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 at 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 libstdc++.i386 3.4.6-3.1 installed Matched from: /usr/lib/libstdc++.so.6 [root at 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
