mulaw is named PCMU in ekiga?

Is that make sense


 There is another problem. The flux (payload) on eth0 is at the beginning not 
zero, but then it rapidly becomes zero byte/second so that I expect that 
absolutly nothing else is transmitted.

I observed 2 cases. 
1) the transmitted bytes (me>ekiga.net) becomes zero before the end of the 
woman blablabla and then the received bytes/ (ekiga>me) becomes zero too
2) Both  transmitted and received bytes fluxes becomes zero when the woman 
ends up her blablabla

Here is a snapshot with gkrellm2 showing case 1 :
http://emmanuelfavrenicolin.free.fr/Public/Divers/Snapshots1/20071120_pb_ekiga.jpg

In grkellm2 window, you can see eth0 received bytes (top and invertted)  and 
transmitted bytes (bottom).  Received bytes stops when the woman stops 
speaking and transmittes bytes stops earlier but the levelmeter of the mic 
continues ocsillating (I connect the radio with a jack connector)

When in preference>audio devices, when I click on "Detect devices", it does 
return this kind of things :
