AFAIK, microphone bad quality is more related to the hardware, not the
software. My onboard "Intel high definition" sound chipset (ICH7
compatible -
Intel 945GNT) has a bad output sound, but a much worse input
(microphone). I have tried using Windows XP, CentOS, Ubuntu, many
softphones
(Skype, X-Lite, Ekiga, Twinkle) and definitely the problem is hardware
(or all drivers are broken).<br>
<br>
The solution was to buy a PCI sound card from a friend (Ensoniq 5880
AudioPCI). Its output quality is not that good - but better than "Intel
high definition" - and its input quality is of a very good usability.
Although it worked very nicely on Ubuntu 6.10, the microphone is not
working on CentOS yet (actually it work once, but I wasn't able to
reproduce yet, maybe I was using Centosplus kernel, don't remember
now), but I'm gonna invest some time on that as soon as I can.

I have used Twinkle on Ubuntu 6.10. Between many free softphones, it
was for sure the best. I have not used it with a personal Asterisk, but
I have used it with a real VoIP company (<a
href="http://www.vono.net.br">
www.vono.net.br</a>), which *may* be using Asterisk. It had some bugs,
needed to be restarted from time to time, although it was far from the
last version. I would really recommend this software, if it was
available as rpm to CentOS.

At last, I can say Skype works on CentOS, though this is not what you
want.<br>

Skype works perfectly with Centos4.4. Microphone sound is HIFI. We use
that up to now in our company together with POTS (ISDN phones). So I
know the sound can work good but for some reason most softphones give a
very jurky sound. I had even installed (old) Nforce drivers from
Nvidia. It didn't work either since we all sounded like Donald Duck
(sound pitch was about twice too fast).<br>
I'll give Twinkle a try. I just compiled it successfully and were able
to run it. Since I work remotely via a vnc session without sound
(that's a pitty...) I'll check the sound quality when I'm in the office
tomorrow.<br>
I found this message at the sound settings of twinkle: "When using
ALSA, it is not recommended to use the default device for the
microphone as it gives poor sound quality". Fine with me, but what is a
better choice then?<br>
<br>
Thanks Leonardo for the tip.<br>
