David had an early love with telephones. At the age of 14, David toyed with his home telephone; re-engineered the circuit boards and successfully hooked up his Hi-Fi to the telephone set, enabling him to mimic PABX features such as music-on-hold, call recording system, and radio broadcast over the telephone line. Together with his entrepreneurial mind, David has always wanted to bridge the traditional telephone world with the hottest new network back then, the Internet. During his college days, David wrote a gateway application that converted PSTN signals to SIP, enabling him to make and receive PSTN calls over the Internet from a SIP IP phone. With overwhelming response from friends and relatives, David founded Deltapath in 2001 and developed the first generation frSIP®, a SIP based PBX, a dream he always had.
