Situation 1: When you try to call your friend, does JusTalk show you about "Other user is busy" on your call interface? It might be because the person has blocked you, you can't get through to him/her.

 

Situation 2: After you open JusTalk, did it show up "Disconnected" prompt on your Calls and Messages screens?

Situation 3: When you try to call your friend, what does it show on your call interface "calling", "ringing", "connecting" or "temporarily unavailable"?

 

If you're facing either situation 2 or situation 3, please go to "Any other questions?" for further help.
