Fax machines may work, or may not. VoIP and fax often work fine, but sometimes they do not. Same goes for alarm systems. You may choose to retain a copper landline for these if they do not work for you on the VoIP service.
When a call is in session, the VoIP connection uses less than 50kbps.
Just wanted to add a data point. My Brother IntelliFAX 2820 always worked fine for sending faxes out on the ADSL copper line Fusion service. After switching to FTTN (with vastly improved speed by the way) the faxing no longer works in automatic mode. It would dial out, the other side would pick up, a lot of "squeaking" but no communication established, then time out. However I did find a workaround:
Use
off-hook or manual mode on the fax machine, i.e. dial the number from the fax machine as if wanting to make a phone call with the fax machine. Once the other side picks up, then add the fax page to the feeder and press the start button. Somehow the line quality when starting as a voice call is better to make the communication work.
The setup is:
ATT Uverse gateway [Pace model 5031NV-030] directly to Sonic supplied SIP to analog converter box [Grandstream HT701] and from that box with phone cable directly into the fax machine [Brother IntelliFax 2820].
Maybe this can help others trying to send a fax over VoIP / SIP line. It's worth a try.
