Abstract: Systems and methods of determining whether to invite an entity to join a social networking system review a user's communications activity on a telephony system, and analyze that activity to identify entities with whom the user communicates. Those entities are then invited to join a social networking system that the user is a member of. The entities may also be invited to form a link with the user on the social networking system.

Abstract: Systems and methods of recommending that two parties form a link on a social networking system use activities conducted by the first party on a telephony system and information contained in contact or link lists stored for the second party on the social networking system to determine if the two parties are likely acquainted. If a comparison of this information indicates that the parties are likely acquainted, or at least are acquainted with common third parties, a recommendation that they form a link on the social networking system is issued to one or both parties.

Abstract: Systems and methods of recommending that two people form a link on a social networking system uses activities conducted by a first person on a telephony system to determine the names of individuals and businesses that the first person has communicated with through the telephony system. This list of names and individuals is then compared to the names of individuals and businesses that are members of the social networking system. If the first person is communicating with individuals or businesses who are members of the social networking system, a recommendation that they form a link on the social networking system is issued to one or both parties.

Abstract: Systems and methods of updating information in a user's contact list or address book on a telephony system make use of information drawn from the user's contact or link information stored on a social networking system. The telephony system obtains the user's credentials on the social networking system and accesses the user's contact or link information on the social networking system directly.

Abstract: Systems and methods of recommending that two people form a link on a social networking system use activities conducted by the two people on a telephony system to determine if the two people are likely acquainted. If it appears that both parties are calling each other, or if both parties are placing or receiving calls from common individuals, a recommendation that they form a link on the social networking system is issued to one or both parties.

Abstract: Systems and methods for recommending that a business deliver an advertising message to an individual make use of information about the individual's activity on a telephony system. The information about the individual's activity on the telephony system can indicate that the individual is in communication with certain types of businesses. The information can also indicate the timing of those communications. This information is used to recommend that similar businesses send advertising messages to the individual. The information can also be used to recommend that the advertising messages be delivered at certain times.

Abstract: Systems and methods of recommending that two people form a link on a social networking system use information for a first person that is obtained from a contact list or an address book that is maintained for the first person on a telephony system. The information drawn from the first person's contact list or address book is used to determine if any individuals or businesses listed in the first person's contact list or address book are members of a social networking system. If so, a recommendation that the first person form a link on the social networking system with those individuals or businesses is issued to one or both parties.

Abstract: A method for packet telephony includes receiving over a packet communication network (22) a first message originating from a first end-user (32A) in a first aggregating organization (28) to place a call to a second end-user (32D) in a second aggregating organization (30). Responsively to the first message, respective values are assigned to one or more security attributes that are indicative of a likelihood that the call is a spam call. A second message is transmitted over the packet communication network toward the second end-user, the second message containing at least one of the respective values that was assigned to at least one of the security attributes.

Abstract: Information, such as advertising, is presented to VoIP users (12) via a combination of telephone and data streams during session initiation via an IP phone or a personal computer (18). A proxy server (20) that receives the call request coordinates with a media server (30) to transmit targeted advertising to the caller during the post dial delay interval. After the advertisement concludes, the call continues normally.

Abstract: A method for telephony includes receiving at a facility of a telephone service provider a first subscriber request to place a first call to a specified telephone number. A provider request is sent to a remote server (26), which maintains a database (28) of records associating telephone numbers with respective packet network addresses, for a record (72) indicating a packet network address to which calls to the specified telephone number should be placed. Upon receiving the record from the remote server, the record is stored in a local cache (42) at the facility of the telephone service provider. After storing the record, upon receiving at the facility of the telephone service provider a second subscriber request to place a second call to the specified telephone number, the record is read from the local cache and is used in placing the second call to the packet network address.

Abstract: A method and system for a server side detection of a Network Address Translation (NAT) device is provided. During the server-side NAT determination process, the client device is not required to have knowledge of the type of NAT device that the client device is behind. The server side NAT determination process may include comparing between the address information that is embedded by the client device and address information as obtained by units within the server-side NAT detection device.
