I had FIOS installed last week and I am having a problem with call forwarding. After I forward my calls if anyone call my home # and I answer that call its fine. But if a 2nd person call my home # while I am still on the phone with the 1st call they will get a busy signal. I am forwarding my calls to my cell phone and I have been doing this for years and never had a problem. Has anyone had this problem? I tried calling customer service but the hold time is to long.
