A private branch exchange (PBX) is a telephone exchange that serves a particular business or office, as opposed to one that a common carrier or telephone company operates for many businesses or for the general public.
PBXs make connections among the internal telephones of a private organization — usually a business — and also connect them to the public switched telephone network (PSTN) via trunk lines. Because they incorporate telephones, fax machines, modems, and more, the general term "extension" is used to refer to any end point on the branch.
IP-PBX, implemented using Streamco Smartswitch can give a fast variety of complex and useful features to the enterprise, such as Call Forwarding, Call Transfer, Call Recording, IVR, etc. Additionally, due to operator functions of Streamco Smartswitch, the one can use its hunting and billing capabilities in cases when connecting to several (VoIP) providers simultaneously.
