摘要:
An H.323 client terminal (102) according to an embodiment of the invention employs primary and secondary H.323 control units or state machines (110a, 110b). The primary control unit (110a) sends signaling messages to a primary gatekeeper (108a) and triggers the secondary control unit (110b) to send a message with an appropriate correlation identifier to a secondary gatekeeper (108b). The primary control unit (110a) establishes a call per standard H.323 protocols. The secondary control unit (110b) also establishes a call via a secondary gatekeeper (108b). However, no media channels are established for this back up call. As the secondary control unit (110b) receives signaling from the secondary gatekeeper (108b), it checks the status of the call with the primary control unit (110a). If the call signaling on the primary control unit (110a) is proceeding normally, no further action is taken. If the call signaling with the primary gatekeeper (108a) fails, the secondary control unit (110b) takes over communication.

摘要:
A system, method, apparatus, means, and computer program code for determining a location of a device (130) connected to a network (202). According to some embodiments of the present invention, a device (130), such as an IP enabled or compliant telephone, may receive, detect, or otherwise actively or passively determine a location identifier. The location identifier may be associated with a geographic location of the device (130). The device (130) may then provide data indicative of the location identifier to another device (204), such as a network manager device, server, computer, etc. In some embodiments, the device (130) may determine its geographic location after receiving a request for data indicative of its geographic location. In other embodiments, the device (130) may provide data indicative of its geographic location each time it receives, detects or otherwise determines its geographic location. Alternatively, the device (130) may provide data indicative of its geographic location only upon request or when it detects, receives or otherwise determines a new location identifier.

Embodiments of the present invention provide a system, method, apparatus, means, and computer program code that facilitate or allow use of instant messages as notifications. In some embodiments, a notification is created by an application (152) to be sent or included in an instant message sent to a user. In other embodiments, middleware or other software (154) may intercept or detect a notification (e.g., dialogue boxes, pop-up windows) generated or initiated by an application (152) and create and send an instant message to a user based on the notification
摘要:
A system (100) that employs media "blending" to notify a multi-media user of the use of one or more default configurations and provides an opportunity to record or reconfigure the item for the future. In particular, a system (100) according to the present invention monitors usage of a default or other predetermined setting and provides a message to the user indicative of its usage. Once the user has been notified of the usage, the user is given the option of reconfiguring from the default setting.
摘要:
Methods, apparatus and computer system for efficiently utilizing a conference bridge capacity in order to support a multipoint conference call are described. Each conference bridge 212 within multiple communication groups 202a-n determines which local communication unit 206-210 is a dominant local communication unit, quantizes that dominant local communication unit's signal, and transmits the quantized signal of the dominant local communication unit via signalling channels to the other conference bridges. Each conference bridge 212 then compares the various quantized signals of the various dominant local communication units to determine an overall dominant communication unit of the multipoint conference. Then the signal of the overall dominant communication unit is then transmitted to all communication units 206-210 participating in the conference call in various ways for different embodiments of the invention.
摘要:
An improved voicemail system (101) that allows a message waiting indicator to be forwarded to a remote location is disclosed. The voicemail system (101) includes a voice mail controller (103), a home location (105), and a remote location (109). A user of the voicemail system (101) is assigned a home location (105) for the reception of calls and deposition of voice messages. The user can configure the voice mail controller (103) to forward a message waiting indicator to the remote location (107) when a message is left. The voice mail controller (103) stores a table (401) that indicates the location to which a message waiting indicator should be forwarded to for each user of the voicemail system (101).
摘要:
An electronic messaging scheme is described that is configurable to prevent intentional and unintentional transmission of electronic messages subject to one or more access restriction conditions. In accordance with one aspect of this electronic messaging scheme, an electronic message is interrogated for an access restriction notice in response to a user command to transmit the electronic message (step 52), and a detected access restriction notice is responded to in accordance with a prescribed transmission policy (step 58).
