The subject of the present invention is a method for establishing a telephone connection between a first terminal of a user and a second terminal of a contact, the infrastructures of the first operator and the second operator being connected to a call server the user moreover disposing of a virtual call number, the correspondence between said first physical call number and the virtual call number being recorded in said database of the call server, said method comprising: the allocation of at least one technical number to the second physical call number through the call server, the recording in the database of the call server of the association between said second physical call number and said technical number, when a call or a mini-message is sent to said technical number from the first terminal or to said virtual number from the second terminal, telephonically connecting the first terminal and the second terminal by means of the transmission of the call or the mini-message, by the call server, destined for the first physical call number or, respectively, for the second physical call number.

Telecommunications systems and methods having a mapping server; a communication network; and a mapping database in communication with the mapping server via the communication network, the mapping database associating telephone identifier data strings (which identify a target telephone device) with numeric telephone identifiers; the mapping server is configured to match numeric telephone identifiers of a source telephone of a caller and a target telephone of a callee with respective telephone identifier data strings using the mapping database; the mapping sever is configured to initiate an electronic communication between the source telephone and the target telephone; the numeric telephone identifier of the target telephone is masked to the caller using the target telephone identifier; the mapping server is configured to locate the target telephone device by the telephone identifier data string to provide a Global Positioning System display of the target telephone device on a screen of a source telephone device.

According to an embodiment of the disclosure, a toll-free telecommunications validation system determines a confidence value that an incoming phone call to an enterprises' toll-free number is originating from the station it purports to be, i.e., is not a spoofed call by incorporating one or more layers of signals and data in determining said confidence value, the data and signals including, but not limited to, toll-free call routing logs, service control point (SCP) signals and data, service data point (SDP) signals and data, dialed number information service (DNIS) signals and data, automatic number identification (ANI) signals and data, session initiation protocol (SIP) signals and data, carrier identification code (CIC) signals and data, location routing number (LRN) signals and data, jurisdiction information parameter (JIP) signals and data, charge number (CN) signals and data, billing number (BN) signals and data, and originating carrier information (such as information derived from the ANI, including, but not limited to, alternative service provider ID (ALTSPID), service provider ID (SPID), or operating company number (OCN)). In certain configurations said enterprise provides an ANI and DNIS associated with said incoming toll-free call, which is used to query a commercial toll-free telecommunications routing platform for any corresponding log entries. The existence of any such log entries, along with the originating carrier information in the event log entries do exist, is used to determine a confidence value that said incoming toll-free call is originating from the station it purports to be. As a result, said entities or enterprises operating a toll-free number may be provided a confidence value regarding an incoming telephone call, and using that confidence value, further determine whether or not to accept the authenticity of the incoming telephone call and/or based on said confidence value, service the incoming call differently.

Optimizing a number pool for dynamic number insertion (DNI) used for call attribution is achieved by considering physical characteristics of the DNI number assigned to a specific channel versus characteristics of consumers within that channel—such as by identifying more optimum DNI number characteristics and modifying a DNI number pool based on the more optimum DNI number characteristics—in order to make more optimized DNI number assignments.

Described herein is at least one non-transitory computer-readable medium comprising instructions to direct at least one processor to utilize a global dialing format. The at least one processor is directed to retrieve a phone number stored on a communication device. The retrieved phone number is converted to the global dialing format by a reformatting sequence or a manual intervention sequence and the reformatted phone number thereby obtained is saved to a global contacts list on the communication device. A local phone number is retrieved from the reformatted phone number when a user selects the reformatted phone number for dialing. The local phone number is in a destination country. A call logic sequence is initiated to assemble the dialing protocol necessary to complete the phone call. An authentication sequence is executed to confirm that the local phone number is an actual phone number in the destination country. The authentication sequence results in an authenticated local phone number which is concatenated with the dialing protocol assembled by the call logic sequence. A concatenated phone number is obtained. The retrieved phone number is saved to a call log in the global dialing format. The concatenated phone number is called.

One or more aspects of the disclosure relate to various functions and processes related to routing of calls based on origination and/or destination information. In one aspect, a method may comprise receiving a request for a call session, and the request may include an indicator that may indicate whether to route a call based on origination and/or destination information of the call session. Based on the indicator, a routing element may determine whether the call session should be routed based on origination information and/or destination information.

A calling user initiates a telephonic communication with a receiving user by dialing a phone number of the receiving user in his or her address book. The communication is transmitted from the calling user's device to the receiving user's device through a network that is not using Internet protocol or Internet-based, e.g., Transmission Control Protocol (TCP), Internet Protocol (IP), TCP-IP, or Voice over Internet Protocol (VoIP). After a number of notifications has passed on the receiving user's device and the receiving user is not able to answer the telephonic communication, a local voicemail recorder will be activated to record and store the telephonic communication for later retrieval by the receiving user. The stored communication is identifier by a sequence of string containing at least one of a name, a telephone number, a storage location, a date-time attribute, and a duration associated with the stored communication.

Techniques for connectivity using a geographic phone number are described. According to various implementations, techniques described herein enable various policies pertaining to the use of telephone numbers at different locations to be enforced. For instance, techniques described herein enable a client device that is outside of a permitted geographic area for a geographic phone number to use a non-geographic phone number to connect a call, while the call can be routed using the geographic phone number.

A method for predicting fraudulent call activity is provided. The method includes receiving one or more datasets indicating call activity corresponding to a phone number, and analyzing the one or more datasets to identify unusual call activity. The method further includes generating a fraud prediction, based at least in part on the identified unusual call activity, that the phone number will be used for fraud.
