Zenfone 7 - poor phone call quality

Hi. Having used my new Zenfone 7 device for a few days I immediately notice really bad performance in phone call quality (over gsm only, it works great otherwise - over Skype or WhatsApp voice). As I found out that seems to be the common problem here in Poland across all available carriers and many Z7 users have been reporting this issue. Mobile carriers redirect users to Asus Poland and Asus tech support claim they don't know anything about the issue and if I find my particular device flawed I should send it to them for possible repair.

Can anyone tell me if there's anything that can be done about the issue? Is there any hope?
