Internet Telephony Expert in VoIP for Patent Infringement Case

Case Description:

An internet telephony system expert was needed for a patent infringement case asserting infringement over several patents for Voice over Internet Protocol, also known as VoIP. Voice over IP systems transmit telephony signals as digital audio. These are typically reduced in data rate using speech data compression techniques and encapsulated in a data packet stream over IP.

IMS ExpertServices was asked to locate an internet telephony expert who understood packet switched voice networks and the gateways between the internet and circuit switched voice networks. The expert was required to understand how VoIP differs from traditional telephone systems using the Public Switched Telephone Network (PSTN) as well as VoIP call features.
