Doesn't foward my calls anymore.

[AC Question]

I bought i7+ few days back and bought a jio sim aswell. I had my redmi note 3 earlier so i inserted my jio sim in i7 and my older sim in note3 and activated foward calls from note 3 to i7. 2 days it worked great but after that it just cancel my call from any number but i do get a notification on my i7 (truecaller app) that this person just called you but I actually never get the call.
What to do? Help!

Mayby it's some settings parameters in menu of phone ?
