CID reporting using DTMP or Touch-tone was developed by which organization?

Explanation:
CID reporting using DTMF or touch-tone refers to sending alarm events over a telephone line by transmitting digits encoded as tones. Motorola developed this DTMF-based reporting method, and it quickly became the standard approach used by many central stations because it allows alarm data to be sent in a machine-readable, consistent format. This made it easier for central stations to decode events and apply the correct response codes. While other manufacturers produced compatible equipment, Motorola’s development of this DTMF CID reporting laid the foundation for how many systems communicate alarm events over telephone lines.
