 ## Usage
 
 To start a call, simply make a call to your configured Twilio phone number. The webhook URL will direct the call to your FastAPI application, which will handle it accordingly.
+
+## Testing
+
+It is also possible to automatically test the server without making phone calls by using a software client.
+
+First, update `templates/streams.xml` to point to your server's websocket endpoint. For example:
+
+```
+<?xml version="1.0" encoding="UTF-8"?>
+<Response>
+  <Connect>
+    <Stream url="ws://localhost:8765/ws"></Stream>
+  </Connect>
+  <Pause length="40"/>
+</Response>
+```
+
+Then, start the server with `-t` to indicate we are testing:
+
+```sh
+# Make sure you’re in the project directory and your virtual environment is activated
+python server.py -t
+```
+
+Finally, just point the client to the server's URL:
+
+```sh
+python client.py -u http://localhost:8765 -c 2
+```
+
+where `-c` allows you to create multiple concurrent clients.
