Troubleshooting
2 Analyzing and Rectifying Faults
Huawei Proprietary and Confidential
Copyright © Huawei Technologies Co., Ltd.
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
Step 1 Contact the carrier to check whether the CLIR service is enabled for the calling number.
If yes, disable the service.
If no, go to Step 2.
Step 2 Run the dsp fsk gain command to lower the FSK gain gradually.
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.
Step 3 Check whether the fault is rectified.
If yes, the procedure ends.
If no, go to Step 4.
Step 4 Contact Huawei technical support.

2.1.9 When the IAD Is Connected to the IMS, the Calling Number
Cannot Be Correctly Displayed on Phones that are Connected to
the IAD
Symptom
The customer requires that the short number is displayed when on-net users make calls on the
IMS. However, the country code and the actual number are displayed no matter the call is
made between on-net users or from an off-net user to an on-net user.
Cause
The possible cause is incorrect IAD soft parameter settings.
Solution
Step 1 Run the display sip soft-parameter command to check whether the clip-mode value is PAI.
