Our PBX makes it possible to proceed incoming call transfer to any numbers, including mobile and home phones. Such parameters as time, week day (working day or weekend), identifier of a caller and others are taken into account. Scenario of a call can be chosen in the special section. The quantity and difficulty of scenarios are not limited.

PBX and IPPBX
A private branch exchange (PBX) is an internal telephone exchange or switching system used within a single office or organisation. The chief benefits of a PBX are cost and convenience. Using an internal system allows employees to communicate directly without requiring the use and expense of external telephone lines. Outgoing calls by a large number of employees may be shared on just a few lines. Meanwhile, additional services can be integrated with the switching system, such as routing calls to intercoms and other destinations.
Some form of PBX is now the norm for businesses, particularly in large organisations, where it is unnecessary and inefficient to rent many external lines. Internet protocol PBX (IPPBX) systems adopt the same approach as the older traditional PBX, with the difference that they use computers and existing internet infrastructure to route calls within an organisation. This allows for greater efficiencies and versatility, since digital facilities can be integrated with the telephone system – including message storage and connection to voice-over-IP (VoIP) services – while still using a limited number of lines to interface with the external telephone network. Since almost every business is connected to the internet and uses high-speed broadband infrastructure, IPPBX offers substantial advantages at a low cost overhead when compared to legacy telecommunications systems.
EncryptoTel will offer a virtual IPPBX, as well as easy integration of encrypted VoIP into existing IPPBX networks.
