This. A detailed description of the call - what was discussed, who was discussed, what I said - reconciled with a record from the phone or phone company is more than enough. This is what many other professions, including medical, do. If you're involved in a multi-million dollar lawsuit, sure you'll nitpick with lawyers about the content of the call, but for a few grand, no one's going to argue with you. There's also too many headaches with recording calls. Dealing with one party vs. two party states, etc.
