[Ekiga-list] audio problem

[Matthieu LAURENT]

Hi,
I have just installed on my 2 linux pc ekiga and created SIP accounts.
If I call 501 at ekiga.net I ear well the automatic audio conversation.
If I call my other pc (logged with the other ekiga acocunt), I success
in establishing connexion with it, chatting (writting text), but we can
not ear us each other.
If I blow in my microphone I ear white noise so my microphone is well
plugged.
Do you know what kind of problem I may have?
thanks for your help

Matthieu
