Verify that the telephone number is entered correctly (1 for long distance, 8 or 9 for outside line access, etc.).If the phone number is correct, take out the decimal point (.) separators in the number. Some modems interpret these as pauses and cause the client software to time-out.Ensure that the line is capable of making outbound or long distance calls.Verify the correct Windows modem drivers are being used on the COM ports. The virtual COM ports must have modem drivers (usually provided by the modem manufacturer) that match the server's modems.If the dial-out still isn't working, open a case with the Tactical Software Support group at support@tacticalsoftware.com
