An originating user equipment may generate a request to utilize a service that links over-the-top content with a voice call, and may provide the request to an entitlement server of a core network associated with the originating user equipment. The originating user equipment may receive, from the entitlement server, information verifying entitlement of the originating user equipment for the service. The information may include a tag identifying the service. The originating user equipment may provide an invite message, with the tag, to a terminating user equipment and may establish the voice call with the terminating user equipment based on providing the invite message and via an Internet protocol multimedia subsystem (IMS) network and the core network. The originating user equipment may establish, concurrently with the voice call, a connection for the over-the-top content with the terminating user equipment via a data network and the core network.

Systems and methods for providing called devices with sets of context data associated with communication sessions are disclosed. In one implementation, a method for generating context data associated with a communications session may include receiving, from a calling device at a first subsystem, a request to establish a communications session. The request may include a first identifier associated with the calling device. The method may further include receiving, at a second subsystem, activities data associated with the calling device that transmitted the request to establish the communications session. The activities data may include a second identifier associated with the calling device and may be indicative of device activities of the calling device. In addition, the method includes determining, using the first identifier and the second identifier, that the received activities data is associated with the calling device that transmitted the request to establish the communications session, generating context data associated with the communications session based on the received activities data, generating visual content based on the generated context data, and establishing the communications session in response to receiving, from a user of the called device, an input command to accept the request.

Signaling system for public switched telephone network (PSTN) using a blockchain system. In one embodiment, a method is provided. The method includes determining that a phone call related operation between a first telecommunications operator and a second telecommunications operator was requested. A public switched telephone network (PSTN) comprises the first telecommunications operator and the second telecommunications operator. The method also includes updating, by a node of a blockchain system, a distributed ledger to indicate that the phone call related operation between the first telecommunications operator and the second telecommunications operator was requested. The method further includes analyzing the distributed ledger to determine if the phone call related operation was approved. The method further includes executing the phone call related operation in response to determining that the phone call related operation was approved.

A system and method of providing caller identification (ID) over a public switched telephone network (PSTN). For outbound calls, the system and method enable a caller to provide a caller ID that differs from the native caller ID of their mobile phone. The system and method enable multiple phones tied to a single account to display the same caller ID for outbound calls. For forwarded inbound calls, such as calls being forwarded from an office, the system and method inform the recipient of the identification of the call as well as that the call is being forwarded. The system and method enable the recipient to have calls forwarded from more than one number and identify the identity of the caller as well as the specific number the call is being forwarded from.

A computer-implemented method of for optimizing cellular network performance including identifying a plurality of voice call records stored on an application server in a first type of cellular network. The method includes analyzing call data associated with the plurality of voice call records, and identifying a set of fall back voice call records. The call data for each voice call record of the set of fall back voice call records includes a fall back indicator indicating that each voice call was initiated using a second type of cellular network. The method includes analyzing cause codes in the call data associated with the set of fall back voice call records and determining, based on the cause codes, a value for at least one KPI associated with the second type of cellular network.

Methods and systems described in this disclosure receive a call from a device associated with a caller and request an indication of a context of the call. The system can send a request for authentication credentials in a push notification to the device. The push notification can be linked to an authentication tab or page in an application. After authentication of the caller, the system can direct the application to cause a tab or page associated with the subject matter of the call to be displayed on the qualified device.

A system and method for integrating an existing telephony system of a business with various other existing communication equipment in a unique sequence and using call servers to facilitate voice calls to be made over data networks between businesses and customers for the purpose of low cost customer service provision. The system and method comprises a business connecting voice calls over data networks to customers registered in a dedicated directory using a digital to analog converter to convert the existing telephony system format of the business into digital format to transmit digital packets to the call server which will function as a telephone switch and connect the call to the customer and customers making voice calls over data networks to the business using the directory. Customers use a computer or mobile application which transmits digital packets to the call server which will connect the call through the converter, converting the format from digital to analog, to existing telephony system.

The originating user equipment may establish, concurrently with the voice call, a connection for the over-the-top content with the terminating user equipment via a data network and the core network.

A client device determines that a telephony outage is occurring. The client device connects to an on-premises telephony node using an encrypted password at the client device. The client device accesses a set of telephony services via the on-premises telephony node.
