Error Message
Invalid parameter value.
Description
Incorrect parameter settings.
Possible Cause
1. The number of parameters is incorrect. For example, mandatory parameters are not passed.
2. The call status is incorrect. The most common error is that an outgoing call fails to be reported as its status is not VOIP_CALL_STATE_DIALING.
3. The call type is incorrect. Currently, only the voice call VOIP_CALL_VOICE and video call VOIP_CALL_VIDEO are supported.
4. The call ID does not match the call. For example, when a call status change or audio status change is reported, if the passed call ID cannot be found in the call record, the call fails to be reported.
5. The call is repeatedly reported. For example, if an outgoing call is reported twice, the second report fails.
Solution
1. Ensure that the preceding parameters are correctly passed.
