Is it possible to fax by computer without a phone line?
Is that like a telegraph ?.
InterNACHI’s membership department uses efax, however only about 1/2 the incoming faxes get through. We explain this right on our application page: www.nachi.org/join.htm
So why are you still using efax?
Efax works fine for us and has for about 5 years. I have to admit we don’t use it all that much, but am unaware of any failures to communicate so far.
