I suppose you use the _crypted_ password for your account.

Can you try this additional config:
In Preferences → SIP parameters→ Outbound Proxy
213.91.9.206 ( sipproxy.wengo.fr )
or
213.91.9.210
or
213.91.9.216

Maybe, try to deactivate the iLBC codec too.

Don't use the outbound proxy with ekiga.net
Echo test is sip:500 ekiga net
