Default [Q] sound options in moto e

Hi
I have both moto e and moto g
In moto e, when I receive a call, the ringtone starts at a lower volume and then ascends in volume. Also the volume is not as loud as compared to moto g with similar setting.
I'm using inbuilt ringtone - moto in both phones.
My doubt is whether it is normal in moto e to have low volumes. Also, is there a way to remove ascending volumes, and instead make the ringing at high volumes from the start of the call.
Thanks
