The story
Soon after its establishment, Dialexia released Dial-Office IP-PBX, an IP PBX platform designed as an alternative to the circuit-switched telephone network. PBX is a system that connects telephone extensions of a company to outside public telephone network as well as to mobile networks. On May 21, 2014, Dial-Office was named runner-up in the IP-PBX Servers category of WindowsNetworking.com 2013-14 Readers' Choice Awards.
In 2003, Dialexia released Dial-Gate Softswitch PBX, a web-based softswitch and billing server based on the Session Initiation Protocol. A softswitch, short for software switch, is a central device in a telecommunications network which connects telephone calls from one phone line to another, across a telecommunication network or the public Internet, entirely by means of software running on a general-purpose computer system.
In 2008, the company released HERO Hosted PBX, a hosted PBX platform made for operators and large corporations wanting to host IP PBX services on office grounds.
