Mini PBX systems are ideally adapted to companies who have more than 10 owners, but up to 100. Mini PBX provide access to features like voice mail, automated attendant, voice conferences, computer integration and call distribution.
There are 2 categories of mini-PBX phone systems: self contained devices and computer based phone systems. Self contained systems are easy to install and require minimal computer and networking knowledge. These pbx's provide basic features like voice mail, auto attendant, intercom and a few others. It must be stressed though that although these systems will suffice for most small business applications, they cannot always provide all the specialist features each individual business may require.
On the other hand, computer based small PBX are generally speaking for the more technically advanced users, and can offer a wider range of features that can be customised to meet a businesses requirements. A good example of advanced features is advanced IVR (auto-attendant) scripts. This allows computerised phone systems to distribute incoming calls to specific groups based on how the caller has responded to prompts. These computerised systems allow even small companies to handle their calls in a way normally associated with large call centres.
