BELCOM-ISDN "PLUS" PABX system, thanks to its intelligent hybrid-cellular chip technology, allows creating a link through a real network (Q SIG, BELCOM SIG and NetVDoIP) or a virtual network (ISDN) of short, average and long distance. This characteristic is very useful for companies or institutions that have services in different locations.

The network can have, or not, centralization of telephonist and financial management functions. If the BELCOM SIG or NetVDoIP digital protocols are used, the system provides total transparency of functions as if it was a single PABX system in the same building.

There exists a single Numbering Plan in the company and any extension has the same operation mode. This functionality provides an increase of operability and union in the whole company.

The NetVDoIP advanced Technology allows to build an intelligent and integrated network of voice, data, fax and image on IP (video, VoIP, FoIP and data). The system also supports the xDSL protocol.
