A mobile application gateway configured to interconnect mobile communication devices on a cellular network with an enterprise network is provided. The mobile application gateway includes a voice and data signaling gateway configured to provide routing functionalities, service functionalities and admission control. A gateway GPRS support node (GGSN) is configured to establish a secure data session between one or more of the mobile communication devices and the enterprise network by establishing a GPRS tunneling protocol (GTP) tunnel between a carrier-hosted serving GPRS support node (SGSN) and the GGSN.

Techniques for preventing denial of call transfer are provided. For example, a method, comprises: indicating, in an apparatus, that a call pull is initiated; categorizing, in the apparatus, an access attempt occurred for the call pull as a mobile-terminated access attempt; and making, in the apparatus, the access attempt to a network by transmitting a message to enable a process for the call pull, wherein the message includes a cause value set according to the categorization of the access attempt. The method may be performed by a user equipment (UE).

In a call forwarding system, a management apparatus of the call forwarding system determines service terminals capable of near field wireless communication within a reception range of near field wireless communication, generates a terminal list, and receives a call event message reporting the receipt of a call from a reference terminal. The management apparatus may transmit a call report message including the terminal list to the reference terminal and the service terminals. The management apparatus may forward the call initially received by the reference terminal to a terminal which transmitted a receipt request message by transmitting a call forwarding request message to the reference terminal. The management apparatus may transmit, to the reference terminal and the service terminals, a receipt report message reporting the call was forwarded. According to a change receipt message or upon non-receipt by an intended terminal, the call may be reforwarded to another terminal.

An automated registration service supported on an application server that interoperates with an IMS (IP Multimedia Subsystem) core network is configured to dynamically register and deregister devices that are all associated with one or more commonly-utilized phone numbers. The service may assign the phone number to registered devices and, in contrast, un-assign the phone number from deregistered devices. The registration and deregistration of the devices may occur based on the amount of interaction with the device and other real-time contextual information. Furthermore, the automated registration service intelligently determines which registered devices to forward incoming video and/or audio calls to based on various contextual information, including the capabilities of device, identified location of a user, user preferences, etc. By intelligently selecting which devices should receive an incoming call, unnecessary use of bandwidth, data, and resources (e.g., battery power) can be reduced.

In some embodiments, a method receives a call from a caller device that is initiated via a first communication channel and directed to first contact information for a recipient's device. The call is forwarded using a call forwarding option to the computing device. Second contact information for the recipient's device is retrieved where the second contact information different from the first contact information used in the call. The method initiates a communication to the recipient's device using the second contact information via a second communication channel that is different from the first communication channel. The communication avoids triggering the call forwarding option for the recipient's device. The call is connected between the caller device and the recipient's device upon initiating the communication where the computing device is in a call path of the call and performs a call feature for the call.

A system may include a processor that may execute computer-executable instructions that cause the processor to receive caller information regarding an incoming communication from a caller and receive a request from a user to route the incoming communication to a virtual assistant application. The virtual assistant application is configured to interact with the caller and determine whether the caller is associated a fraudulent caller activity stored on databases accessible by the processor. The processor may then receive an indication from the virtual assistant application that the caller is associated with the fraudulent caller activity and forward the incoming communication to another party in response to receiving the indication.

A method and a call routing system (CRS) are provided for routing an incoming call made to one of multiple numbers of a user to a call receiving client application (CRCA) deployed on one or more user devices when the called number is not reachable. The CRS, in communication with the CRCA deployed on one or more user devices, sets up a user account using one or more of the user's multiple numbers. The CRS detects availability of the CRCA on one or more user devices over a data network to accept an incoming call. The CRS receives the incoming call made to one of the numbers, when the called number is not reachable. The CRS routes the incoming call to the CRCA on one or more user devices over the data network on detecting the availability of the CRCA on one or more user devices over the data network.

A conference service number system enables the reconfiguration of an existing telephone number as a service number usable for selectively routing calls to each of a client endpoint and a dedicated conference software instance. A conferencing system implements separate conferencing software instances for individual operators for whom unique telephone numbers, are assigned. A telephony system facilitates calls to and from telephone numbers and implements a menu system (e.g. an interactive voice response (IVR) menu) for presenting a caller with options to either route a call to a specific telephone number to the subject operator (e.g., to a client device of that operator) or to a conferencing software instance implemented specifically for that operator. The call is accordingly routed to either a device of the operator or to the conferencing software instance based on the selection by the caller.

A velocity of a device of a user is detected using one or more sensors of the device. If the detected velocity is within a first range, a determination is made that the user is driving. A presence update is transmitted to a server based on the detected velocity. The detected velocity may include altitude data. The server receives the presence update and updates a presence status based on the presence update. The server transmits a user interface (UI) output to a second device to update a user presence indication on a display of the second device.
