Recording Room & Telephone Conversation

There are occasions when it's sensible or even essential to covertly record conversation for evidential purposes. This may be a discussion that you're having, or perhaps a third party conversation between other people that you need to know about.

The choice of equipment will depend on circumstances and whatever feels comfortable for you.
