Unison Extends Free UC to Cisco, Digium Gateways

Unison Technologies Inc. announced its Unison Server now supports SIP gateways from Cisco Systems Inc. and Digium Inc., allowing small and medium businesses to deploy Unison’s free unified communications software using traditional phone lines.

Cisco and Digium gateways connect analog telephone lines to an IP PBX, enabling businesses to keep their existing infrastructure. By connecting the gateways to the free version of Unison’s UC software, they can offer click-to-call, voice-mail-to-e-mail and real-time call recording features without buying an IP PBX or IP telephones.

“Extending Unison to analog telephones as well as IP telephones will further broaden the appeal of our free unified communications platform,” said Igor Balk, CTO of Unison Technologies in a press statement. “For the relatively low cost of a Cisco or Digium hardware gateway, any small or midsized business can now keep their existing analog lines, while at the same time upgrading to Unison unified communications. It is a great way to move beyond legacy systems such as a proprietary, standalone PBX.”

Unison integrates a full-featured IP PBX as well as e-mail, instant messaging and real-time presence in a single Linux server and single Windows or Linux desktop client, creating replacements for both PBX systems and legacy e-mail servers like Microsoft Exchange or Lotus Domino.

A sponsor-supported edition of Unison is now available free and can be downloaded at No license is required. The standard version without ads costs $50 per user per year.
