| 20090238194 | PSTN BYPASS FOR IP MEDIA - A system and method for falling back to a secondary network when there is insufficient quality on a primary network is disclosed. The present invention uses a PSTN as a fallback for the IP media when the IP network cannot pass the media acceptably and while continuing to use the IP network for call control and other features. In one embodiment, a call controller has a media monitoring module, a bypass module and a PSTN control module. Once a call has been established between endpoints using a primary IP network, the media monitoring module monitors for degradation in call quality. If degradation in call quality is detected, the bypass module is activated to transfer the data communication to a secondary network such as a PSTN while the call control continues to be over the primary network. The present invention also includes a variety of methods including a method for falling back to a secondary network and a method for dynamically switching between a primary and a secondary network to ensure call quality. | 09-24-2009 |
| 20100020951 | Speaker Identification and Representation For a Phone - A system and method for determining a speaker's position and a generating a display showing the position of the speaker. In one embodiment, the system comprises a first speakerphone system and a second speakerphone system communicatively coupled to send and receive data. The speakerphone system comprises a display, an input device, a microphone array, a speaker, and a position processing module. The position processing module is coupled to receive acoustic signals from the microphone array. The position processing module uses these acoustic signals to determine a position of the speaker. The position information is then sent to other speakerphone system for presentation on the display. In one embodiment, the position processing module comprises an auto-detection module, a position analysis module, a tracking module and an identity matching module for the detection of sound, the determination of position and transmission of position information over the network. The position processing module comprises a position display module and a position translation module for receiving position information from the network and generating a user interface for display. The present invention also includes a method for determining speaker position and presenting position information. | 01-28-2010 |
| 20100182921 | USER ACTIVATED BYPASS FOR IP MEDIA - A system and method for falling back to a secondary network when there is insufficient quality on a primary network is disclosed. The present invention uses a PSTN as a fallback for the IP media when the IP network cannot pass the media acceptably and while continuing to use the IP network for call control and other features. In one embodiment, a call manager has a media monitoring module, a bypass module, a PSTN control module and a GUI module. Once a call has been established between endpoints using a primary IP network, the media monitoring module monitors for degradation in call quality. If degradation in call quality is detected, the GUI module presents an interface to the user that allows selection of the secondary network or the primary IP network for continuation of the call. If the user selected the secondary network, the bypass module is activated to transfer the data communication to a secondary network such as a PSTN while the call control continues to be over the primary network. The present invention also includes a variety of methods including a method for falling back to a secondary network and a method for dynamically switching between a primary and a secondary network to ensure call quality. | 07-22-2010 |
| 20100266111 | Phone URL Exchange - A computer system (a method) for exchanging information such as a Universal Resource Locator (URL) or a Universal Resource Identifier (URI) over a communication channel in general and over a telephone communications channel in particular in a unified communications system is disclosed. In one embodiment, the system comprises a phone URL exchange unit configured to receive a phone URL exchange request from a first endpoint, to determine the URL to be sent and URL encoding method based on the request, to encode the URL into audio data or as a part of the communications control signals using the URL encoding method and to send the encoded data to a second endpoint over the telephone communications channel. The phone URL exchange unit is further configured to receive audio data or the communications control signals embedded with a URL and to decode the received data to reveal the URL. | 10-21-2010 |
| 20110096762 | CLOUD VOIP SYSTEM WITH BYPASS FOR IP MEDIA - The cloud computing VoIP system includes a software as a service (SaaS) site and one or more additional sites. The SaaS site includes a gateway and a call manager and is coupled for communication across an IP network and the PSTN. The call manager includes a media monitoring module, a bypass module, a PSTN control module and a GUI module. The SaaS site handles and controls voice and video calls over the IP network and the PSTN for endpoints at the one or more additional sites. In another embodiment, the cloud computing VoIP system is also coupled to a cellular network and the endpoints include an associated cellular phone. The cloud computing VoIP system also includes a method for falling back to a secondary network, namely the cellular network, when there is insufficient quality on a primary network. | 04-28-2011 |
| 20110211496 | PHONE-INDEPENDENT KEY EXPANSION MODULE - A button box provides additional keys that can be used in conjunction with a telephone. In one embodiment, a button box is configured by associating it with a telephone and by programming its keys. When a key on the button box is activated, a key press event is sent from the button box to the associated phone. The phone treats the key press event as if a key on the phone itself had been activated and forwards the event to the voice switch appliance associated with the phone. (Alternatively, the key press event is sent from the button box directly to a voice switch appliance.) The button box's user interface is controlled by a voice switch appliance. | 09-01-2011 |
| 20110281580 | MOBILE PHONE INTEGRATION WITH A PRIVATE BRANCH EXCHANGE IN A DISTRIBUTED TELEPHONY SYSTEM - A system and method for providing PBX functionality to a mobile phone includes a private branch exchange having a mobile phone proxy. A call control path is established between the mobile phone and a private branch exchange. The call control path is a direct trunk line, a mobile voice network, an IP data network, a mobile data network or a 4G network. The private branch exchange receives a request to perform the PBX function. The private branch exchange uses the call control path to perform the PBX function. | 11-17-2011 |
