For caller:

1. When the other side is having an imo call 

and rejects your call, it shows 'Busy'.

2. If you can not receive a 'Busy' notice, did you

cut the call at your side?

   If the other side did not accept/reject your call, 

it may show 'Busy' after a few minutes (within 5 

minutes).  

If the problem still keeps unsolved, you may 

send us a feedback and mention "The caller 

side missed the 'Busy' notice".

We will optimize the feature and provide more 

optional notices like "I am busy. Pls call me 

later". Please stay tuned!
