though telegram is a great and reliable communication tool, I wouldn`t have a negative view on it only that is developers need to work on video conferencing tool, and help make the audio more clearer, the app could be of more advantage if it could send notification to a cellphone via text when a person is not connected to the internet and has a message sent to their telegram account
