Features & Capabilities

"J42 DTMF CDMA Signaling Tones" is a specialized development tool for application programmers to selectively listen to and evaluate built-in TELCO signaling tones. It facilitates developers by allowing them to hear DTMF tones as per ITU-T Q.23, Call Supervisory tones per 3GPP TS 22.001, and Proprietary tones according to 3GPP TS 31.111. The tones play through the downlink device speaker or headset without reaching the device uplink, providing a clear auditory experience as part of the AppEmbryo incubation project.
