Issue Description
A user dials the access code of the VU switchboard and then dials an extension number. The call is connected. When the user dials 0 to transfer to the attendant service, the call connection takes a long time.
Handling Process
Step 1 Obtain the VU script used on site. View the information "PlayCollect 512,512,251,true,4,'#','*','0','#',30,NumLen,calledNum" in the VU script for processing the transfer to the attendant service. Check whether the eighth parameter 0 (in bold) contains single quote marks. If the parameter contains single quote marks, delete them. That is, change the information to "PlayCollect 512,512,251,true,4,'#','*',0,'#',30,NumLen,calledNum".
Note:
The correct configuration is that the parameter 0 contains no single quote mark.
Step 2 If the fault persists, contact Huawei technical support engineers.
----End
Root Cause
The possible cause is that the VU script configuration is incorrect.
