Device name: Moto G5s plus

Just bought a new Moto G5s plus in India and found a problem in calling App of the mobile.
If we dial a number more than of 10 digit (Ex: 919876543210), the mobile phone connect the call with the mobile number of first 10 digit, instead of giving error for wrong number.
Ex: For 919876543210 it connect the call with user having number 9198765432. Which is wrong, as 91 is india code and it must be skipped OR a error message must be there.
 
Call is a basic functionality of a Mobile phone, and having a issue in that is very critical/serious.
 
Consider a scenario where person want to make ISD call, then he need to pre-fix country code in number. Because of this issue ISD call will not be able to connect.
 
This bug tried on Android 7.1.1 and 8.0
Kindly solve this issue.

Thanks,
