Devices, software and methods for passing DTMF signals under voice compression

   
   

Devices, software and methods are provided for encoding DTMF signals for telephone connections between digital voice communication systems that use compression, such as wireless connections or network connections. First the twist of the DTMF signals is determined, and then it is determined whether the twist is within a mapped range of a remote decoder. If not, the signal is first balanced to change the twist, and then the balanced signal is encoded.

Los dispositivos, el software y los métodos se proporcionan para codificar las señales de DTMF para las conexiones de teléfono entre los sistemas de comunicación digitales de voz que utilizan la compresión, tal como conexiones sin hilos o conexiones de red. Primero la torcedura de las señales de DTMF se determina, y entonces se determina si la torcedura está dentro de una gama traz de un decodificador alejado. Si no, la señal primero se balancea de cambiar la torcedura, y entonces la señal equilibrada se codifica.
