487%

487% is the average number of SIP 487 responses compared to all call attempts.

A SIP 487 Request Terminated response indicates that the call request has been canceled by the originator. Here are some common causes for receiving a SIP 487 response:

1. User Cancelled the Call: The called party manually ended the call before it was fully established.

2. Network Congestion: High network traffic or congestion can cause the call to be terminated.

3. Codec Mismatch: Incompatibility between the codecs used by the caller and the recipient can lead to call termination.

4. Insufficient Resources: The recipient's system might not have enough resources (e.g., bandwidth, processing power) to handle the call.

5. High Post-Dial Delay (PDD): If there is a significant delay in hearing the dial tone, users might cancel the call.

6. Interactive Voice Response (IVR): Users might hang up if they hear an IVR recording and decide not to proceed with the call.

7. Routing Issues: Problems with the call routing path can result in the call being terminated.

The 487% of call attempts can be found in the Hour Destination and LATA OCN reports in the Service Provider platform.
