I have an ionic 3 app that I created for video conferencing. The problem is if the other party is not online, I can call him. I want to be able to do offline calls wherein if the other party is not online, I can call him and his app will open and display the call just like skype or whatsapp. Can ionic able to do that and if so can someone send me a sample code? If not, what is the workaround?
Thanks in advance
