I tried numerous but most of them just don't work. They fail on the quality of the microphone. I tried two that support alsa. Kphone does, but dtmf (the numbers) are not recognized by Asterisk :-( I tried X-lite, but that has really terrible voice quality (mic). I tried Sflphone (has alsa support) and that worked on FC4 (not on FC3) and it does not work on Centos44 either:
[root@raaf ~]# rpm -i sflphone-qt-0.6.2-1.i386.rpm error: Failed dependencies: libstdc++.so.6(GLIBCXX_3.4.4) is needed by sflphone-qt-0.6.2-1.i386 sflphoned is needed by sflphone-qt-0.6.2-1.i386 yum provides libstdc++.so.6

[root@raaf ~]# ll /usr/lib/libstdc++.so.6 lrwxrwxrwx 1 root root 18 Mar 9 05:56 /usr/lib/libstdc++.so.6 -> libstdc++.so.6.0.3
I'm lost. It complains about something missing that is installed??
I try to find a softphone that works with Asterisk and Centos44, does anyone has a good suggestion or is it better to buy a hardphone?
Thanks, Theo

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).
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 (www.vono.net.br), 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.

the output quality of the Intel branded motherboards I've used has been quite good. Microphone inputs somewhat less so, but still plenty good enough for telephony IF your microphone has high enough gain. If someone is recording high fidelity (music, etc) from microphones, I recommend they get an external microphone preamp and use the line input on their sound card, or even better a USB input/output box.
for voice/telephony, USB headsets are the way to go.

I also have one trust USB headset and it works, except the volume cannot be adjusted, it's always max (and that's not nice for a headset...). I have 20 desktops running FC4/Centos44 on AMD based Motherboards. The sound is onboard using a Nvidia chipset. Using skype and esd/arts the sound is very good, no problem. As soon as I try any of the softphones the mic is heavily distorted. I can even hear a hum as if the ground shielding is not properly connected. Since skype works so nice (using eithers OSS or alsa) I expect this to be a software based problem not hardware. And one softphone is working with FC4 (slfphone) but not on Centos4.4. The mic sound is less compared to skype (there is a hiss, when pronouncing the letter 's' the sound is distorted) but upto now that's the only one that is acceptable for only FC4, not Centos :-(

Well I tried Twinkle and it works, but on a scale from 0 to 10 I give the sound a 5 were I can give the Skype sound quality a 9+. Strange that it seems to be so difficult to get good sound quality on Centos/FC. My motherboards are A8N32-SLI Deluxe and Foxconn NF4UK8AA-8EKRS both equipped with onboard Realtek ALC 850. Has anyone experience (good or bad) with the Realtek ALC 850?

Comparing Skype & Twinkle sound quality is not really fair. The reason is that Skype uses 16k samples while SIP clients like Twinkle use the very common 8k samples. Skype will always sound better than standard SIP clients or POTS. The only VoIP solution I know off that has similar sound capabilities is Polycom's latest VoIP phone the IP650. Your VoIP PBX will need to support this too off course or else it will fall back to the plain old sound.

I've had very good sound quality with Skype 3.0 on Windows XP inside VMware with CentOS 5 (beta). I've been using SkypeOut and Vono (similar product, other soft-fone client) inside VMware with impressive quality (wth CentOS 4 it wasn't as good as now).
For Linux soft-fone, I have heard that this one is very good: http://www.sjlabs.com/sjp.html I'll give a try.
