A method for establishing a temporally following voice connection of a user of a call center facility to the call center facility after a temporally preceding voice connection of the user to the call center facility has been established and has ended, wherein the temporally following voice connection relates to the temporally preceding voice connection, includes: in a first step, the temporally preceding voice connection between the user and the call center facility is established; in a second step that follows the first step, the temporally preceding voice connection is ended; in a third step that follows the second step, a text-oriented message is transmitted to the user, wherein the text-oriented message indicates the possibility of establishing the temporally following voice connection that relates to the temporally preceding voice connection; and in a fourth step that follows the third step, the temporally following voice connection is established.

For a safe handling of text messages (MesT) received by a communication device (CD) owned by a user, an application server (AS) receives a request (Req) from the communication device (CD), the request containing an identifier (IdCD) of the communication device and presence data (DatP) indicating that the communication device is associated with a service entity (SE) via a wireless session, the service entity (SE) being a vehicle, receives a text message (MesT) having the user as recipient, and sends a message (MesC) to a network server (NS), the message (MesC) including at least a part of the content of the text message (MesT), the network server (NS) generating a voice message (MesV) from the content of the message (MesC) and providing the voice message (MesV) via an audio call to the communication device (CD).

To enable multiple message originators to share an SMS shortcode, originator identifying codes can be added to outbound SMS messages that prompt recipients to respond with response messages that include the originator identifying codes. The originator identifying codes can be added by a service provider that administers the SMS shortcode. When a response message is received on the SMS shortcode number, the service provider processes the response message content to extract the originator identifying code. The code and, optionally, a recipient ID can be used as a lookup to determine the intended originator that the response message is for. The response message can then be associated by the service provider with the correct originator for subsequent processing.

A method for exchanging content among communication entities over a communication network includes: checking for a trigger command along with the saved content in a memory of a first entity (510), identifying at least one second entity with which the content has to be exchanged (520), enabling a handshake message from the first entity, upon identifying the trigger command, to the second entity ensuring about the appropriate decoding block (530), converting the saved content of the first entity into symbols until a termination character is encountered (540), wherein the converted symbols are sent as deliberately terminated call(s) through a set of permissible unique identifier(s) to the second entity and translating one or more intervals of the duration of the call of the deliberately terminated calls (one Subscriber Identity Module (SIM)) or the unique numbers (more than one SIM) into unique symbols at the second entity to form a message (550).

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.

A communication appliance has a processor, a data store, a display screen, an interface to a wireless network, a microphone, and software executable from a machine-readable physical medium, wherein the software provides a function for comparing incoming audio signals with signals stored in the data store as trigger signals, and a function for initiating an action or sequence of actions in response to recognizing an incoming signal as a trigger signal.

A sender telephone receives a text message to send to a receiver telephone. The sender telephone determines the transmission delay time by sending a predetermined message to receiver telephone, based on the time it receives an address complete message and a release message. The sender telephone determines a constant value that is greater than the transmission delay time and in response to the determining the constant value, ringing the receiver telephone to transmit the received inputted text message. A receiver telephone receives a predetermined message from a caller telephone to determine a transmission delay time, based on the time it receives the address complete message and a release message. The receiver telephone determines a constant value that is greater than the transmission delay time. The receiver telephone receives incoming rings from the caller telephone and converts the received rings into a text message to be displayed.

A method for establishing connection is provided. The method includes following steps. A call is established between a first mobile device and a second mobile device. A connection-assisting item is shown on the first mobile device. When the connection-assisting item is selected, the first mobile device sends a first text message having a first format to the second mobile device. An agree-to-establish-connection item is shown on the second mobile device. When the agree-to-establish-connection item is selected, the second mobile device is connected to a server through which the first mobile device further establishes a connection with the second mobile device.
