 ## Phone calls
 _Supported on:_ :material-android: :material-apple: :material-firefox:
 
-You can use ntfy to call a phone and **read the message out loud using text-to-speech**, by specifying a phone number a header. 
+You can use ntfy to call a phone and **read the message out loud using text-to-speech**. 
 Similar to email notifications, this can be useful to blast-notify yourself on all possible channels, or to notify people that do not have 
 the ntfy app installed on their phone.
 
-Phone numbers have to be previously verified (via the web app). To forward a message as a voice call, pass a phone number
-in the `X-Call` header (or its alias: `Call`), prefixed with a plus sign and the country code, e.g. `+12223334444`. You may
-also simply pass `yes` as a value if you only have one verified phone number.
+**Phone numbers have to be previously verified** (via the web app), so this feature is **only available to authenticated users**. 
+To forward a message as a voice call, pass a phone number in the `X-Call` header (or its alias: `Call`), prefixed with a

+verified phone numbers.

+!!! info
+    As of today, the text-to-speed voice used will only support English. If there is demand for other languages, we'll
+    be happy to add support for that. Please [open an issue on GitHub](https://github.com/binwiederhier/ntfy/issues).
 
 On ntfy.sh, this feature is only supported to [ntfy Pro](https://ntfy.sh/app) plans.
