Fax can't connect with other fax machines
We have 2 dedicated lines that we use just for each of 2 fax machines. One fax machine works just fine on it's phone line, the other one started not to work a while back. We just bought a new fax machine thinking that was the problem but we're still having trouble. We have a dial tone and can call in and out. We can receive fax's (although it's very slow) but can not send. When we try to send, it dials out, the other machine answers the call but can not recognize the machine on the other end. I called the fax machine company and they said that they can not guarantee that a fax machine will work on a VOIP phone line due to the traffic problems associated with them and that I should call the phone service provider. Is there any help you can give me? By the way, the fax used to work just fine but something must have chaged because it stopped a while back.
