Description
The present invention relates to a kind of centralized call of manual operator participation that under use virtual net (Centrex) situation, do not require and reply the also method and the device of automatic telephone switching.Realize that the user externally announces one or a few telephone number (being called pilot number), the outer incoming call of group all can be concentrated by this device and be replied and switching realization conversation automatically, improve the success rate of forward call greatly, promote corporate image, externally make things convenient for the propaganda of user on various propaganda materials such as business card, medium, sample, website No. one
Virtual net is a kind of centrex service, claim centrex again, virtual switch, virtual Private Branch Exchange PBX, the remittance line is logical, Centrex, the function that realizes virtual switching network in public network is provided, it can set up BCG (Business Communication Group) with software engineering in public network, it is a logical groups on the software, it is notion on the software, be called the group, there is not physically actual subscriber exchange, be virtual, but on function, virtual net will originally be based upon the subscriber exchange net of user side and include in the public network, office exchange with public network comes alternate user switch (PBX), and it possesses all basic functions of subscriber exchange, also possesses all new business functions of public network.Fig. 1 is the communication mode of virtual net, and Fig. 2 is the communication mode of PBX, and as seen this communication mode of two kinds has the difference of essence, and every call gate of virtual net all has two numbers, and one is public network number (trombone), is exactly local number; One is virtual net completely restricted extension number (cornet), is generally two to four, is used for Internal call, be called extension, in fact " extension set " of virtual net inside is exactly the straight line phone of public network, is the phone of virtual net inside in order to give prominence to just, and we are called " extension set ".Whole virtual net is called the group, refers to the phone of this virtual net inside in the group, and the group refers to the phone that this virtual net is outer outward, and its dial mode is as follows:
Intra-group call: directly dial group interior extension, or go to another extension set (both can use cornet, and also can use trombone) by console.Converse between the user in the group and exempt from call rate.
Breathe out in the group: transfer to group's prefix earlier, dial any public network number (going out group mode has multiple) again, or go to the outer phone of group by the operator.Go out groupcall operation and PBX roughly the same.Converse between user and the outer user of group in the group and collect by existing telephone network expenses standard.
The outer incoming call of group: the outer user of group can directly dial group Local Number of interior arbitrary extension set (use trombone), also can go to group interior extension set by certain virtual net group's operator.
Virtual net has many advantages, concerning telecom operators, reduces the influence of subscriber exchange to the public network call completing rate, promotes phone to distribute telephone numbers, and has embodied intensification, scale; Concerning the user, expenses such as setting up the required machine room of subscriber exchange net, equipment, attendant, networking flexibility, but strange land networking have been saved, realize strange land (as being in) office, professional various, the specialized maintenance can to produce speech channel not congested because of the trunk line lazy weight, synchronous with the public network technology, can have ISDN, adsl feature, be convenient to high speed Internet access, realize broadband data communication.Therefore the telecom operators in many places begin to remove subscriber exchange, the repacking virtual net.
But along with the use of virtual net, some new problems of virtual net have also produced, and for example the user must announce many different numbers on business card, medium, sample, website, and are promptly inconvenient, are unfavorable for that also the user with unified image externally; The user uses the telephone number of subscriber exchange for many years, propaganda for many years, and many clients, associated personnel know, or only know this number, change this number and can bring very big inconvenience and loss.At present, when handling these new problems, user or adopt many different numbers stand the disunity of inconvenience and corporate image, or the arrangement operator is on duty, uses the telephone set human relay working.
But phone can produce following problems by human relay working:
1. during owing to the virtual net switching, need the switching of the office exchange of a series of switching actions and public network
Mode is accurately mated, but the manual operation error is inevitable, office exchange tolerance model
Enclose mode complexity little, switching, be difficult to accurate coupling, cause the success rate of human relay working not high,
Make communication influenced, user's interests incur loss.
2. the operator leaves the post busy a moment, and phone just can't be answered.
3. the phone reception work is subjected to the influence of the artificial mood of operator.
4. night or festivals or holidays, or payment overtime pay, arrange the special messenger on duty, or phone just nobody connects
Listen.
5. to pay operator's wage, welfare, the expense of medical treatment, increase user's burden.
6. operator's work dullness is uninteresting.
These problems have hindered the popularization of virtual net, have influenced the call completing rate of public network.Searching does not require that under the virtual net environment centralized call of manual operator participation is replied and the method and apparatus of automatic telephone switching has been pendulum problem demanding prompt solution in face of telecom operators and user
