Does anyone know if it is possible for the Asterisk server to detect DTMF tones without the other party hearing the beeps?
For example, two people are talking via the Asterisk server: one person enters some DTMP keys but the other person does not hear it. However, the Asterisk server does ‘hear’ it and it is recorded in a database.
Application: Interview between a supervisor and a potential employee. The supervisor talks to the potential employee via the phone and the Asterisk server is recording the call. The supervisor enters DTMF tones [using Analog phone behind Linksys phone adapter] (e.g., 1*) to mean different things. Those DTMF tones are logged in a database for real-time and post-programming.
Later, when the call is replayed using a Media player, the DTMF digits pressed by the supervisor are displayed. The potential employee never heard the DTMF digits pressed.
Thanks in advance for any ideas or suggestions.
