J'ai redéfini encore mon adresse ip en static sur le serveur Asterisk et Bridgé le paramètre réseau de VMWare.

Et ça fonctionne maintenant.

Code:
IPBX-Asterisk*CLI> pjsip show registrations

 <Registration/ServerURI..............................>  <Auth..........>  <Status.......>
==========================================================================================

 belgium-voip/sip:voip.belgium-voip.com:5060             belgium-voip-auth  Registered
 selfone-voip/sip:sip.cmrp.net:5060                      selfone-voip-auth  Registered

Les pings vers les noms de domaines des providers fonctionnent de nouveau :
