Has this been a problem since day one of using your new phone? Or has it developed at some stage since? That would be the acid test of whether the phone is at fault.
You mention outgoing audio dropping - is this a permanent thing, i.e. when it drops during a call, it never returns regardless of how long the call is left open for? Or does it come and go? Does it happen in one specific location, or is it more generalised? And are you saying that it happens across mobile-based calls & WiFi-calling?
Can you use mobile data whilst on a call?
