摘要:
A communication system includes an application server including logic to receive preference data for each of a plurality of data record entries of a subscriber record from a telephone number mapping (ENUM) server, and to determine a contact sequence including a plurality of Uniform Resource Identifiers (URIs). The contact sequence is based at least in part on the received preference data.

A mechanism is provided for recovering from a catastrophic failure that results in a large number of user endpoints attempting to come on line simultaneously after an NGN is restored. In an enhanced DNS load balancer, DNS queries from the user end points relating to a particular NGN edge device are selectively dropped if a rate of queries for the particular edge device suddenly increases or exceeds a threshold. The query dropping may also be based in part on the class of service assigned to the user endpoint.

A sender is identified based at least in part on originator identification information associated with an incoming communication. A message recipient is then determined based at least in part on the identified sender and one or more databases associated with message recipients by comparing the originator identification information to one or more entries in the one or more databases. The incoming communication is routed to the determined message recipient of a shared mailbox of a unified messaging system. An intended recipient is identified among the owners of the shared unified messaging mailbox owners. Only the determined message recipient is notified of the deposited message, based on the dynamic information derived from each deposited message.
摘要:
Example methods and apparatus to control synchronization in voice over Internet protocol (VoIP) networks after catastrophes are disclosed. An example border element comprises a network interface to receive a VoIP network registration request message from a VoIP endpoint, a catastrophe detector to determine whether a catastrophe has been detected, a backoff time module to compute a backoff time using a priority assigned to the VoIP endpoint and an expected number of VoIP network registration request messages, a recovery module to determine whether the VoIP endpoint is currently registered with the VoIP network, and to send a response message having a header representing the backoff time to the VoIP endpoint when the catastrophe has been detected and the VoIP endpoint is not currently registered with a VoIP network, and a signaling processor to process the VoIP network registration request message when the VoIP endpoint is currently registered with the VoIP network.
摘要:
Methods and apparatus to provide a network-based caller identification (CID) service in a voice over Internet protocol (VoIP) network are disclosed. An example method comprises receiving a session initiation protocol (SIP) communication session initiation request message comprising an early-media indicator, disabling a ringtone generator, sending a SIP ringing message containing a session descriptor in response to the early-media indicator, receiving a ringtone based on the session descriptor, and presenting the ringtone to alert a user of a requested communication session.
摘要:
A method for customization of communication session request notifications based on user preference information includes receiving a communication session invitation at a service provider. The service provider determines the intended target of the invitation, and identifies preference information associated with the target. In an embodiment, the preference information is associated with a user of the target communication device. The preference information includes a set of identifiers for multimedia content associated with particular users, groups, regions, or the like, or any combination thereof. Based on the session invitation, the service provider determines a particular identifier and provides the associated multimedia content to the target device. The preference information can be adjusted by a user to customize notifications for requests from particular users, groups, or regions, or any combination thereof.
摘要:
A system that incorporates teachings of the present disclosure may include, for example, a computer-readable storage medium including computer instructions for receiving an emergency request to assist a subscriber, retrieving presence information of each of a plurality of parties that serve as emergency contacts for the subscriber, selecting a communication identifier of at least one of the plurality of parties according to the presence information, and notifying the at least one party of the emergency request. Additional embodiments are disclosed.
摘要:
Methods and apparatus to route a communication session directly to a voicemail mailbox are disclosed. An example method includes receiving a communication session initiation message from a caller at a source telephone number, the communication session initiation message including a destination telephone number and a direct voicemail feature identifier, determining that the direct voicemail feature identifier indicates that the caller requests that the call be sent to a voicemail mailbox associated with the destination telephone number, and forwarding the call directly to the voicemail mailbox associated with the destination telephone number without ringing the destination telephone number.
摘要:
A technique for scheduling conferences includes receiving a conference request, which includes an invitee list, a prioritized list of preferred media types, and one or more times for a conference associated with the conference request. The conference is requested with respective invitees associated with the invitee list (via respective subscriber terminals) and it is determined whether the respective invitees can be scheduled for the conference. The conference is scheduled between a conference requester (associated with the conference request) and available ones of the respective invitees, when mandatory attendees, included within the respective invitees, are available.
摘要:
A client of a telephone number mapping (ENUM) server is used to protect the ENUM server from a Denial of Service (DoS) attack. The DoS attack may comprise a plurality of attempts to place exception calls from one or more end user devices that are unregistered. The one or more end user devices may originate from a service provider network.
