Cannot connect Moto X Play to JIB Skullcandy wireless for calls

A

AC Question

The Bluetooth earphones (JIB Skullcandy) are working well with my Samsung J5 and Dell Latitude laptop, and working well for all media for my Moto X Play. However, the option in bluetooth settings for "Phone Audio" is not getting checked. It just won't!
And initially when I connected and it got checked by default, I could not hear the call audio. It was all disturbance (zzzzz...). So sometimes it won't get connected, and if it will I will hear disturbance.
Please help.
