Lab test: VoIP phone systems walk the talk
Appliances from Allworx, Critical Links, Fonality, Microsoft, and Sutus have slick telephony features and affordable price tags, but differ significantly in breadth, depth, and complexity
Critical Links EdgeBox Office v.4.5.2
Score: Good 7.9
Bottom Line: This all-one-one appliance integrates Asterisk telephony, networking, e-mail, file sharing, and Web server into a single enterprise-grade solution. However, the many moving parts and interfaces add complexity to configuration and use. Phone services include interactive voice response and conferences as well as queues and other features for call centers. QoS management lets administrators set VoIP and Web caching policies.

Fonality PBXtra 4.0
Score: Excellent 8.8
Bottom Line: PBXtra is a scalable phone system with a user-friendly interface, making it easy to install, use, and maintain. A "hybrid hosted" architecture lets Fonality remotely manage the system. The basic configuration is value-laden, with strong Outlook integration, conference bridges, and CRM hooks; plus it supports analog and VoIP phones. The Professional edition adds multiple auto-attendants and conferencing, while Call Center tacks on unlimited call queues and agent capabilities. See complete review.
Microsoft Response Point 1.0
Score: Very Good 8.3
Bottom Line: Response Point combines software from Microsoft and hardware from IP telephony vendors. Reliable voice recognition -- without any training -- is unique among the products tested, and helps make the system remarkably easy to use. Setup and admin are a snap, and it's easy to add new users and phones -- up to 50 without additional licensing fees. Telephony features are basic. If basic meets your needs, this system is a perfect fit for the small, Windows-centric office. See complete review.
Sutus Business Central SB-200
Score: Very Good 8.4
Bottom Line: Sutus' unified communication solution combines telephony, e-mail and file servers, and even wired and wireless networking in a single box. This reduces hardware costs for offices of up to 25 users, while easing administration. The system integrates VoIP and PSTN lines, via an included gateway, while phone services convert voice mail to e-mail. Sutus lacks the advanced telephony features and expandability of some competitors, but its wizard-driven setup, reliability features, and collaboration spaces should be a hit with smaller offices.
