SUMMARY OF THE INVENTION

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.

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.

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.

The invention will be more fully described by reference to the following drawings.

The call-recording application can include an interface for the user or can be undetectable to the user. In block 16, an external call to another phone can be initiated or received by the wireless phone including the call-recording application. In block 18, the call-recording application can establish a connection via a loopback or other similar connection internal to the wireless phone to set up an independent internal call to the wireless phone. Accordingly, the call-recording application allows the wireless phone to communicate with itself without external network connectivity. In block 20, the call-recording application can conference the external call with the internal call 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. In block 22, the call-recording application can capture an audio stream via either application endpoint which are conferenced to the internal call or audio packets from the internal call, or a similar method for capturing audio data. The audio data can be compressed into a waveform or similar digital audio file in audio format. In block 24, the call-recording application can compress the audio or audio packets and can then write the compressed data to local storage on the wireless phone. In block 26 the external call can end and the ending of the external call can trigger the internal call to end.

With reference to FIG. 2, flowchart 10 can proceed from A. In block 28, call data, such as, for example, call direction inbound or outbound, date, time, caller number, duration, dialed number, GPS location, SMS messages, MMS messages or any other data present on the mobile phone or additional attributes about the phone and/or call can be saved in the local storage on the wireless phone and can be associated with the one or more files captured for the audio stream or audio packets from the internal call. In block 30, a digital watermark, fingerprint, or encryption can be associated with the one or more files captured for the audio stream from the application endpoints which are conferenced to the internal call or audio packets from the internal call. In block 32, it is determined from the interface if the end user chooses to record the call, if the end user does not choose to record the call, the one or more files for the captured audio stream or audio packets from the internal call can be automatically deleted. In block 34, the one or more files for the captured audio stream or audio packets from the internal call can be securely streamed or transferred to one or more third-party recorder databases via any wireless data connection available on the wireless phone, such as, for example, cellular data, Bluetooth, wireless local area network, or other connections. In block 36, the one or more audio and data files can be deleted from local storage of the wireless phone once it is verified that the transfer was received by the one or more third-party recorder databases. Alternatively, the one or more audio and data files can be retained in the local storage of the wireless phone for catalog and playback.
