asterisk users - Feb 2005 - high-quality, high-bandwidth codecs?

hi

are there any codecs around that allows high quality as in "studio 
lite"? it may consume high bandwidth, and hopefully allow some packet 
loss.

I'm not sure what "studio lite" means to you. Maybe hard figures
would
be more precise.

G.722 might be interesting : 64 kbps, 7 kHz. It's not free.

Otherwise, MP3 or OGG might be ok ?

Hi,

   Regarding these high bandwidth CODECs - is it possible to upgrade 
asterisk to record at a higher quality bit rate too - is Asterisk based 
on a 8Khz system. We would like to stream calls from SIP phones to the 
internet at a higher quality than a standard phone, also it would be 
great to build an audio experience that sounds as good as Skype.

   At the moment my VoIP system is considered to offer a lower quality 
call experience than a standard phone ( I am sure it is my equipment 
and configs that is the culprit) - I would love to demonstrate what is 
possible with audio > 8khz

Yes, with development.

Yes, presently.

This presumes you have some kind of sip phone that samples higher than 
8khz..
