At least the ioBroker can make a Telegram phone calls (with Voice) too thanks to the CallMeBot API. You need ioBroker.telegram adapter with version >= 1.5.0 for that.

Everything is you need is to create a blockly or script as following:

Blockly

Just place the block "call via Telegram" as on the picture:

xmlns="http://www.w3.org/1999/xhtml" type="on" id="pcI%RNejJ#^wD#ZBKcPV" x="62.800048828125" y="37.399993896484375">
  name="OID">javascript.0.trigger
  name="CONDITION">any
  name="ACK_CONDITION">false
  name="STATEMENT">
    type="telegram_call" id="D==]%~cRa3pHO99!P4Qs">
      name="INSTANCE">
      name="LANGUAGE">
      name="LOG">
      name="MESSAGE">
        type="text" id="o$5h,J65nfBdfVO.3|fd">
          name="TEXT">ioBroker is calling you!
       
     
      name="USERNAME">
        type="text" id="V/Gwj;1y%D@`xq9*#niO">
          name="TEXT">@Username!
       
     
   
 

and set the valid MESSAGE and USERNAME.

Now by change of the state trigger the call via telegram will be done.

Script

To use calls via Telegram in script write following:

sendTo('telegram.0','call','Some text');

or 

sendTo('telegram.0','call', {
    text: 'Some text',
    user: '@Username',
    language: 'de-DE-Standard-A' // optional
});

Problems?

If you have problems, like not receiving the Call on Telegram, or not receiving the WhatsApp messages,  try to test the CallMeBot API using your Web Browser:

  • Telegram Phone Calls using Web Browser: here
  • Telegram Text Messages using Web Browsers: here
  • WhatsApp Text Messages using Web Browser: here

You might get some errors on the screen that will help you to identify the problem. (Ex: Calls disabled in the Telegram Security Settings, WhatsApp not activated, etc.)

If you still have problems to use this API, don’t hesitate to contact me in Telegram @callmebot_com or by email at support@callmebot.com. Rember to Follow me on Twitter to get news about coming features, changes, invitations, etc.
