With reference to Fig. 2, in step 210, call direction callee make a call, and described calling is sent to the first gateway.
In a step 220, the first gateway obtains described calling from calling party, and the imitate request signal of described calling is converted to IP request signal, then, the IP request signal of conversion is transmitted to dispatching host machine via n (n >=2) individual predetermined network respectively.
In step 230, dispatching host machine receives the IP request signal that the first gateway forwards for described calling from each predetermined network of a described n predetermined network, and each IP request signal received is transmitted to the second gateway via the predetermined network forwarding this IP request signal respectively.
In step 240, the second gateway IP request signal that receiving scheduling main frame forwards for described calling from each predetermined network of a described n predetermined network, and each IP request signal received is reduced to imitate request signal respectively, thus the n road call request obtained for described calling, and the n road call request of acquisition is transmitted to callee.
In step 250, callee obtains the n road call request forwarded for described calling from the second gateway, and make response respectively for the n road call request obtained, thus obtain for the n bar response message of described calling, the every bar response message obtained is fed back to dispatching host machine via the predetermined network of the second gateway and the IP request signal that forwards the response of this response message respectively.
It should be noted that, in above-mentioned steps, the first gateway, dispatching host machine, the second gateway are configured with n predetermined network interface card all respectively, and by the individual predetermined network interface card of the n of configuration, the first gateway, dispatching host machine, the second gateway are accessed a described n predetermined network all respectively.
In addition, in the embodiment shown in Figure 2, described method also comprises: if dispatching host machine is in response to a response message in the n bar response message of described calling, and the voice channel set up on the predetermined network of IP request signal forwarding the response of this response message between calling party and callee, then dispatching host machine abandons other response message for described calling, to guarantee only there is a real voice service when network condition is good.
For increasing the redundancy backup quantity of calling further, m (m >=2) platform can also be set in the embodiment shown in Figure 2 and configure identical dispatching host machine, and every platform dispatching host machine all accesses a described n predetermined network by n predetermined network interface card of each self-configuring, such second gateway can obtain the m × n road call request for described calling, correspondingly, callee can obtain the m × n bar response message for described calling.
In addition, for guaranteeing only there is a real voice service when network condition is good, in the above-described embodiments, described method also comprises: also can set up hot standby relation between m platform dispatching host machine, like this when the dispatching host machine first (or preferential) in described m platform dispatching host machine is in response to during for a response message in m × n bar response message of described calling, this dispatching host machine enters master state for described calling, and utilize the hot standby relation between m platform dispatching host machine to send heartbeat packet to other dispatching host machine in described m platform dispatching host machine, need not go again to process the response message for described calling to notice other dispatching host machine.
