Embodiment Construction

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0018] The method for quickly rejecting incoming calls from the loop relay blacklist provided by the present invention can be applied not only to a dispatching system, but also to a calling system without a dispatching console. The following takes the call system as an example for detailed description.

[0019] The call system includes a loop relay device, an outside line and a calling phone, and the loop relay device includes a loop relay board and a loop relay processing module, wherein the loop relay board and the loop relay processing module are known The prior art is not repeated here. When the calling party of the external telephone calls an external line, the loop trunk device receives the incoming call by detecting the ringing message of the external line to which it is connected. The loop relay device will be occupied all t...

Abstract

The invention discloses a method for allowing a dispatching desk to quickly refuse a blacklist incoming call of a loop trunk, which comprises the following steps: making the incoming call by a calling subscriber to loop trunk equipment by the means of an outer wire, wherein the calling subscriber occupies the loop trunk equipment; releasing the loop trunk equipment when the blacklist configured by the loop trunk equipment conforms to the calling number, hanging on the outer wire again after the outer wire is hung up through the loop trunk equipment, and terminating the calling. According to the method, the problem of repeated occupation of the loop trunk equipment of the blacklist user after the incoming call of the blacklist user is refused is solved. In addition, after the blacklist user is refused, the outer wire is hung up at one time, so as to effectively avoid repeated occupation of the loop trunk equipment of the blacklist user.

Description

technical field [0001] The present invention relates to a method for rejecting an incoming call from a loop relay, in particular to a method for rejecting an incoming call from a trunk when the loop relay device receives a blacklist calling number, the loop relay device picks up the outside line The method belongs to the technical field of dispatching communication. Background technique [0002] Loop relay (also known as analog relay) equipment is a communication equipment that directly uses ordinary telephone lines to transmit voice and data without using signaling. When an outside phone calls an outside line, the loop trunk device receives the incoming call by detecting the ringing message of the outside line it is connected to. Since the loop relay device has no signaling, the call cannot be released before the loop relay device picks up the outside line. As long as the incoming caller does not hang up, he will always hear the ringback, and the outside line of the call ...
