VOIP Cableing-Installation
A major development starting in 2004 has been the introduction of mass-market VoIP services over a broadband Internet connection, which allow subscribers to make and receive calls as they would over the conventional telephone network (PSTN or POTS), with similar additional features. Full-service VoIP phone companies provide inbound and outbound calling with Direct Inbound Dialing. Many offer unlimited domestic calling, and some to other countries as well, for a flat monthly fee as well as free calling between subscribers using the same provider.
