Iaxy Fax and Poor line quality


#1

I’ve got an iaxy 2 set up with a fax machine. It dials, answers etc, but the fax part is not working.

The machine is saying “Poor line quality” Is there anything I can do for this?

For the extension if got it set to:

allow: ulaw
disallow: all

Help!

How much bandwidth do you have? That might be an issue. You can also try setting up jitter.

You can also try to set up tos

that may help you out.
