Are you using a phone company’s voice messaging service?
This is a voice messaging service used to replace telephone answering devices. If the messaging
service’s rings-to-answer setting is lower than the product’s rings-to-answer setting, the
messaging service answers the call and the product is not able to receive faxes. If the product’s
rings-to-answer setting is lower than that of the messaging service, the product will answer all calls
and no call will ever be routed to the messaging service. The only voice messaging solution that
can be successfully used with the product is a stand-alone telephone answering machine.
