The audio file used to broadcast must be a .wav file with settings of PCM 8 KHz, 16 Bit, Mono. This format is the global standard for traditional telephone networks.
IMPORTANT: Please make sure that you do not have any silence in the beginning of your recording. The silence will likely to cause people to hang up. You can use an audio file editing tool, such as GoldWave to remove the initial silence.
Follow these instructions to check your call list against the Federal Do-Not-Call List. Please note that the instructions described here apply to both Voicent BroadcastByPhone program and Agent Dialer program.
Download your Do Not Call Lists from http://www.donotcall.gov. When downloading, please select the Text Format.
Once downloaded, use winzip program to unzip the file and save the file to a directory, such as c:\donotcall
For your call list, once it is loaded in the program, do the following:
In the main menu, select the Broadcast, and then Check Do-Not-Call List
Specify the directory that contains do not call files (for example, c:\donotcall)
