Abstract

The invention provides a session initial protocol (SIP)-based calling method, SIP-based calling equipment and an SIP-based calling system. The calling method comprises the following steps that: an SIP client transmits a registration message to an SIP server; the SIP client receives a Notify message with a user number diagram from the SIP server; and after receiving the dialing of a user, the SIP client matches a corresponding number scheme from the user number diagram for calling according to the dialing of the user.

Description

technical field [0001] The present invention relates to the communication field, in particular to a calling method, device and system based on SIP. Background technique [0002] FTTX's EASY operation and maintenance is the common goal of all operators, and it is also a concentrated expression of the competitiveness of each equipment manufacturer's solution. When the Next Generation Network (NGN) network is changed to FTTX, the use of Session Initial Protocol (Session Initial Protocol, SIP) to access the IP Multimedia Subsystem (IP Multimedia Subsystem, IMS) is faced with user local dialing rules, user digit maps, Operation and maintenance issues of number mapping. Especially in the mainstream operation of the industry, if the fixed terminal or fixed network access gateway adopts the current mainstream loose coupling (Loose Couple) processing method, then the operation and maintenance is simple, efficient, and the local user digit map distribution and operation and maintenan...
