In practical application, the object of the invention gets around the voice protocol stack exactly, and the process of simulation conversation is directly utilized the driving interface of voice device to be implemented between the two voice mouths and accomplished call flow.It has broken through traditional to the VoIP intrinsic notion, does not have directly to use the voice protocol stack and the purpose that reaches telephone intercommunication.
In the application, in gateway terminal equipment, add a kind of configuration mode, i.e. test pattern.Under this pattern, will start voice driven automatically, and tackle all phone incidents, and, it not passed to the voice protocol stack, and only pass to the tone testing process like off-hook or on-hook.In the tone testing process, DSP (digital signal processor) and SLIC (SLIC) driving interface are carried out control and management, the operation of DSP and SLIC driving interface is realized fully the communication process of simulating reality according to incoming event, self state and time shaft.Particularly as shown in Figure 2, when A side's off-hook, the opposing party B can hear jingle bell, and A can hear ring-back tone, and like B side's certain hour off-hook not, then A side then hears busy tone, in a period of time, does not also have on-hook like A side, crosses can just can hear and urge the on-hook sound.After hearing jingle bell like B side, off-hook, then A side cuts off ring-back tone, and A, B both sides get into talking state.A or B on-hook, then both sides' dropped calls.Therefore the call flow process of simulation only needs just can realize in this product inside, does not need by external environment condition, reaches the actual effect that is simple and easy to usefulness.
Further, utilize present technique can realize not relying on the test of the voice device of environment such as voice protocol stack and soft switching server.Behind VoIP product electrifying startup, connect two phones, be configured to test pattern after, promptly get into testing process.One side plucks phone, and another phone is with regard to jingle bell, and when plucking time-out, both sides just can converse, and in whole communication process, the voice device are tested, and reach and test effect rapidly.
Main event handling process code in the method for the present invention is following:
That has adopted this invention realizes the method that simulation is conversed based on gateway terminal equipment; Because its main operation controller tone testing process; This tone testing process is tackled all phone incidents of described gateway terminal equipment, and based on described phone incident, the SOT state of termination and time shaft described digital signal processor and SLIC is controlled, thereby can be according to the phone incident of interconnective gateway terminal equipment; Control figure signal processor and SLIC are controlled; Realize the simulation conversation, thereby remove the soft switching server environment that to build in the prior art from, make the mode that realizes conversation more easy.In addition; Realize the method for simulation conversation based on this, the present invention also provides a kind of method that realizes that the voice device detects in the gateway terminal equipment, and audio detection equipment is connected in master controller and voice device; And in the process of simulation conversation; According to the tone testing process of described master controller, described voice device is carried out audio detection, thereby can realize in without the environment of soft switching server that the voice device detects; Be fit to be applied to the extensive automatic test of plant produced, effectively solve the problem of voice device detection inconvenience in the prior art with this.And of the present inventionly realize that based on gateway terminal equipment the application mode of the method for simulation conversation and the method that the voice device detects is easy, realize with low costly that range of application is very extensive.
In this specification, the present invention is described with reference to its certain embodiments.But, still can make various modifications and conversion obviously and not deviate from the spirit and scope of the present invention.Therefore, specification and accompanying drawing are regarded in an illustrative, rather than a restrictive.
