Re: [orca-list] OT Orca, Skype and accessibility workaround

Hi,
Its important to realize that if you're talking about people who use Skype
as a normal PSTN gateway, the quality is horrible. i'll admit that. Now,
if you have two Skype clients (excluding Windows Mobile), the audio
quality is quite good. Monoral, but its all right. I have no idea of what
codec Skype uses. However, what I can tell you is that its adaptive to
network conditions, which I'd almost bet that almost all codecs are these
days. You mentioned FreeSwitch. A search of Debian's unstable packages
doesn't reveal anything, but perhaps noone has decided to package it for
that distro. Wher can I find information about that?
Thanks.
