How much bandwidth does the Soundpoint Ip335 require to deliver HD Voice and how does this compare to the none HD voice IP321?

Pete,

 

By my mind there is no difference in bandwidth requirement. The difference is that IP 321 supports G.711 (3.5 kHz within 64 kbps) while IP 335 supports G.722 (7 kHz within the same 64 kbps) in addition to G.711.  The other supported codecs (G.729 and iLBC) are not HD.
