Description
Technical field
IP phone and the system and method for talkback system intercommunication are realized by multicast the present invention relates to a kind of, particularly related to
And a kind of system and method that IP phone and talkback system intercommunication are realized by multicast.
Background technology
Talkback system is widely used in all trades and professions, a variety of different places：Airport, bar, building site, KTV, scheduling
Deng more noisy place.It should say the practicability higher of these local intercoms, act on bigger.
But the defects of intercom, is also obvious：It is exactly that speech range is short, everybody must can radiate in intercom
In the range of can just communicate.A scene is now simulated, for example there are Beijing and Shanghai Liang Ge branch companies in a company, when Beijing public affairs
Department needs to notify certain department intercom personnel of Shanghai company at once there are one emergency, that will how, traditional does
Method first passes through phone, and mail or other communication modes relate to the related personnel of Shanghai this side, and the related personnel in Shanghai is led to again
To the intercommunication group of certain department, this process is not only efficient but also indefinite etc. there may be reporting for intercom call in receiving and distributing
Problem.
With the fast development of network, IP (interconnection protocol between network) telephone system is gradually instead of traditional mould
Intend telephone system, the company that currently the majority has certain scale employs IP telephony system, if we have invented a kind of energy
The method of enough unicom telephone systems and talkback system, then with regard to issue noted above can be solved.Firstly reduce intercom
The quantity of equipment breaches the limitation of region and distance, realizes the direct dialogue of distal end personnel and intercom personnel, carries significantly
High efficiency.
It is well known that scheduling system plays very important role in certain industries, dispatcher by dispatching desk come
Contact and allotment telephone subscriber, mobile phone user, intercommunication unit resource, way traditional at present is that have dispatching telephone on dispatching desk,
Intercom, when needing to notify telephone subscriber then using dispatching telephone, need to notify intercommunication unit be then using intercom call,
Shortcoming is apparent：Controlling equipment is more, and operating process is cumbersome, and the interconnection that can not achieve telephone subscriber and intercommunication unit is mutual
It is logical.
In conclusion in the telecommunication of intercom, for telephone system and talkback system in scheduling system application
Interconnect that there are many deficiencies, so it is necessary to be improved.
