I use my Verizon iPhone to call me home number which is on Time Warner Cable. Recently when calling home I've gotten recorded messages that "We are not available" or that call cannot be completed. My home phone seems to be otherwise working well. I get these messages only in the evening and usually when calling from restaurants. When I call my home number from my iPhone at home it connects perfectly. Any idea what's happening? I will post a similar question on the Time Warner Cable forums
