examples(foundational): allow running examples with twilio

 ### Other
 
+- It is now possible to run all (or most) foundational example with multiple
+  transports. By default, they run with P2P (Peer-To-Peer) WebRTC so you can try
+  everything locally. You can also run them with Daily or even with a Twilio
+  phone number.

 - Added foundation examples `07y-interruptible-minimax.py` and
   `07z-interruptible-sarvam.py`to show how to use the `MiniMaxHttpTTSService`
   and `SarvamTTSService`, respectively.

+## Running examples with other transports
+
+It is possible to run most of the examples with other transports such as Twilio or Daily.
+
+### Daily
+
+You need to create a Daily account at https://dashboard.daily.co/u/signup. Once signed up, you can create your own room from the dashboard and set the environment variables `DAILY_SAMPLE_ROOM_URL` and `DAILY_API_KEY`. Alternatively, you can let the example create a room for you (still needs `DAILY_API_KEY` environment variable). Then, start any example with `-t daily`:
+
+```bash
+python 07-interruptible.py -t daily
+```
+
+### Twilio
+
+It is also possible to run the example through a Twilio phone number. You will
+need to setup a few things:
+
+1. Install and run [ngrok](https://ngrok.com/download).
+
+  ```bash
+  ngrok http 7860
+  ```
+
+2. Configure your Twilio phone number. One way is to setup a TwiML app and set the request URL to the ngrok URL from step (1). Then, set your phone number to use the new TwiML app.
+
+Then, run the example with:
+
+```bash
+python 07-interruptible.py -t twilio -x NGROK_HOST_NAME (no protocol)
+```
