hmm...
I have adsl to internet and this is the connection I use for tests.
I haven't yet set up QoS as I am testing on clear connection.
And while using for ex. MS Portrait (ueee MS but this is a piece of cool
soft)
for talking with friends via internet I get the quality much better than
that of asterisk,
what is the reason. In both cases there is GSM06.10 codec used.

Can anyone tell me which codecs I could use (are bulit into) with asterisk
h323 channel?

Thanks,
BR,
KRiz
