<DIV> 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. </DIV>
<DIV>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.</DIV>
<DIV>Has any friend knows the reasons for that? </DIV>
