I have a newb question. We have an 1861 deployed at one of our remote sites. There are 5 total IP phones and 4 analog lines connected into the FXO ports on the 1861. The 1861 is connected to a 3Meg DSL connection that runs over the same line as the fax line. When a customer calls in, there is really bad echoing and sometimes you can't understand them at all. This goes for local and long distance. What I have noticed is when there is data moving across the pipe, call quality goes way down. We did a few tests where we would call them and then copy a 10MB file to a computer located at their facility. The call quality was terrible during the copy process but got better once the copy was done. I don't understand how copying a 10MB file to a computer would affect a call coming in on an analog line. Can anyone help me with this?
