The Asterisk Appliance (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 enterprise customers who are not yet ready to migrate to a complete VoIP solution.
