[hylafax-users] noisy fax calls?

[mnoel@xxxxxxxxxxx]

I am seeing an issue similar to what Paul described concerning extra noise on the fax line.  For us it is intermittent but we are seeing a large number of incoming fax calls get disconnected prematurely.  I've pasted a typical log file below. 

 

The called number isn't reported here.  I'm not sure why.  Usually it is in these logs files.  Also, it looks like the first bit of data is repeated a couple times and then things start to timeout.  Eventually the connection drops. 

 

I don't know how to read the data stream that is presented here in the log file so I don't know if there is any useful data here.  Can anyone tell what the error might be?
