Necesito ayuda con la configuración de mi Asterisk, ya que no soy capaz de recibir el DTMF, con la opción que selecciona el usuario, tras escuchar la locución de la IVR. He intentado transcodificar la señal, y aplicar diferentes configuraciones, y codecs sin éxito.

...podamos seleccionar para los teléfonos que nos interesen a la hora de añadirlo al portal. Cuando Asterisk reciba una llamada, mire si nº de teléfono que recibe esta en la lista de los marcados con el tick de "Control". En caso que no, haga lo que hace ahora (cuelgue la llamada y lo anote en el portal, la hora que ha recibido la llamada) En caso que si, descuelgue la llamada, identifique la trama de DTMF que le envía el teléfono y cuelgue la llamada. Si dentro de esa trama identifica el tono D, muestre en una casilla "Error control", en caso que no, realice el proceso de siempre, identifique la llamada y muestre en la casilla correspondiente la hora de la llamada. Tengo contacto con el desarrollador que nos hizo la part...

El proyecto consite en crear un PBX en Asterisk, que nos permita la gestión remota mediante un protocolo basado en peticiones a un API Rest con formato JSON, para poder controlar el flujo de la llamada. Las acciones que permitirá cuando el sistema recibe una llamada son: Reproducir una lista de locuciones. Reproducir una lista de locuciones y poder capturar DTMF Poder transferir la llamada (añadiendo y modificando algunas cabeceras SIP) Poder liberar la llamada (añadiendo y modificando algunas cabeceras SIP) Grabar una llamada. Grabar un mensaje Revisa la documentación adjunta, para ver el protocolo en detalle

Create an DTMF decoder algorithm. The Android APP should uses the algorithm to decode any DTMF tone on the audio signal received by the microphone. The final delivery should be a Android APP that: - Listen the microphone sound, searching for a DTMF tone. - Decode the received DTMF tone. - If there is a DTMF tone on the audio input then the app should display the decoded DTMF numbers. - The software should filter the input microphone audio (digital band pass filter) to avoid noise or contaminations. NOTES: - The DTMF decoder algorithm should allow tone frequency value modification - There is an example on Github "pjasiun/ dtmf-decoder"
