This application discloses a method for establishing a call connection, a first terminal, a server, and a storage medium. The method includes: obtaining, by a first terminal, a second vocoder list of a second terminal, the second vocoder list including vocoders supported by the second terminal and with corresponding priorities; determining, by the first terminal, a first vocoder with the highest priority among vocoders that exist in both a first vocoder list of the first terminal and the second vocoder list, the first vocoder list including vocoders supported by the first terminal and with corresponding priorities, and the priorities of the vocoders being positively correlated with audio frequencies in encoding and decoding of the vocoders; and requesting, by the first terminal by using the first vocoder, to establish a first call connection to the second terminal.

Enablement of a voice channel being established between an IoT device and a controller through the use of a voice-line service system.

Meeting and conferencing systems and methods are implemented in a variety of manners. Consistent with an embodiment of the present disclosure, a meeting system is implemented via a computer server which is configured to provide a web-based meeting-group subscription option to potential meeting participants. A meeting scheduling data is received over a web-accessible virtual meeting interface. The meeting scheduling data includes group identification information and meeting time information. In response to the group identification information, participant identification information is retrieved for participants that subscribe to a meeting group identified by the group identification information. Chat sessions may be used by the meeting participants.

Systems and methods for handling an incoming telephone call received at a private branch exchange system and directed to an employee enable an actual or virtual receptionist to camp the call on the employee's extension. When the call is camped on the employee's extension, the private branch exchange system causes a push notification to be sent to a telephony device used by the employee to notify the employee that a call is camped on his extension. Such a push notification may also inform the employee about how many calls are camped on his extension. Further, such a push notification may provide the employee with information about the identity of a calling party whose call is camped on the employee's extension.

Programmatically reversing numerical line identity presented at a communications services gateway into named IP Telephony users with prior association, delivers dynamic reverse address resolution switching connections from ground to cloud, permitting any conventional telephone to dial and connect to any associated IP Telephony endpoint in the world, without changes to the conventional telephone. Reversing line identity into associated named users bridges both the addressability and economic divide between mass conventional paying (mobile and fixed) and free. IP Telephony networks. A system for supporting communications between a user on an IP-addressed-communications-device and a telephony subscriber device, the telephony subscriber device having a corresponding telephone number, includes: one or more service nodes configured to: receive from the user the telephone number of the telephony subscriber device and create an association from the telephone number to the user, wherein the association allows the telephony subscriber device to connect to the user.

Call recording in an Internet telephone system is provided. A dual-mode terminal includes a call server interworker for, when a cellular call commences, determining whether it is possible to access a call server which controls Voice over Internet Protocol (VoIP) calls; a recording interface processor for, when it is possible to access the call server, setting a connection to a recording server; a recorder for generating recording data packets comprising a cellular phone conversation; and a data communicator for transmitting the recording data packets to the recording server.

The subject of the present invention is a method for managing the reception of a telephone call signal on a communication terminal, with a view to the establishment of a telephone link, said telephone link being established by way of a server, said called communication terminal being able to receive the telephone call signal according to at least two modes, comprising a voice mode, in which the telephone link between the called communication terminal and the server is ensured by way of a telephone communication network, and a data mode, in which the telephone link between the called communication terminal and the server is ensured by way of a network for data communication according to a Voice over IP technology, said method comprising the direct selection, by the user of the method, of the mode of establishment of the telephone link. The method comprising the allocating by a call server of a temporary number to the calling communication terminal.

A telephone system is provided for transmitting telephone signals between first and second mobile stations. The system includes a first internet protocol interface configured to receive an incoming cell phone signal generated by the first mobile station and to transmit the phone signal to the internet. A second internet protocol interface is configured to receive the phone signal sent through the internet by the first internet protocol interface and to transmit the phone signal to the second mobile station, such that users of the first and second mobile stations can engage in a conversation where the phone signals are communicated over substantial distances through the internet.

A call routing system for use with a wireless telephone systems is disclosed. The system, which monitors the subscriber's current physical location, determines the device to which a call should be terminated, and routes the call. The device can be any IP telephone, including a cable television system adapted to IP telephony. The system routes calls without direct subscriber actions, without a second telephone number, regardless of the time of day and day of week. Various options can also apply to a call, determined by subscriber-established preferences, when specified criteria are met, or calls can be limited to/from specified telephone numbers. The system and method uses signaling techniques that will allow routing of the call, along with any authorization or restrictions, to be done remotely from the actual switching of the call. Call events are transmitted to the call routing system while the communications path of the call is held at the switching system awaiting call routing information. The identity of the subscriber is established using existing means that are used to authenticate the user. The wireless phone user does not have to enter any additional codes or identification to obtain access to the call routing system.
