A computer implemented method for transmitting dual tone multi-frequency (DTMF) tones is disclosed. The method includes sending an indication to a mobile device to start a cyclic ring tone including ring and pause periods. The delay incurred to send a DTMF tone to the mobile device is estimated. The server schedules the transmission of the DTMF tone to be received at the mobile device during a pause period of the cyclic ring tone and the DTMF tone is sent as scheduled.
