Phone Systems

Our primary and preferred phone system of choice is an Asterisk based system.  These systems allow us to customize a PBX tailored for each specific customer and their needs.  Each system is thoroughly planned out based on a Q&A session with our customers to better understand what the REAL and WANTS are for the new phone system.

Asterisk-based telephony solutions offer a rich and flexible feature set. Asterisk offers both classical PBX functionality and advanced features, and interoperates with traditional standards-based telephony systems and Voice over IP systems. Asterisk offers the advanced features that are often associated with large, high end (and high cost) proprietary PBXs.  We have detailed some of the KEY features below in each category.  however the features on this platform are virtually limitless!
