Embodiment

[0028] see image 3 , the system structure includes five parts: a SIP server 302, a SIP soft terminal 301 realized on a PC, a SIP gateway 303, a telephone terminal 305 (which can be any telephone terminal), a call target 304 (which can be any telephone terminal).

[0029] and figure 1 The difference of the shown system is that the SIP gateway 303 is used to respond to the transfer request of the SIP soft terminal 301, and initiate a call to the call target 304 (equivalent to the called terminal 104), while the telephone terminal 305 (equivalent to the user terminal 103) Neither receive nor participate in the signaling interaction of transfer.

[0030] Assume that the following usage scenarios exist: the SIP soft terminal 101 and the user terminal 103 belong to the same user, the SIP soft terminal 101 is an application software working on a PC, and the user terminal 103 is a telephone supporting the SIP protocol. see figure 1 . In this case, it is cumbersome for the user t...

Abstract

The invention relates to a technology using soft telephony to realize SIP calls. The invention discloses a click dialing proxy call method based on initial session protocol, including the following steps: A. selecting a called terminal on the SIP soft terminals and specifying to call through the user terminal; B. the SIP soft terminals buffer the number of the called terminal, and starting to call user terminals; C. after the user terminal is off hook, the SIP soft terminals transmitting SIP request switched to the called terminal to the user terminals; D. user terminal receiving the SIP request, and then initiating calls to the called terminal, and simultaneously finishing the talking with the SIP soft terminals; E. after the called terminals is off hook, the user terminal establishing a normal call with the called terminal to complete the proxy call process. The invention also discloses a device for realizing the method.

Description

technical field [0001] The present invention relates to an initial session protocol (Session Initiation Protocol, referred to as SIP) technology, in particular to a technology for realizing SIP calls by using a softphone. Background technique [0002] In unified communication services, click-to-dial has become a distinctive service. Users can click and initiate a target call after logging in to client software or a web page. At present, the realization of a typical click-to-dial application generally initiates a request through a web page or other client software, so that the server initiates a call to the calling party and the called party in turn, and after the call is connected, the two calls are associated to realize the call of the two telephones , this solution is mainly used in the field of consulting services for various websites. For a more detailed description, refer to Chinese patents with application numbers 200510080261.X and 200710188210.8. [0003] At present...
