Call connection is established with first called terminal, realizes normal talking.It should be noted that in the present embodiment, work as server
100 receive after the first called idle state reports information, call calling terminal, but calling terminal is in busy state, then
Server 100 can directly cancel this call back on busy service as needed or timing is called next time, the number of calls
Then cancel business during more than setting value (for example, 3 times).
Further, in order to meet the needs of user subscribes to multichannel calling back when busy, calling terminal is in calling in call shape
First called terminal of state and after subscribing to call back on busy service can also call another or multiple in talking state
Called terminal simultaneously subscribes to call back on busy service, and server 100 then can be according to predetermined callback strategy successively calling in the free time
Multiple called terminals of state.
Fig. 3 is refer to, by the flow diagram for the calling back when busy method that another embodiment of the present invention provides.The present embodiment
In calling back when busy method in, calling terminal calling in talking state the first called terminal and subscribe to the first called terminal
Call back on busy service after, and have called the second called terminal in talking state and have subscribed the busy of the second called terminal
Call back service, when definite first called terminal is in idle condition, used callback strategy is server 100：According to
The subscription time of the call back on busy service of one called terminal and the second called terminal determines calling sequence.As shown in figure 3, with it is upper
One embodiment is compared, and is established between the calling terminal and first called terminal before call connection, the present embodiment
In calling back when busy method further include：
S201, receive the calling terminal for confirm subscribe to the second called terminal call back on busy service second confirmation
