When making a call, can't hear calling unless on speaker, also, i dont have SMMI Test

Like i said in the title, i cant hear the dial tone when making a call(unless on the speaker), if the person im calling answer the call, i cant hear him, if its me answering the call, the other person cant hear me neither. I tried to use the SMMI Test to see if it was a hardware problem, but when i use the code on the calculator nothing happens, also i tried safe mode to see if it was a software problem but the problem remains. It's the Asus Zenfone 2 ZE551ML if it matters.
