Problems solved by technology

[0004] The existing call forwarding service has the following disadvantages: the service operation mode is single, which cannot meet the diverse needs of users; because the hook switch operation is very sensitive to time, it may lead to user misoperation; with the increasing pressure of operators to reduce costs The larger the number, the phone provided by the operator to the end user often does not support flashing the hook switch, resulting in the inability to use the call forwarding service; the core network has not activated the call forwarding authority, and the end user cannot use the call forwarding service

Abstract

The invention provides a call forwarding method and system, and an IPPBX. The method comprises the following steps: a second IP call terminal establishing a call with a first IP call terminal sends a call forwarding service code to the IPPBX in a double-audio multi-frequency DTMF mode according to the call demand of the first IP call terminal; the IPPBX determines to enter call forwarding service according to the call forwarding service code, and establishes a call connection between the second IP call terminal and a third IP call terminal corresponding to a call forwarding number according to the call forwarding number that is received again; the IPPBX establishes a call connection between the first IP call terminal and the third IP call terminal when receiving a hang-off request of the second IP call terminal so as to realize call forwarding. Therefore, diversified user demands can be satisfied, no user fork spring flapping operation is required, and in the case that a core network does not open the call forwarding authority, the user can still use the call forwarding service.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a call transfer method, system and IPPBX. Background technique [0002] With the development of unified communications, people have higher and higher requirements for the use of services, and the requirements for using methods are also becoming simpler and simpler. For example, for the use of value-added services, when using the same service, it is required that the core equipment can support users in a variety of ways. [0003] In the VOIP network, the traditional call transfer method is as follows: user A calls user B, and after user B picks up the phone, AB talks normally; hangs up, BC communicates normally; user B hangs up, and user AC communicates normally. [0004] The existing call forwarding service has the following deficiencies: the business operation mode is single, which cannot meet the diverse needs of users; because the hook switch operation i...
