I have a Canon MX922 that will not send fax when answering machine says dial *9

[tri2sli]

I have a Canon MX922. I use Ooma with a dedicated # for faxing. I have sent faxes and received faxes but will not send fax to home #s that do not have dedicated fax #. After dialing the persons home phone #, their answering machine picks up and says dial *9 to send fax which I do. I get a fax error report that the line is busy. I have talked to them on cell phones while doing this so I know they are not on their phone or picking up while fax is transmitting. What can I do to correct this problem?

Hi tri2sli,

Disabling the error correction mode (ECM) and reducing the transmission speed of the fax may resolve the issue.  To do this, please follow the steps located at the links below:

PIXMA MX922 Enable / Disable ECM TX Mode

PIXMA MX922  Reducing Fax TX (Transmission) Speed

Hope this helps!
