Concrete, the flow process of this method may further comprise the steps as shown in Figure 2:
Concrete, as shown in table 1, VoIP Server stored calls information is example with the time that internal number, PSTN outer net number and calling take place.VoIP Server can also store other information, for example the number of calls of PSTN outer net number.
Table 1
| The storehouse comprises information | Variable name |
| Internal number | ?Sub_Num |
| PSTN outer net number | ?Pstn_Num_Out |
| Call out the Time of Day that takes place | ?Setup_Time_Out[n] |
VoIP Server also can carry out burin-in process to canned data, the call information in storage scheduled time corresponding or the pre-determined number for example with extension or outer net number, will be above the outer net call information deletion of the scheduled time or pre-determined number, the perhaps call information that i.e. deletion sends provide stored calls information to Tandem Gateway after.
Concrete, Tandem Gateway carries PSTN outer net number in the query requests that VoIP Server sends, as shown in table 2.
Table 2
| Gateway carries information | Variable name |
| PSTN outer net number | ?Pstn_Num_In |

More specifically, the method for the calling clawback that application scenarios of the present invention provides as shown in Figure 3, may further comprise the steps:
If a plurality of numbers or call record are repeatedly arranged, note number of calls m; Record system time Sys_Time this moment; Obtain Time of Day scope Inter_Time[n]=Sys_Time-Setup_Time_Out[n].
For example, ivr server puts prompt tone for the PSTN external user: " request extension number, as inquiring about the extension number information of dialing your phone recently, please by the # key! ".
Preferably, overtime repeating step 303; Jump to step 304 by the # key; Directly dial extension number and jump to step 307.
" inquiry information on the same day is by No. 0 key, and the information of inquiring about nearest fate is totally lost by the # key please by nearest fate, returns by the * key for ivr server prompt for example! ".Get back to step 303 by the * key; Jump to step 305 by user key-press 0 or fate.
The fate key that step 305, recording user are pressed also is stored among the variable day_n.
For example, ivr server offers the user according to the extension of obtaining selected by the IVR prompt tone:
" you have n telephone call register, listen in the process and can return by the * key:
Xx branch during xxxx xx month xx day xx: the completely restricted extension number is Sub_Num (1)
Xx branch during xxxx xx month xx day xx: the completely restricted extension number is Sub_Num (2)
……
Xx branch during xxxx xx month xx day xx: the completely restricted extension number is Sub_Num (n)
Hard of hearing please by 0, return by the * key, or directly import extension number and finish by # number "
By 0 repeating step 306; Jump to step 304 by the * key; The input extension number jumps to step 307.
