SalesNote can record phone calls if they are made via VOIP.
E.g. Microsoft Teams Phone, or telephone exchange such as Asterix.
A conversation that runs via the "classic" telephone network can not (well) register on the smartphone itself, due to restrictions in Android / iOS.
This is possible via the Audio Capture Tool, if the call runs via the PC. Then you can easily make calls by starting the call via the PC: your phone will then forward the sound of the phone call to the PC.
SalesNote can currently be used on the smartphone for example. Put in the middle of the table during a physical conversation (i.e. with everyone in the same room), not to cap phone calls.
A softphone, digital telephone exchange, etc. can offer a solution here.
