Fax machine at home - with one phone line ?

[OWC Jamie]

I used to have a swirch box on the phone line that directed calls. I t worked really well until I bought this HP AIO. The switch box had to go. Never got the answering machine and fax to cooperate. No big deal at the office because the answering machine is only used during business hours when no one can answer the phone for a short bit.
