Fonality said Monday it has released trixbox Pro, a free business-grade phone system that allows companies with five to 500 employees to make free VoIP calls.
In addition to traditional PSTN dialing and PBX features, trixbox Pro also includes conference calling, unified messaging between voice mail and e-mail, employee presence management, embedded corporate chat server and the ability to integrate with Microsoft Outlook, Salesforce.com and SugarCRM.
trixbox Pro includes trixNet, an in-network calling service that lets users call any other trixbox Pro user. Calls over trixNet are not subject to any local or long-distance charges.
Fonality said it also is planning to extend trixNet to the trixbox Community Edition platform, its open source Asterisk-based software that has been downloaded more than 1.4 million times. The company said it will extend free trixNet calling to include anybody using GoogleTalk in 2008.
trixbox Pro is a hybrid-hosted phone system, which means the free software is first downloaded by a business and installed on a local computer and local IP phones. The local computer connects to the Fonality network. The trixbox Pro also extends the phone system outside the corporate firewall, so an employees extension can be used at home, remotely on a laptop or on a mobile phone.
