Both ends need to support wideband codecs, as does your phone (hard or soft phone). This includes the VOIP providers needing to be able to use wideband codecs between each other.
If you achieve a wideband setup the call quality is amazing. I've used it for years. It really sucks when you have to call someone on a legacy POTS line or using a narrow band codec (bad voip, cell phones, etc)
On that note it's unfortunate that cell phones which can do wideband codecs within the same carrier (HD Voice!) won't work if your call leaves their network.

This is quite annoying, but it's because the PSTN overall is stuck on G.711 and G.729 - my SIP provider doesn't support anything else because they would be forced to re-encode the signal anyway and lose quality doing so. Ultimately, we need to be putting pressure on the telco's to enable support for G.722 - until that happens we're going to be stuck with 4KHz audio for a long, long time.
