Usually, the following actions are implemented in VoiceDialNumberSetup:
Place the modem into voice mode.
Set the DTMF tone-generation duration.
Make sure the speakerphone is on the hook.
Set the modem to connect immediately after dialing. However, if the modem cannot detect a busy line while in voice mode (or in speakerphone mode while in voice mode), the modem should not be set to connect immediately, so that the modem has a chance to report a busy line before it is connected.
