How vPBX works ?


Traditional PBX solutions are using a proprietary system ( i.e. rack with telephony cards or a server with telephony cards) located at customer premises.


vPBX service is not using any system at customer premises, so the customer doesn't need to utilize any special location (data room). Only telephone sets are used. The connectivity to Rolaware’s systems, placed at MED Nautilus Data Center in Athens, is secured via a router (or a layer 3 switch) located at customer premises, utilizing, the leased line offered by Rolaware Hellas for the service. Call signaling along with incoming and outgoing calls towards the company premises are traversed through this leased line.


vPBX is utilizing a variety of telephone sets using VoIP and SIP signaling. A catalogue of these sets is available. In those cases where analog sets are used Analog Telephone Adapters (ATAs) are in use, though the functions enjoyed by the users are substantially less. In each extension location an Ethernet port is used. VoIP sets are offered with 2nd Ethernet port where the employee PC can be connected. Each set can be configured separately, according to customer needs. In general the incoming and outgoing call flow can be designed and configured according customer needs and the features offered by the service.


vPBX is tailored according customer needs. Usage and costing are based upon activated telephone extensions, so it follows the versatility of the numbers of employees in the company.
