∙Poor speakerphone quality using Direct X

If you are using the soft-speakerphone version of the SM56 (that uses Windows Direct X and the PC sound system instead of dedicated voice hardware on the modem board, i.e. no speaker and microphone jacks on the modem board), and the quality is poor refer to section 10, "Improving Direct X Speakerphone Performance and Quality" for some hints and tips.

∙You cannot enter tone selections successfully when calling tone-driven applications

When dialing a remote system that requires you to enter selections using the telephone keys, such as a voice-mail depot or bank-account information provider, you can lengthen the duration of the tones your modem sends, so that the remote system can detect them better. To adjust DTMF tone length, use the AT+VTDn command, where n specifies the tone duration. Check the SM56 online Help (via the SM56 Helper application on the Windows Desktop Tray) for a list of supported AT Commands.
