I have a new HP Photpsmart all-in-one with FAX. Everyone from ATT to HP say I can not FAX with VOIP? Can someone help me through any work around? I have the ATT phone cable from wall which plugs in to gateway - 2 slots used, 1. Phone Line and 2. Lines 1 and 2. I have read everything from splitters to baud rate etc. I am confused an would appreciate any assistance. Thank you
