Avance Business Technology can implement and manage for your business a state of the art IP phone system. IP telephony is simply a phone system that uses an “IP” network (the same as your computers), rather than a traditional copper line. This is also known as VoIP (Voice over IP) and is commonplace in many homes and businesses. A business grade VoIP solution however, is vastly different to that of a home one, adding many more features such as a PBX (Private Branch Exchange) system and superior QoS (Quality of Service). Our service relies on the open source global standard of SIP, meaning no more vendor lock in! - You can migrate your hardware to any of hundreds of other providers, future proofing your investment.
