When the calling party of external network does not know callee's the address of internal network or number, the calling party at first connects with the scheduling switching device, the scheduling switching device the prompting in have following 3 kinds of modes provide the prompting allow it find callee's address or number, carry out recall then.Finish the scheduling switching and be connected by the scheduling switching device according to different situations again.

At first, the scheduling switching device has secondary or dial signaling module repeatedly, the secondary of this module special disposal signaling or repeatedly dial and store forwarding.This module is made up of scheduling switching device end and client.The scheduling switching device has scheduling switching device end, and client is built in the calling party.The implementation that this module is concrete is as follows:

(1) calling party does not have the module that two-stage dialing is called out that is used for of built-in scheduler switching device.The calling party can only carry out two-stage dialing according to the prompting of scheduling switching device, and is switchable to the manual operation platform, by manual operation platform and operating personnel on behalf of switching.

A. the calling party has exhaled logical scheduling switching device by signaling Q.931, suppose that the calling party does not have the built-in secondary or the client of dial signaling module repeatedly this moment, when secondary or repeatedly the server end of dial signaling module learn after connecting with the calling party convenient with set up H.323 in the middle of be used for transmitting voice and video RTP multimedia passage send voice and video to the calling party, voice content is as follows: request 0 as the need human relay working, otherwise ask live callee's extension number, video content is blue picture for black font and the background of having write " request 0 as the need human relay working, otherwise ask live callee's extension number " printed words.

B. the calling party heard or only needed when seeing this content by by sending 0 on 0 on lower keyboard or the program to the scheduling switching device this moment, after receiving this dialing information, the scheduling switching device just directly forwards the manual operation platform to, at this moment caller is convenient can directly carry out the audio frequency and video conversation by connection and the operating personnel that set up just now, operating personnel can inquire that the calling party needs with which callee to converse or be connected, when the calling party informs callee's number or IP address or name or other relevant information, operating personnel just can send instructions TRANSFER to the scheduling switching device, after the scheduling switching device is received this instruction, if judge according to the information of receiving the callee, if number or name or other relevant information, just the direct number of query scheduling switching device (address) administration module, find callee's corresponding IP address according to number or name or other relevant information, if the IP address just need not be inquired about.

C. follow, the scheduling switching device sends Q.931 SETUP signaling request and the callee connects, the callee receives that Q.931 Q.931 this just send the CALLPROCEEDING denoting signaling after SETUP signaling and handling this connection, if confirm then to be ready to accept this connection then can send Q.931 that the CONNECT signaling connects.Dispatch switching device and just connect with the callee this moment.Dispatch switching device then and just the calling party all is transmitted to the callee by all voice and video data messages that the RTP passage sends, simultaneously also the callee all is transmitted to the calling party by all voice and video data messages that the RTP passage sends, like this calling party and callee communicate by letter and session has just been set up success.

(2) B/S framework.The calling party is the module that is used for the two-stage dialing calling of built-in scheduler switching device.The scheduling switching device is after connecting with the calling party, and the scheduling switching device can return to calling part user (called) tabulation, selects callee user by the calling party, and the realization calling party is connected with the callee's.

A. the calling party has exhaled logical scheduling switching device by signaling Q.931, this moment the calling party built-in the secondary or the client of dial signaling module repeatedly, when secondary or repeatedly the scheduling switching device end of dial signaling module learn and connect with the calling party.Scheduling switching device end just sends the USERLIST signaling to the secondary or the client of dial signaling module repeatedly, and user's (called) tabular form is as follows:
