I have only 1 phone line for this machine plus several phones connected serially. Are there any settings to allow me to: 1. When there is a call, after a specified no. of rings the MFC-7340 will cut in. Meanwhile all phones stop ringing. If it is a voice call, MFC-7340 will disconnect but the other phones will resume ringing. 2. If call comes in and I pick it up from a regular phone to find out it is a fax. I hang up and the MFC-7340 will pick it up later to receive the fax.
