Description

The bridge-set of network telephone exchanger and network phone system

Technical field

The present invention relates to a kind of bridge-set and network phone system of network telephone exchanger, relating in particular to a kind of regular phone switch upgrades that can make is the bridge-set and the network phone system of network telephone exchanger.

Background technology

Known, present black phone or mobile phone the be separated by distance of two places of person to person that can in communication, further.So black phone or mobile phone are the epochmaking meanss of communication during we live.But, because black phone or mobile phone no matter be domestic call minute to charge, still overseas call to charge second, all can allow the user when paying telephone charges, be difficult to accept the expense of costliness.So some user will utilize the time (as after midnight) of telecommunications company's defined to make a phone call, it is preferential just to have reducing the price of telephone charges.

Because prosperity of network at present and the feature that not limited by the region thereof have been released the networking telephone, and Skype, MSN, AOL, Peer-Call, IP phone are for example arranged.These networking telephones can allow the user carry out distance communicating by network, and some networking telephone only needs the payment network usage charges and need not prop up and charge for telephone usefulness, and the user can save many telephone chargess and uses like this.

But at present the networking telephone of the overwhelming majority can only could use the feasible inconvenience that still exists in the use during simultaneously on computer or IP phone next door as calling party and recipient on the market.

Content of the present invention

The objective of the invention is to solve above-mentioned defective, avoid defective to exist.The present invention redesigns network phone system, makes general telephone exchange upgrade to network telephone exchanger so that regular phone can with networking telephone mutual communication.Except can saving telephone charges, can also allow the user convenient when using the networking telephone like this.

The present invention proposes a kind of bridge-set and network phone system of network telephone exchanger, utilize bridge-set and telephone exchange to be connected with computer to form the network switch, after the regular phone dialing, through telephone exchange, bridge-set, computer, be connected to the internet through router again, thereby with internet specific communication protocol phone (Skype, MSN, AOL, YAHOO, Peer-call) or the Internet communication protocol phone (SIP (Session Initiation Protocol, Session initiation Protocol) phone) connects, to reach the purpose of network remote conversation.Long-range internet specific communication protocol phone (Skype, MSN, AOL, YAHOO, Peer-call) also can be connected to router by the internet with the Internet communication protocol phone (SIP phone), be connected to computer through router, be transferred to regular phone through bridge-set to telephone exchange again, equally also can reach the purpose of network remote conversation.
