I have an incoming fax number on my sonic account, 707-823-xxxx, set to forward to my sonic email. I rarely use it. Someone tried to send me a fax to that number this morning but it wouldn't go through (she said her fax machine said "no answer"). I tested the fax line by sending a fax to that number from a neighbor's fax machine and had the same problem, no answer. Customer support said they do not support lab services, but recommended posting to this forum. Any suggestions?
