connect an external answering machine and select to receive faxes
automatically, make sure the Rings to Answer setting is correct.
The number of rings should be higher than the number of rings your
answering machine is set to for answering a call.
answering machine picks up every call faster than the product, but
the product can detect fax tones and start receiving faxes. If you
answer the phone and hear a fax tone, check that the product has
started receiving the fax, then hang up the phone.
