Voice software firm wins $4.5 million

Trinity Convergence has raised $4.5 million in a second round of funding that included investments from Core Capital Partners, Intersouth Partners and Mid-Atlantic Venture Funds. The Raleigh, N.C.-based company develops software that enables the transmission of voice conversations over data networks. The company's VeriCall product is designed to help telecommunications equipment makers build Internet-based voice networks. Including the round announced this week, Trinity Convergence has raised $7.7 million.

Net-based phone calls are a potentially cheaper alternative to making calls through traditional phone carriers, such as AT&T, Sprint or SBC Communications.
