Bonsoir,
Merci pour la réponse. Si tu me conseil de faire un vpn, c'est qu'il n'y a pas d'autre solution. Car voici ce que j'ai fais mais ca ne fonctionne pas.
Voici le contenu du SCCP.conf

A vérifier, mais il me semble que tout est correcte. Si il faut créer un vpn je veux bien mais je ne sais pas faire donc ton aide me serais utile pour faire ça.
Merci de ton aide, cordialement, JA86.
