A network that is to execute transcoding is fixed. IMS networks (SBC 1a and SBC 1b) set an information element that requests either of the IMS networks to execute transcoding into the SDP, and use that information element to select the IMS network (SBC 1a or SBC 1b) that is to execute transcoding between the IMS networks (between SBC 1a and SBC 1b). Then, the selected IMS network executes transcoding of media data.

A method for originating and terminating services in a unified communication platform is provided. The method includes receiving, from a local market intermediate carrier, a request for a communication between a subscriber of a public network and an end-user endpoint in a local network, associated with an end-user phone number. The method includes creating a lease for an address anchor in a pool of addresses, receiving, in a proxy server from a carrier gateway server, a communication request from the end-user phone number to the address anchor, and establishing a communication channel to the address anchor. The method includes replacing, in the communication channel, a from header with a phone number of the subscriber of the public network, and a to header with the end-user phone number. A system and a non-transitory, computer-readable medium storing instructions to perform the above method are also provided.

Methods, systems, and devices for wireless communications are described. Some wireless communications systems may transition between a real-time texting (RTT) mode and a text teletypewriter (TTY) mode and vice versa, on a user equipment (UE). A UE may make a determine to transition between two texting modes while coordinating the transfer of text data between the different modes. Some wireless communications systems may also transition a UE between a packet switched network and a circuit switched network without loss of signal and consistent text data delivery during the communication without losing the text data during the transition between the two coverage areas. Transitioning between modes and networks may provide a user with interoperability and the benefit of conveniently switching between two modes without service interruption.

A method includes determining that data out of a peripheral device has been interrupted. In response, control signals are transmitted that cause power to not be supplied to the peripheral device and then cause power to be supplied to the peripheral device. If the peripheral device is determined to not be outputting data, whether data into the peripheral device has been restored is determined. If it is not, control signals are transmitted that cause power to not be supplied to a router and then cause power to be supplied to the router. If the router is determined to be outputting data, control signals are transmitted that cause power to not be supplied to a wireless access point that is coupled to the modem and then cause power to be supplied to the wireless access point. Whether the wireless access point is outputting data is determined.

Disclosed are a method and system for interaction between an AP and a Modem. The method comprises: when an AP end sends a message to a Modem end, acquiring a service type corresponding to the message; searching, according to the service type, in pre-set multiple RILD threads for an RILD thread corresponding thereto; and sending the message to the Modem end through the RILD thread.

A cordless telephone that establishes a call with a telephone of a destination via a base unit includes a controller and a radio unit. The controller modulates control data for controlling radio communication and voice data to be transmitted to the telephone, and stores a modulation control signal of the control data and a modulation voice signal of the voice data in a half slot of a Digital Enhanced Cordless Telecommunications (DECT) system. The radio unit transmits, by radio, the half slot to the base unit.

An information processing system transmits and receives sound data through a switching equipment. The information processing system includes: a transmitting end image forming apparatus that has a facsimile function to transmit communication sounds through the switching equipment; a receiving end image forming apparatus that has a facsimile function to receive the communication sounds through the switching equipment; a controller that generates a sound recording start command to start a recording of the communication sounds, and transmits the sound recording start command to the receiving end image forming apparatus; and a sound recorder that starts the recording of the communication sounds in the receiving end image forming apparatus when the receiving end image forming apparatus receives the sound recording start command.

A network watchdog and reset device determines that a signal into a modem device has been interrupted. In response to determining that the signal into the modem device has been restored, the device transmits control signals that cause power to the modem device to be cycled. In response to determining that the modem device is outputting data, the device transmits control signals that cause power to a router device to be cycled. In response to determining that the router device is outputting data, the device transmits control signals that cause power to a wireless access point device to be cycled. In response to determining that the wireless access point device is outputting data, the device transmits control signals that cause power to a peripheral device such as a security camera to be cycled.

A method of operating a captioned telephone call in which an assisted user is connected by a captioned telephone device that is connected both by a first line to a remote user and a second line to a relay providing captioning for a conversation, the method comprising the steps of: when a start of an incoming call is detected by the captioned telephone device on the first line, the captioned telephone device automatically calling the relay on the second line to initiate captioning service set up; the captioned telephone device passing spoken words received on the first line to the second line; and the relay then providing text captions of the spoken words back to the captioned telephone device on the second line.
