I know this is an older link, but thought I'd give my advice for future use. If you place the call on speaker-phone then press record on the voice recorder app already on your android, you can record both sides of the conversation clearly. You can do this after dialing while waiting for the other party to answer or after you've answered when another party calls in. The call must be in process to record, so you kind of have to be quick to place it on speaker and record. If anyone texts or calls into your phone while recording the recording will stop, so you will have to press record again.
