History 
AireSpring was founded in 2001 by Avi, Daniel, and David Lonstein who in 1997 sold ADDTEL Communications, Inc., their privately held company resold switched long distance, to SA Communications, Inc. The Lonstein brothers reinvested a portion of their returns into a new company whose sole focus was on the small to medium-sized business and multi-location enterprise market and called it AireSpring. The company began where it left off, selling switched long-distance services. Since then, AireSpring has expanded its portfolio to include local phone service, dedicated internet, ethernet, MPLS VPN, SD-WAN, Cloud Connectivity, Managed Security (firewalls, DDoS mitigation) and VoIP/SIP trunking services. In 2014, AireSpring acquired hosted contact center provider, simplyCT. Network
