Feature rich, Cost-effective Internet Telephony in a User-friendly Package.

Featuring the first Digium-developed AsteriskGUITM framework, the Asterisk Appliance 50 (AA50) integrates all the telephony needs of a small business into a single platform by effectively combining the benefits and reliability of today's high-quality voice infrastructures with access to low-cost VoIP.

The AA50 is a standalone embedded Asterisk-based PBX targeted for small to medium businesses (2-50 users), remote branch offices of larger organizations (2-50 users per site), and managed service providers for on-premise CPE-based solutions with SIP or IAX trunking. The AA50 also offers a hybrid solution alternative (a combination of VoIP applications using legacy telecom equipment) for customers who are not yet ready to migrate to a complete VoIP solution.

The AA50 is easy-to-install and feature-rich without the expense of a traditional system. The AA50 can function not only as a PBX, but also as a voice mail server, an IVR server, a conferencing server as well as a VoIP gateway. The AsteriskGUI simplifies configuration, management, and fine tuning of your AA50 system resulting in reduced su pport cost and enhanced ROI for your small business.
