If your computer has a traditional data/fax modem (internal or external) connected to your phone landline, Dialectic can dial the phone by generating touchtone signals through the modem. You dial through the modem, but you talk through your phone. Once you dial, you will be instructed to pick up your receiver to conduct your call. If you do not pick up the receiver then when the modem hang up time has expired, the call will be disconnected.

Modem Dial Method Category. The group of all Modem Dial Method configurations.
Modem Dial Method Configurations. Configurations allow you to customize the Modem Dial Method using different modems or settings for different types of calls or locales.
Modem. The modem to use for dialing.
Init String. The initialization string for the chosen modem (you can use one of the supplied init strings, use your own, or even try using Dialectic with no init string at all — leave this field blank).
Monitor Sound Through Speakers. If enabled, the modem’s tones will be played through the speakers when dialing.
Wait for Dial Tone. If enabled, Dialectic will wait until there is a dial tone detected on the line connected to the modem. If you are using your modem with a VoIP service that provides an analog telephone adapter (ATA) that does not supply a standard dial tone, you should disable this option. Also, to make dialing with the modem quicker, disable this option.
Tone or Pulse. For nearly all setups, tone is the option to use.
Disable Calling Tones. The Disable Calling Tones checkbox is useful only under non-US phone systems, to prevent the modem from emitting the extra beeps that tell the phone system that the call is data. The call is not data: you’re dialing with the modem, but the call will be a voice call (not, say, a fax). Thus you may need to check this checkbox for certain non-US phone systems. Do not check this checkbox in the US, because on the US phone system the checkbox works backwards: checking it will turn the extra beeps on!
Wait for a Response. Enable this if you want Dialectic to wait for a response (e.g., a busy signal) before continuing. Dialing with this option enabled can add a few seconds to the dialing and make the application unresponsive when dialing. For this reason, some users prefer to disable this option. However, disabling this will also disable the automatic redial on busy feature.
Redial on Busy. When “Wait for a Response” is enabled, you can use this feature to automatically redial the last number when a busy signal is detected. Set the delay between attempts and the total number of attempts to try before giving up. If a redial attempt is successful, no further attempts to redial this call will be made.
Hang Up Delay. The seconds to wait before then modem hangs up. You must pick up a connected extension before this time has expired or the call will be disconnected.
