[cisco-voip] Unity Connection 8.5 and G.722

According to the 8xcucdg.pdf (design guide for 8.x)...

Supported recording Codecs:

PCM linear
G.711 mu-law (default)
G.711 a-law
G.729b
G.726
GSM 6.10

So although it advertises G.722...it doesn't store it in G.722. You must choose 
what codec is used for storage.

PCM has the best audio quality but it'll eat your HDD for lunch if you have a 
voicemail heavy environment.

Can Unity Connection 8.5 take calls in both G.722 and G.711? (the data sheets 
says G.722 is supported) What does it store the message as if you call in with 
G.722 from a 7945? I don’t want any transcoding going on, so I’m assuming in 
software it does some internal transcoding?
 
Or is it like Unity or UCCX where during setup you have to specify 1 and only 1 
codec ? or is it like a phone where it has a list of codecs advertised?
