A headset system (1) comprising a first telecommunication device (3) comprising a desk phone or a computer (4) with an installed softphone, a second telecommunication device, such as a mobile phone or a smart phone (6), and a headset (2) comprising a cord (5) with a first connector (7), by means of which the headset (2) is adapted to be interchangeably connected to the first telecommunication device (3) and the second telecommunication device (6). The headset system (1) is adapted to transfer a call from the first telecommunication device (3) to the second telecommunication device (6), when the first connector (7) is unplugged from the first telecommunication device (3). The invention also relates to An external device (8) comprising a second connector (31) to be attached to a first connector (7) of a headset (2), means (9, 10) for connecting the external device (8) to a personal computer (4) with a softphone installed on it, a controller (36) adapted to send a call transfer control signal to the softphone, when the first connector (7) is unplugged from the second connector (31), whereby an active call on the first telecommunication device (4) is transferred to a second telecommunication device (6).

A method and system for operating a multitenancy telephony system including a call queue that stores call requests received from a plurality of users; an expandable and contractible telephony resource cluster that establishes call sessions for call requests; a analysis system that calculates capacity requirements of the system; a resource allocator that manages the scaling and operation of the telephony resource cluster; and a plurality of telephony network channels that are used as telephony communication channels for call sessions.

Provided are a computer keyboard with a telephone keypad, and an electronic equipment, which relate to the technical field of computer peripherals and human-computer interaction. A main keyboard of the computer keyboard includes a nine-grid numeric key area; the telephone keypad is mapped to the nine-grid numeric key area, and is switched by a key Tel; a numeric keypad is also superposed and multiplexed in the inner nine-grid numeric key area, adopts an arrangement of 123 456 789, and is switched by a key NumLock; and further a scientific calculator is integrated with the computer keyboard. The computer keyboard is not only convenient for making a call, but also can achieve one-hand operation of a T9 input method, and can be used as a scientific calculator of windows 10.

In one embodiment, the method of processing telephony sessions includes: communicating with an application server using an application layer protocol; processing telephony instructions with a call router; and creating call router resources accessible through a call router Application Programming Interface (API). In another embodiment, the system for processing telephony sessions includes: a call router, a URI for an application server, a telephony instruction executed by the call router, and a call router API resource.

In a preferred embodiment, the method of caching media used in a telephony application includes: receiving a media request; sending the media request to a media layer using HTTP; the a media layer performing the steps of checking in a cache for the media resource; processing the media request within a media processing server; and storing the processed media in the cache as a telephony compatible resource specified by a persistent address. The system of the preferred embodiment includes a call router and a media layer composed of a cache and media processing server.
