Just a suggestion. This effect can happen if you have plugged the line cord into the tel jack instead of line jack.

The busy signal that you hear when trying to send is likely from a receiver-off-hook tone.
The busy signal that someone gets when trying to fax you is due to a receiver being off-hook.
Suggest you check the following...
1. that the handset of the external telephone on the fax line is properly placed in its cradle.
2. if "hook" has been used/pressed on the fax machine, that it has been properly cancelled.
3. if there is an answering machine on the same fax line, that it is not off-hook / answering.
