Description
Technical field
The present invention relates to IP telephony system field more particularly to a kind of IP phone exchange system and exchange methods.
Background technology
With the development of the communication technology, the application of IP phone interchanger is more and more extensive.IP phone interchanger is in tradition
Digital SPC exchange on the basis of carried out technological innovation, be it first to emerging CTI (Computer speech lab)
Great support, and the more open and standard compared with traditional PBX are provided with VoIP.In recent years, with
The prevalence of Internet and the success of IP, the IP phone interchanger based on IP agreement come into being, and are expected to solve the program-controlled friendship of tradition
The deficiency changed planes.Due to being IP-based feature, the relatively traditional telephone exchange based on circuit of IP phone interchanger has peace
Dress deployment is convenient, flexible, convenient for strange land networking, strong antijamming capability, the advantages of limitation by phone network circuit.In recent years, with
It universal and cloud computing technology the development of the Internet, applications or even the high in the clouds telephone exchange based on internet and cloud computing occurs
Machine provides office communications application solution for enterprise.
However, existing IP phone exchanger extension call route method is the processing for having continued traditional SPC telephone exchange
Method, i.e., the number dialed according to extension set are judged by turn.Meanwhile existing IP phone interchanger and traditional program controlled telephone exchange
Machine does not have the ability for judging mobile phone ownership place.Thus the main problem brought has：
Outside line can just be dialed by dialing after outside line needs dial out office code (being usually 0 or 9).The problem of bringing in this way is
The no unified codes and standards of setting of office code, different users and equipment all can be different.If it is not known that go out office code
It just can not normally dial outside line.When dialing domestic phone number, artificial judgment home zone of mobile phone number is needed, to nonlocal hand
Machine needs to dial 0 just can be with normal call.
Invention content
In view of the above problems, it is proposed that the present invention overcomes the above problem in order to provide one kind or solves at least partly
State the IP phone exchange system and exchange method of problem.
One aspect of the present invention provides a kind of IP phone exchange system, including：
Information unit is extracted, for receiving the call request information of terminal extension transmission, and is carried from call request information
The number and called number of terminal extension are taken, is sent to terminal extension exhalation permission judging unit；
Terminal extension breathes out permission judging unit, outer for judging whether terminal extension has according to the number of terminal extension
The number of terminal extension and called number if there is outer call right, are sent to intercom number judging unit by call right；
Intercom number judging unit for called number to be compared with preset intercom number, judges called number
Whether it is intercom number, if so, called number is sent to call business unit, if it is not, then by the number of terminal extension
Type of number judging unit is sent to called number；
Type of number judging unit, for judging whether called number is phone number, if so, number by terminal extension
Code and called number are sent to ownership place judging unit, if it is not, the number of terminal extension and called number then are sent to meter
Take mode judging unit；
Ownership place judging unit for called number to be compared with preset home zone of mobile phone number tables of data, obtains
Called number ownership place area code, and judge called number ownership place area code and terminal extension number attribution area code whether
It unanimously,, will if inconsistent if unanimously, the number of terminal extension and called number are sent to charging mode judging unit
The number and called number of terminal extension are sent to the automatic adding device of area code；
Charging mode judging unit, for judging charging mode according to the first place of called number and second-order digit, and
The number of terminal extension, charging mode and called number are sent to call business unit；
The automatic adding device of area code for adding area code before called number, and by the number of terminal extension and adds
The called number after area code is added to be sent to call business unit；
