Many suppliers are now beginning to offer VoIP products that support wideband speech. The selection of codec will...
likely depend on the target market.
For example, if a company is making a VoIP telephone set for the enterprise that supports wideband speech, it would likely support G.722. If a company is making a mobile phone for the 3G network they would likely want to support G.722.2 and VMR-WB.
Some manufacturers decide to support proprietary codecs for various reasons. For example, Global IP Sound provides the iPCM codec, which it claims will provide better speech quality than G.722.2.
