Summary of the Invention
[0005] The present invention generally provides a method for recording a wireless phone call and wireless phone recording system for recording audio from wireless phone calls. The wireless phone recording system can have an interface that is seamless and undetectable by the user so that the system can be used for covert applications, such as for use by undercover law enforcement personnel, or the system can be used as a business security tool installed on all wireless phones issued by an organization.
[0006] The wireless phone recording system can include a call-recording application. The call-recording application on a wireless phone can be configured to run at all times, so that all communication on the wireless phone can be recorded. Alternatively, the call-recording application can be used as an on-demand application so that a user can start and stop an audio recording as necessary.
[0007] In the method of the present invention, an external call is established with the wireless phone. The call recording application establishes an independent, internal call using loopback or similar application, and conferences the internal call to the external call. This conference may be made via the phone's API, or simply by nature that both calls are using the same microphone and speaker devices on the phone for the audio interface to the user. Audio of the internal call can be captured and stored at the wireless phone by various methods, including, but not limited to, capture of the packets transmitted between endpoints of the internal call, or via audio output software interface on either of the endpoint applications involved in creating the internal call Thereafter, the audio can be forwarded to a third party database for storage. The call-recording application can produce an audio file that can be used for litigation purposes, conversation verification, and many other purposes to avoid a hearsay situation. The call- recording application can also be used in organizations where they can be required to record all calls in order to comply with legal or regulatory statue. [0008] The invention will be more fully described by reference to the following drawings.
