To allow interviewers to use modems to dial phone numbers, select Modem – Show Dial Contact button on the Interviewer screen from the Dialing Options list. The Dial Contact button on the main screen of the Phone Participants activity will then be usable. When interviewers click that button, the phone number displayed in the main screen will be dialed automatically by the modem. The modem option works only for phone numbers that are formatted as follows:

For example, 44 12 3456 7890 for a subscriber in the United Kingdom. In addition, a separate software installation is required on each telephone interviewer station that will use the modem option. For more information, search the UNICOM Intelligence Interviewer - Server Admin Installation Instructions for the ‘Things You Must Do on Local Computers’. If a station has access to more than one modem, you can specify which one to use; for more information, see Settings for the Phone Participants activity.

If you select the option to use modems, the project cannot use an autodialer. Interviewers can still dial numbers manually if they have access to a telephone keypad. The modem option works only in Microsoft Internet Explorer on Microsoft Windows.
