App crashes when I try to call contacts

Expected behavior

When I enter the contact chat, I am supposed to be able to use the call button in the private chat to call the contact.

Actual behavior

Instead of being able to use the call button on the chat, it crashes when you press the button and automatically stops working.

How to reproduce

Go to Google Playstore, download Kontalk and install, register and when done, click the pencil button and start new chat, you will see a number or two, click anyone ,enter the chat, on your top right you will see a three dotted icon, click and you will see call, click call and the app will crash.

• Browser: Kontalk
• Operating system: android 7.0 ,tecno Camon cx air.
