Title: Innovator Yoshie Yamaguchi: Pioneering DTMF Transfer Technology
Introduction
Yoshie Yamaguchi is a notable inventor based in Fukushima-ken, Japan. She has made significant contributions to the field of communication technology, particularly in the area of DTMF (Dual-Tone Multi-Frequency) transmission. Her innovative approach has led to the development of a unique method that enhances communication systems.
Latest Patents
Yamaguchi holds a patent for a "Method for DTMF transfer by RTP." This method facilitates DTMF transmission between different address systems within a communication framework. The system comprises a first network (NW)A with an SIP terminalA connected to an SIP serverA, and a second network (NW)B with an SIP terminalB linked to an SIP serverB. The SIP converter plays a crucial role by detecting coded DTMF information from one of the networks during an established session. It assesses whether the other network supports the coded DTMF information and, if not, stores the corresponding voice-data DTMF into a payload of RTP for transfer to the other network's SIP terminal.
