You do not need to have a rooted phone. Recordings are done on a secure remote server in Amazon EC2. CallerID needs to be enabled when the app dials out to the recorder. 3-way calling (or conference calling) also needs to be available on your phone. Else, you will not be able to merge the recorder call with the call you wish recorded.
App includes an mp3 previewer to listen to recordings on your phone. You can also resend the recording to the registered email address from the preview screen.
