Users can receive international toll calls but cannot make international toll calls.
The International Direct Dial (IDD) call right is enabled and the prefix for the IDD service is configured. In addition, the carrier has enabled the international toll call service.
Step 1 Check whether the called number contains prefix 00. For example, number 0086*********** contains prefix 00. If the called number contains the prefix 00, run the config protocol pra officeno x typeofclinumber unknown command to set Type of number to Unknown. In the preceding command, x specifies the route selection number of the PRA trunk.
Step 2 If the called number does not contain the prefix 00, run the config protocol pra officeno x typeofclinumber international command to set Type of number to International.
Step 3 If the fault persists, contact Huawei technical support engineers.
The calling number type under the PRA trunk is incorrectly configured.
