In the utility model, as follows to the audio frequency and video treatment step:

(1), audio collection: the analog audio information that is sent by IP phone machine telecommunication unit is sent to central processing control unit, carry out analog-to-digital conversion and Filtering Processing after, forward the data compression part to;

(2), data compression: the audio-frequency information that collects is carried out data compression by central processing control unit;

(3), network communication: the voice data of finishing after the compression is sent to RJ45 network interface processing unit by central processing control unit, be sent to long-range IP phone machine through the Internet, simultaneously, the voice data after remote I P telephone set also will compress is sent to this machine, carries out two-way transmission;

(4), data decompression: the remote I P telephone set that RJ45 network interface processing unit receives is sent to central processing control unit and carries out decompression by the voice data that the Internet sends, and is reduced into original audio-frequency information, and carries out voice reproducing;

(5), voice reproducing: the voice data that is partly sent by data decompression that will constantly receive is reduced into analog information, carries out playback by the receiver of IP phone machine;

(6), information Control: various control informations such as the off-hook that the central processing control unit reception is sent by the IP phone machine, on-hook, dialing, ring, the operation of control whole software.

The utility model operation principle as shown in Figure 2, after the IP phone machine inserts the Internet by RJ45 processing unit 11, at first to login or register a unique identification, after carrying out identification authentication by IC-card read-write control unit 12, the RJ45 processing unit will be kept the marquis and be detected the connection request that remote I P telephone set is sent, receive connection request after, will on Video Controller, show and come electrosemaphore, and, make the IP phone machine begin ring to IP phone machine conveying bell signal.After the user picked up a receiver, the IP phone machine formed off hook signal, will transmit a connection signal to remote I P telephone set by RJ45 interface processing unit, and communication process begins.Behind the end of conversation, user's on-hook, this on-hook signal interrupts and being connected of remote I P phone network, stops audio collection and playback function, after while remote I P phone is received this hang-up signal, also can do same operation.Process of user calling is: the user picks up a receiver, network is received off hook signal, there is not connection request this moment, therefore network changes awaiting digit state over to, wait for subscriber dialing, after subscriber dialing is finished, network will check whether the user who is called out is online according to the number that the user dialled, not online voice of user of not online then loopback, if the user is online, just obtain this user's the network address, send connection request to this user, and loopback ringback tone, wait for replying of remote I P telephone set, in case user's off-hook of calling out just begins communication process once.

The utility model efficiently solves the existing existing problem of IP phone.This device combines the operation convenience of IP phone processing capacity and telephone set, the IP phone machine is inserted the Internet by the RJ45 processing unit, read a little controllers by IC-card and carry out identification authentication and charging, realize dialing, audio frequency and video communication and data compression process, send words and receiver playback function.This is a kind of implementation of cheapness, can utilize existing resource to greatest extent.
