Description

The method of a kind of quick refusal loop trunks blacklist incoming call

Technical field

The present invention relates to a kind of method refusing loop trunks incoming call, particularly relate to a kind of when loop trunks equipment receives blacklist calling number, loop trunks equipment is by outside line off-hook, and the method for refusal relaying incoming call fast, belongs to dispatching communication technical field.

Background technology

Loop trunks (also known as analog junction) equipment does not adopt signaling, directly uses the communication equipment of ordinary telephone line transferring voice and data.When outer office's call outside line, the outside line ALERTING message reception incoming call that loop trunks equipment connects by detecting it.Because loop trunks equipment does not have signaling, the equipment that continues in the loop, by before outside line off-hook, cannot discharge this calling.As long as the caller of incoming call is permanent, can hear ring-back, the outside line meeting ring always of calling, until ringing timeout just can discharge this calling always.In this case, the loop trunks equipment be connected with outside line can be occupied again and again, cannot active call release.Other want the calling of this loop of incoming call also cannot incoming call because outside line does not discharge.Following problem is had when reality uses:

No matter as shown in Figure 1, continue in the loop in equipment, be that DID(directly enters mode) or BID(two-stage dialing mode), when the blacklist caller incoming call that loop trunks equipment configures, loop trunks equipment is occupied after outside line ring.It is analyzed calling number and conforms to the blacklist of loop trunks Equipments Setting, loop trunks equipment can be discharged, and at this moment not by outside line off-hook, so or outside line cannot be stopped ring.Outside line can only ring always, and loop trunks equipment will continue occupied.After loop trunks equipment is occupied, it analyzes the blacklist of calling number and loop trunks Equipments Setting again.After calling number conforms to blacklist, again loop trunks equipment is discharged.So repeat to circulate down, until calling subscriber oneself is hung up, and loop trunks equipment also can only be occupied again and again, cannot once incoming call be discharged always.

Summary of the invention

For the deficiency existing for prior art, technical problem to be solved by this invention is the method providing the incoming call of a kind of quick refusal loop trunks blacklist.In the method, loop trunks equipment can directly by outside line off-hook, refusal relaying incoming call fast.

For realizing above-mentioned goal of the invention, the present invention adopts following technical scheme:

A method for quick refusal loop trunks blacklist incoming call, is characterized in that: when calling subscriber is by outer alignment loop trunks equipment incoming call, described calling subscriber takies described loop trunks equipment;

When the blacklist of described loop trunks Equipments Setting conforms to calling number, discharge described loop trunks equipment, then by described loop trunks equipment by after outside line off-hook again by outside line on-hook, this time end of calling.

Wherein more preferably, after described calling subscriber takies described loop trunks equipment, described loop trunks equipment detects calling number according to External Call.

Wherein more preferably, described loop trunks equipment is compared according to the blacklist of described calling number and described loop trunks Equipments Setting.

Wherein more preferably, the step of loop trunks equipment release External Call comprises further:

Described loop trunks equipment is by outside line off-hook;

The corresponding incoming call of calling subscriber becomes talking state;

Described loop trunks equipment is by outside line on-hook, and release External Call, calling subscriber hears busy tone.

The present invention, when blacklist caller is permanent, directly once by outside line on-hook, prevents blacklist caller circulation incoming call from taking the resource of loop trunks equipment.

Accompanying drawing explanation

When Fig. 1 is blacklist caller incoming call loop trunks equipment in prior art, in the permanent situation of caller, repeatedly take the schematic flow sheet of loop trunks equipment;

When Fig. 2 is blacklist caller incoming call loop trunks equipment in the present invention, the schematic flow sheet of refusal incoming call fast.

Embodiment

Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.

The method of quick refusal loop trunks blacklist provided by the invention incoming call not only can be applied to dispatching patcher, can also be applied to the calling system not having dispatching desk.Be described in detail for calling system below.

This calling system comprises loop trunks equipment, outside line and caller phone, and loop trunks equipment comprises loop trunks plate and loop trunks processing module, and wherein loop trunks plate and loop trunks processing module are known prior aries, do not repeat them here.When the calling subscriber calls outside line of outer office phone, the outside line ALERTING message reception incoming call that loop trunks equipment connects by detecting it.Loop trunks equipment can be always occupied, until calling party telephone on-hook is just released.

In order to prevent calling subscriber from repeatedly taking loop trunks equipment, the invention provides the method for a kind of quick refusal loop trunks blacklist incoming call, being used in calling subscriber in analogue loop incoming call process.When calling subscriber is by outer alignment loop trunks equipment incoming call, this calling takies this equipment.Loop trunks equipment according to its concrete configuration, when blacklist is consistent through comparing with calling number, by after outside line off-hook again by outside line on-hook, until calling subscriber hears calling busy tone, this time end of calling.Be described in detail below.

When calling subscriber is by outer alignment loop trunks equipment incoming call, no matter be that DID(directly enters mode) or BID(two-stage dialing mode), this equipment is occupied after outside line ring.Loop trunks device analysis goes out calling number and conforms to the blacklist of loop trunks Equipments Setting, and first by outside line off-hook, then by outside line on-hook, calling subscriber hears busy tone, and this calling directly terminates.Concrete measure as shown in Figure 2, comprises the steps:

1) calling subscriber calls outside line key, outside line ring;

2) the loop trunks equipment Inspection be connected with outside line is after ring, and the calling of this calling subscriber takies corresponding loop trunks equipment;

3) after outside line ring, outer line interface receives FSK(frequency shift keying) calling number;

4) loop trunks equipment occupied after, loop trunks plate detects calling number and notifies loop relay process module;

5) blacklist list of calling number and this loop trunks Equipments Setting is compared by loop trunks processing module, judges whether calling number conforms to the blacklist caller of this loop trunks Equipments Setting, if conformed to, then discharges loop trunks equipment.

6) loop trunks equipment first passes through loop trunks plate by outside line off-hook, and now this equipment is by becoming talking state between outside line and calling subscriber, then by loop trunks plate by outside line on-hook;

7) calling subscriber hears busy tone, refuses this incoming call, end of calling.

In the present invention, when calling subscriber conforms to the blacklist caller of loop trunks Equipments Setting, after this calling subscriber's incoming call, this equipment passes through loop trunks plate by the on-hook again of the first off-hook of outside line, calling subscriber hears busy tone, avoid caller permanent when, the blacklist caller incoming call repeatedly that circulates takies the problem of loop trunks equipment again.

Above the method for quick refusal loop trunks blacklist provided by the present invention incoming call is described in detail.For one of ordinary skill in the art, to any apparent change that it does under the prerequisite not deviating from connotation of the present invention, all by formation to infringement of patent right of the present invention, corresponding legal liabilities will be born.
