Digium, the Asterisk Company, has released a new version of Switchvox, a Voice over IP (VoIP) Unified Communications (UC) offering designed for small- to mid-sized businesses.

Based on Digium’s Asterisk, a open source telephony engine Switchvox SMB is an IP PBX that integrates a web interface with UC features such as fax, chat and video calling, the company said.

Digium said that the introduction of Switchvox 4.5 and new Phone Feature Packs extend the Switchvox to Polycom phone handsets for control of the communications system.

Accordin to Digium, new features that are available through Phone Feature Packs enable users to access features from the phone handsets such as call recording, visual voicemail, a searchable company directory and call parking lots. New options for fundamental phone functions, such as hands free click-to-call dialing, distinctive ringtones for different types of calls, extension failover to a backup Switchvox SMB server, and support for multiple extensions on a single handset, are also included.

In addition, the new version also offers features to support users including, caller profile information that appears on the Switchboard and on the display of Polycom phones with Phone Feature Packs on internal calls; availability of manual and online help in English, UK English, Italian, Castilian Spanish and Latin American Spanish; and implementation of simple network management protocol.

Tristan Barnum, director of Switchvox product marketing at Digium, said: “Switchvox SMB’s tight integration with web applications and back-office software gives businesses an unprecedented level of productivity, while features like VoIP, chat and video calls provide flexibility and profound cost savings. Today, with the introduction of version 4.5, we’re extending the most popular functionality of Switchvox to the feature rich Polycom handsets, where they can be accessed intuitively.”
