Pingtel combines the best attributes of open source development - low cost, adaptability and flexibility - with the reliable solutions and support enterprises require for voice applications. Pingtel’s open source SIP PBX is the linchpin technology that will catalyze the movement of enterprise communications into the data center and away from purpose-built hardware. Like enterprise-grade Linux, this approach will drive commoditization of traditional telephony hardware and software and eliminate vendor lock-ins that keep prices high and limit innovation.
