I had an old mobile, used the record app and used mine on loudspeaker. Microphone next to the speaker on the mobile I used.
I informed them first that I was recording.Very important.
Do the same when I call someone and they say that the call might be recorded for training purposes.As soon as they answer, states that I am recording as well.
Paid of a few times as sometimes the promises in the initial sales pitch is not kept.
There are ways to use any voice recorder with an purchased isolation transformer on your landline if used.
In emergency a couple cap's can be used or a coil, albeit not legally.
