The support of every voice veneer is respectively 2 or 4 ports, and the port type of support is FXS, FXO and E﹠amp; Three types of M, introduce the function of these three kinds of port types below respectively:

FXS interface finger print is intended user interface, be used for connecing the trunk interface of common simulation substation or switch, effect mainly provides line circuit interface, finish functions such as corresponding feed, ring, off-hook, on-hook, 2/4 line conversion, realization is to the access and the processing of analog voice signal, and the signal that will compress at last after handling is given main frame.

FXO interface finger print near-ring road trunk interface; be used for connecing the analog line of switch; effect mainly is corresponding ring detection, off-hook, protection, the conversion of 2/4 line an or the like function, realizes access and processing to analog voice signal, and the signal that will compress at last after handling is given main frame.

E﹠amp; M interface finger print is intended E﹠amp; The M trunk interface is used for connecing the E﹠amp of switch; The M trunk interface, effect mainly is the E﹠amp that finishes number of different types; The M signaling method is realized access and processing to analog voice signal, and the signal that will compress at last after handling is given main frame.

A DSP module is arranged respectively on each voice veneer, whether be used to discern actions such as user's off-hook, on-hook, dialing takes place, and can be by the VOIP conversation module of giving mainboard side with these event notices with mailbox public between the mainboard, simultaneously this DSP module can provide G.729A, G.723.1, the coding/decoding capability of type G.711.The embodiment of the invention is to be based upon on the basis of aforementioned prior art, and the DSP module that makes full use of on the voice veneer can be discerned the DTMF number, realizes on this VOIP conversation module.

Before the method for describing the described adjusting IP phone of embodiment of the invention speech volume size, set up the end-to-end voice channel of user A and B earlier, these are prior art, and it specifically comprises:

(1), telephone subscriber A plucked phone, the speech interface plate detects the off-hook action of user A, this signal is passed to the signal processing of mainboard side VOIP conversation module on second voice router 13.

(2), the VOIP conversation module is notified the DSP module playing alert tones on the voice veneer, the wait subscriber dialing.

(3), after the user dials phone number, these telephone numbers are collected and are stored by the VOIP conversation module.

(4), after collecting the target pattern that enough telephone numbers can mate a setting, telephone number or be mapped to an IP main frame by a dial plan mapper, perhaps on GK server 14, inquire about the pairing purpose IP of this telephone number address, i.e. first voice router 12 by second voice router 13.

(5), the VOIP conversation module is moved session protocol H.323 and set up a passage that sends and receive speech data for the connection that each has purpose IP address on IP network.

(6), the VOIP conversation module activates the encoding and decoding that connect two parties A, B, and uses RTP/UDP/IP as communication protocol stack.

Promptly finish the common talking state of user A, B by above step, hypothesis user A need regulate the IP phone volume below, is described the embodiment of the invention from amplifying the volume that local terminal answers and dwindling two aspects of volume that local terminal answers respectively below:

Embodiment one: amplify the volume that local terminal is answered

The first, the user sends and contains the DTMF number of regulating the instruction of IP phone volume and give DSP module in the voice veneer;

After user A uses IP phone and user B to enter communication process, when needs amplify the speech volume that local terminal answers, user's needs are double fast, and (the requirement telephone set must be the dual-tone multifrequency phone by " * " key on the telephone set, do not provide support for pulse telephone), the time of twice continuous button was controlled within two seconds.Why will be controlled at the time within 2 seconds is because " * " key may be employed the function button use of program as other, when the user uses IP phone, connectedly may require user A to carry out the process of interactive operation according to the information of voice prompt operation push-button to end subscriber B, the user may need at first to import " * " key or " # " key, " * " key or " # " key of this moment need send the opposite end to, or local terminal carries out some other processing, not as amplifying the function button that local terminal receives speech volume, the function button sequence of therefore using two quick continuous " * " keys to operate as amplification of volume.

The second, the DSP module is discerned this DTMF number and is notified the VOIP conversation module of mainboard side to read this DTMF number.

After the DSP module is discerned this DTMF number, the DTMF number that identifies is given in the public mailbox that DSP module and VOIP conversation module can visit, send an interruption to mainboard side simultaneously, the VOIP conversation module of notice mainboard side reads this DTMF number.

Three, after this VOIP conversation module reads this DTMF number, issue and regulate the IP phone volume and instruct this DSP module.

After the VOIP conversation module reads first " * " number button, at first apply for the timer in one two second, receive " * " number button merely and can not judge that the amplification of volume function key still needs the function key of other processing, therefore use timeout mechanism to distinguish.If within two seconds, receive the function key that " * " number button is just thought amplification of volume again, delete the timer in 2 seconds; If what receive is " # " number button, just think that rigidly connecting " * " number button of receiving is misoperation, neglect " * " number button, delete the timer in 2 seconds, then enter for the first time the processing procedure that receives " # " number button; If what receive is digital keys, just delete the timer in 2 seconds, directly according to " ' * ' number key+numerical key " carry out other processing; If in two seconds, do not receive any button, just think that this " * " number button is to need processed conventionally button, not the function button of regulating volume.

If in the time in two seconds, receive two " * " number buttons continuously, enter voice channel and regulate in the volume process, abandon this two buttons, after this whenever receive " * " number button, earlier " * " number key is discarded, notify voice veneer DSP module that sound is amplified simultaneously.

Four, this DSP module is revised and is used for parameter that the speech data after being encoded is decoded, again this speech data is reduced to voice signal and plays to the user.

The DSP module is just revised the parameter that decode operation uses, and it is regulated step-length and can be provided with, as regulating step-length 0.5dB or 1dB.Speech data behind the coding that the DSP module will be received from the IP network side joint uses that this amended parameter is decoded, play to user A after the D/A conversion, and local terminal has just received the voice that are exaggerated.In this process,, just withdraw from the process that the passage volume is regulated, with the digital normal process that receives if receive digital keys; If receive " # " number button, just handle according to receiving " # " number button for the first time, apply for the timer in one two second, wait for the common input that cooperates to come interpreting user of state of user key-press operation and timer.

Embodiment two: reduce the volume that local terminal is answered

After user A used IP phone to enter communication process with user B, when needs reduced speech volume that local terminal answers, the user needed double " # " key of pressing on the telephone set fast, and the time of twice continuous button also was controlled within two seconds.Its basic principle and embodiment one are similar, do not repeat them here.
