asterisk users - Feb 2008 - Can asterisk support 20 user's conference?

HI, Friends,
         Now I have 20 polycom?s SS2 phones. Can Asterisk support 20 users
conference meeting? And I want to build HD audio conference by using polycom?s
650 ip phone. Can asterisk support G722 HD audio conference? Any friend can help
me? Thanks

Whichever codec you use, asterisk needs to be able to transcode to slin
so that the channels can be mixed (and back again).

Since only Asterisk 1.6.x comes shipped with a G.722 codec, then you are
restricted to using this. (there isn't a stable release from 1.6.x yet).

Dependant on hardware, asterisk should be able to support 20 users in a
conference. I've used Page(<phones>,d) with lots of phones before, and
it seems to work. (creates a dynamic conference with listed phones in it).

Yes.

Afaik Asterisk only supports it in 1.6beta. If you need a working
solution *now* then have a look at FreeSWITCH which supports wideband
and ultra-wideband conferences very well.
