Is it possible to have 2 different phone #'s ring the same phone? I am finding myself, with No use for a landline for my business! I only use the fax machine 2 times a year.. (maybe).. But, All of my yellow book advertising, has my land line listed! And that one is forwarded to my cell phone 24/7.. I dont wanna give up either #, as they are both important to me, and my business? Is there a way??
