In its simplest format, receiving a fax only requires that you route an incoming call to an extension, which then executes the
rxfax dialplan application. As with the previous recipe, we can use our FreeSWITCH server to be both the sender and the receiver of the fax. For our test, we will use the same file we used in the Sending faxes recipe
Execute these steps to carry out a simple fax transmission and reception:
Execute this command:
originate loopback/9178 &txfax(/tmp/txfax-sample.tiff)
Watch the console. Eventually, the fax transmission should be successfully completed.
