Leave the B channel rate set to 64 Kbps unless your telephone company and the locations you will be connecting to only support 56 Kbps.
TollMizer sends a data call over a voice circuit allowing you to save the typical cost difference between a voice and data call. Note that the destination you are calling must also support this feature (also referred to as Switched 56 Permissive or Data Over Voice). Check with your telephone company to ensure that they support Data Over Voice.
