asterisk users - May 2008 - G.722 for polycom

I have test G.722 for many phones. I have try calls between sip G.722, sip G.722
to sip G.711, G.722 to RRI cards, PRIcards to G.722. I also test meetme
conference. Other phones such as grandstream and fanwei have no problems. The
sounds is good, grandstreams have little difference between G.711 and G.722.
But Polycom's IP 550 have many problems. Polycom's G.722 to TE210E1 have
problems the sound is choppy. Polycom's G.722 to conference also have
problems, I even cannot heard the sounds.
Has any friend knows the reasons for that?

What version of Asterisk are you using?  I have made a lot of G.722 related 
fixes over the last few months.
