SMSi specializes in Asterisk system design and maintenance, and have been implementing and maintaining Asterisk VoIP systems since 2007. We provide full engineering consulting, installation, configuration, custom dial-plan configuration, training, and post-support for Asterisk customers either with or without support contracts.

Asterisk is an open-source PBX solution perfect for businesses needing a custom solution to handle customers in a way no other commercial PBX products can. Asterisk typically runs on a Linux platform, and is extremely versatile. It is easily expandable and supports analog lines, VoIP trunk lines, and digital PRI circuits.

A custom Asterisk configuration allows support for any number of analog or IP phones. It can interoperate with almost all standards-based telephony equipment using relatively inexpensive hardware. Its features include voicemail, callerID, auto attendant, dial-by-name directories, call conferencing, music on hold, interactive voice response (IVR), call queuing, three-way calling, protocol bridging, flexible extention logic, and much more..

Asterisk is the de facto standard in modern VoIP PBX systems.
