Analogue relay interface control method

Abstract

Present invention relates to computer communication technology, specially referring to IP voice processing technology. Present invention technical proposal is put forward a control simulation interface off hook method, in FXO port and FXO port set binding relation speech-sounds gateway, when gateway detect FXS port user off hook , searching said FXS port corresponded FXO port, through software controlling said FXO port off hook. Present invention ensures user dialing habit and solves wrong charging problem through software controlling FXO interface off hook.

Description

technical field [0001] The invention relates to computer communication technology, in particular to IP voice processing technology. Background technique [0002] In the IP voice network (VOIP), the voice gateway is connected to the office switch or commercial switch through the FXO (Foreign Exchange Office external exchange office, also known as the analog trunk interface) voice interface, so as to access the public telephone switching network PSTN, complete External telephone calls in and calls out; Voice Gateway connects the user's telephone set in the IP network through the FXS (Foreign Exchange Station, external exchange station) voice interface, and completes the incoming and outgoing calls of the user's phone in the IP network. The network environment schematic diagram of the present invention is as follows figure 1 shown. Because telephone users are generally not used to the two-stage dialing method, in the above application environment, the voice gateway realizes di...

Problems solved by technology

However, there is a problem with the above application technology at present, that is, when an outside line user calls its bound FXS interface user from an idle FXO interface, when the FXS user corresponding to the FXO interface on the gateway is busy (for example, busy in a network call), if the FXO interface It does not know that the corresponding FXS user is busy, and at the same time, in order not to perform billing, the gateway will not take any action until the called party picks up the hook, so that the calling user always hears the ringback tone, which on the one hand causes the calling user to be due to Passively and blindly waiting for the called party to pick up the phone and waste time, on the other hand, it may cause the misunderstanding that the called party deliberately does not answer the phone

[0003] In the prior art, in order to solve the above-mentioned problem that the called user is busy and the calling user always hears the ringback tone, some gateways adopt software to control the FXO interface to go off-hook first, and then hang up to send the busy tone. The problem caused is that the bureau will bill the calling user
