Symptom
The PSTN analog trunk is connected to the FXO port on the OSU board of the IAD132E(T). The original number of the analog trunk is 58836176. The access code of the UAP/CTI is 4006113006. A user can dial the original number or the access code. After dialing the access code, the user is connected to the IVR where the user can select the agent service. If the user dials the access code, 000 is displayed to the agent.
Network: PSTN analog trunk-IAD132E(T)-UAP3300
Cause
The possible causes are as follows:
•The calling number has enabled calling line identification restriction (CLIR) service.
•The receiving gain is not properly configured on the IAD132E(T).
Solution
1.Contact the carrier to check whether the CLIR service is enabled for the calling number.
1.If yes, disable the service.
2.If no, go to 2.
2.Run the dsp fsk gain command to lower the FSK gain gradually.
icon-notice.gif NOTICE:
Do not reduce the FSK gain to a large scale. Large FSK gain charge may make the IVR two-stage dialing function unavailable. For example, when the gain is reduced to -5, the calling number is displayed to the UAP3300 agent when a phone or mobile phone user dials the access code; however, when the gain is reduced to -7, the IVR two-stage dialing function is unavailable.
3.Check whether the fault is rectified.
1.If yes, the procedure ends.
2.If no, go to 4.
4.Contact Huawei technical support.
