The DTMF tone will be sent to the respondent's device and played through the playback sound device selected on the Audio tab.
If SJphone plays back DTMF signals too loudly, you may disable local DTMF playback by selecting the Disable local DTMF playback option on the Advanced Audio Settings panel.
Depending on the VoIP protocol and service, signals may be sent using various methods. The method is specified in the service profile.
