# Validate connectivity to Connect Customer with the Endpoint Test Utility
<a name="check-connectivity-tool"></a>

To validate connectivity to Connect Customer, or when your agents are experiencing problems with the Contact Control Panel (CCP), we recommend using the [Connect Customer Endpoint Test Utility](https://tools.connect.aws/endpoint-test/). 

The Connect Customer Endpoint Test Utility performs the following checks: 
+ Validates that the browser being used supports WebRTC.
+ Determines if the browser has appropriate access to media devices (microphone, speakers, etc).
+ Performs latency tests for all active Connect Customer Regions.
+ Performs latency tests to a specific Connect Customer instance, if provided.
+ Validates network connectivity across required ports for media streams.

The complete results are available for download as a JSON file. You can copy the results to include in a support ticket. You can also load the results file into the tool by selecting the **Load previous results** option. This option displays the contents of the file visually and makes it easier to analyze the results. Additionally, you can download a bookmark specifically for the provided instance to make future tests easier to run.
