lost iphone at home

I lost my iphone at home in some place, as "find iphone" function showed that my iphone is at home. As I try to call my iphone from my landline phone, the ring tone came out of my macbook pro and not from my iphone. In an attempt to disconnect my iphone from icloud, so that I can hear the ring sound coming from my iphone, I erased the iphone from icloud.

Now there is no sound whatsoever, neither coming from my macbook pro nor from my iphone, even though I know the iphone is somewhere in house.

Could someone helps me finding my iphone ?

Many thanks in advance.
