Tried g722 today for the first time and I am impressed with it. (Until today I've been mostly using alaw. The difference in quality is astounding.)

Not many ATAs seem to support g722, whereas linphone, zoiper etc do support it. Is this due to a reason? (perhaps analog phones cannot work with wideband codecs so ATA manufacturers did not bother to support wideband codecs?) Can someone please clarify?
Thanks in advance!
