Disclosed embodiments provide improved communication between a caller and multiple parties. A caller performs a call spray operation on a group of contacts using an electronic communication device such as a mobile telephone. The call spray operation attempts to contact an electronic device associated with each contact in the group of contacts. If one of the contacts answers and is deemed to be a live user, then the remaining contacts that did not answer each receive a message on their associated electronic device indicating which of the contacts answered the caller with a live user. In this way, a group of people can be conveniently contacted and kept up to date with the status of the communication with the caller.

An SIP proxy server 1 includes a forking termination unit 21. The forking termination unit 21 is configured to: in response to receiving an Initial INVITE request message from a originating-side network 6, transmit the Initial INVITE request message to an incoming-side network 7, and in response to receiving an 18X response message at the first time from the incoming-side network, transmit the 18X response message received at the first time to the originating-side network 6. The forking termination unit 21 establishes Early dialog #0 between the SIP proxy server and the originating-side network 6 and establishes Early Dialog #1 that is compatible with an incoming-side terminal 3 that is a transmission source of an 18X response message received at the first time. In response to receiving 18X response message at the second time from the incoming-side network 7, the forking termination unit 21 establishes Early Dialog #2 that is compatible with the incoming-side terminal 3 that is a transmission source of the 18X response message received at the second time.

The invention provides a decryption method for a trunking group call and a user equipment. The method includes: monitoring group call data in a current cell and obtaining a hyper frame number being a first hyper frame number; when switching from the current cell to a target cell, obtaining the group call data and obtaining an interval range of a hyper frame number of the target cell according to the first hyper frame number, the hyper frame number of the target cell being a second hyper frame number; traversing the second hyper frame number according to the interval range of the second hyper frame number, obtaining a plaintext, and comparing group call session information contained in the plaintext with the group call data of the current cell; and if consistent, decryption by traversing the second hyper frame number being successful, carrying out a decryption operation according to the second hyper frame number.

A system and method for establishing communications enables an outbound communication to be made simultaneously across a plurality of different communications platforms. The system is configured to perform the following: receive from a user, a first request to establish an electronic communication with a contact; identify via the details of contacts stored in a storage device, a contact identifier of the contact for each of a plurality of the different electronic communications platforms; receive at a processor from the user, selected devices of the user with which to establish the electronic communication with the contact; transmit via one of the selected devices of the user, a second request to establish an electronic communication comprising real time audio data with the contact simultaneously via each of the plurality of the different electronic communications platforms using each respective contact identifier; receive via the communications device, an acceptance of the second request to establish an electronic communication with the contact via one of the plurality of different electronic communications platforms; and establish an electronic communication comprising real time audio data between the contact and the one of the selected devices of the user via the one of the plurality of different electronic communications platforms.

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 method applicable to a multi-subscriber identity module (SIM) call management process includes parsing, by a managed device, an incoming call to obtain call information, determining a communications circuit corresponding to a called identifier, and when the managed device has performed an incoming call shielding setting on the communications circuit in response to a remote management instruction sent by an entitlement server (ES), skipping responding, by the managed device, to an incoming call event, or receiving, by the server, a remote management instruction from the ES, and deleting or freezing routing information corresponding to an identifier in response to the remote management instruction such that a communications circuit corresponding to the identifier in the managed device is unable to respond to an incoming call event.

A connection manager manages connections for associated user devices by determining whether an incoming connection has been answered at a user device, and if so then generating and transmitting silencing commands to associated user devices using first and second wireless communication modes, with one mode being faster. Connections can comprise phone calls, and modes can comprise push and Bluetooth messaging. The connection manager can instruct device outputs to provide connection alerts, limited to visual alerts when an associated user device is active, listen for associated user device communications, and instruct device outputs to stop providing alerts when a silencing command is received. Further, a connection manager can receive a signal regarding a headset status, route an outside connection from a phone to the headset when the headset is active or to another device when the headset is not active, detect a change in headset status, and reroute the connection accordingly.

Techniques are described herein for providing call logs for cellular and internet calls that are rerouted to one or more terminating caller devices. The techniques include: organizing a call routing scheme based on call routing configuration settings, the call routing scheme directing routing of incoming calls to one or more user devices that receives service from a telecommunications network; receiving a call log request from a user device that includes a unique identifier of the user device or a user; transmitting the call log request to a database server of the telecommunications network to obtain a call log for an incoming call to the one or more user devices, the incoming call being routed according to the call routing scheme; and sending the call log to the user device to display the call log information at the user device.
