I actually love the call quality of mine, again unless the tests are done over the same network, the call quality is going to vary from location to location because a lot of it depends on call connection and like hundreds of other factors.
I "temporarily" switched from N8 to Omnia 7 I got for free just to get used to WP before I get a 920 and wow, never in my life have people complained about not hearing and understanding me over the phone. I've always used Nokias, but empiric results show that 10 year old Nokias do better in call quality than Samsung Omnia 7 :D
I've had fantastic call quality on my 920 so far. I've only made 2 or 3 calls so far, but I've been able to hear the other person wonderfully and they have been able to hear me great too. Definitely way better then my old phone.
Excellent call quality for me too... As others have mentioned it is actually at "landline quality" for me. If your phone consistently has a buzzing sound during calls then maybe you have a bad speaker.
I am having the SAME problem. I went to 2 ATT stores and they both told me that it was the speaker that was blow. I have the Cyan (honestly, I was excited to get it but im glad this happened b/c im not really a fan) and they were going to charge a $35 restocking fee to give me black. Called ATT premiere and they are giving me a $50 credit to trade it out for a black.
UPDATE- Went in and got the Black one and everything works great. If your having this problem you should go to ATT and see what they can do.

If you're having issues with call quality, exchange the phone. This was an issue with some early 900s as well. My father had to exchange his twice before he got one with no buzz or echo... luck of the draw sometimes. Mine sounds absolutely clear as a bell, like a Nokia should.
Day 2 with my 920, and 5 people I have talked to complained about not being able to hear me clearly, but when I call from sister's iPhone 5 there is no problem. I am going to have at&t give me another 920 today.
If there is a buzzing, I would say there is something wrong with your phone. Call quality is definitely not something I can complain about with this handset. While I wouldn't say my standards are sky high, there is definitely no distortion experienced on either my end or the other.
