A method for establishing a telephone call between an originating device and a destination device. A call server receives an originating call made by an originating device to a dedicated number for a destination party. In response to receiving the originating call: (i) the originating call is parked; and (ii) a message is sent to the destination device of the destination party. The message informs the destination device of the originating call to the dedicated number so that the destination device is able to call the call server to be connected to the parked originating call.

In the case of a method or an arrangement for the automatic start up of a first communication terminal (EG A, EG B) configured for voice communication on at least one second communication terminal (CL A, CL B) configured for text communication, the voice communication between communication terminals is conveyed via at least one voice communication server (SCS) and the text communication between communication terminals is conveyed via at least one text communication server (TCS). The at least one voice communication server (SCS) and the at least one text communication server (TCS) exchange information via at least one conversion device (GW). The start up of at least one first communication terminal (CL A, CL B) is effected via the at least one text communication server (TCS), the at least one conversion device (GW) and the at least one voice communication server (SCS) to at least one second voice communication terminal (EG A, EG B).

A network call method, a server, a call terminal, a network call system, and a storage medium are provided. The network call method includes: receiving a reservation request transmitted by a call reservation terminal, the reservation request including a first communication identifier of a first call terminal; generating a chat room identifier of a chat room in a social network application; generating a call reservation notification, the call reservation notification including an access link generated according to the chat room identifier; and transmitting the call reservation notification to a communication client of the first call terminal according to the first communication identifier of the first call terminal.

The at least one voice communication server (SCS) and the at least one text communication server (TCS) exchange information via at least one conversion device (GW). The start up of at least one first communication terminal (CL A, CL B) is effected via the at least one text communication server (TCS), the at least one conversion device (GW) and the at least one voice communication server (SCS) to at least one second voice communication terminal (EG A, EG B).

A telephone subnet crawler is used to access automated telephone response systems and index the information, contents and structure contained therein. A database of the information, contents and structure of a plurality of automated telephone response systems is created by the telephone subnet crawler. A user interface provides a waiting party with direct access to the information, contents and structure of the automated telephone response systems contained in the database. Where an automated telephone response system requires user input, the user interface calls the automated telephone response system and navigates to the node requiring user input, provides the user input and displays the results to the user. Where an automated telephone response system connects to an operator, the user interface calls the automated telephone response system, navigates to the node for an operator, and when an operator is detected, calls the user at a user provided callback number.

Systems and methods for delivering video emergency services using Rich Communication Service (RCS) protocols are disclosed. In some embodiments, a method may include: receiving, at a 9-1-1 dispatch system, a 9-1-1 text message sent via a computing device using an RCS protocol, and initiating a 9-1-1 video communication with the computing device following the RCS protocol.

The embodiment of the present disclosure provides a method for smart gas personalized feedback service and an Internet of things (IoT) system thereof. The method is implemented based on a smart gas management platform. The method includes: receiving a call message of a target customer through a call center, and a content of the call message being related to a gas business; determining a service category corresponding to the call message based on the call message, and determining a feedback mode; in response to the feedback mode being manual feedback, determining a target operator through the call center to feed back a call of the target customer; and in response to the feedback mode being automatic feedback, determining, using a knowledge map, a feedback content through the call center based on the service category corresponding to the call message, and sending the feedback content to the target customer.

Embodiments include a client device configured for telephone communications and including an application or software that configures the client device to, in response to receiving an input to initiate a telephone call to a selected contact, receive data of the selected contact. The client device determines a current time of the selected contact based on a location corresponding to the selected contact, and determine from the data of the selected contact and the current time an appropriate time to call the selected contact. A display generated at the client device includes a message comprising message data representative of the appropriate time to call the selected contact.
