX, a Hosted or Cloud PBX System provides your business with communication features such as call-transfer, on-hold, auto-attendant, voicemail, call forwarding and more. The difference with a Cloud Hosted PABX, is that it is hosted at an offsite data center and is powered and managed through the internet as opposed to copper landlines.
