Hello everyone,

We have a Mitel sx200 el-ml that I am trying to understand better with your support (for which I am thankful).

My latest mission is an analog line that needs to be used for a credit card machine. This line works fine for the most part, but every now and then, an incoming fax tone will come in and prevent the CC machine from dialing out.

What is the most simple way for me to :

1 - find the phone # for this line & track it down in the system

2 - prevent fax noise from interrupting its dial tone (Im not sure yet if its outgoing or incoming fax)


Thanks for any tips or experience you can offer on this.
