Perte enregistrement de téléphone

[tanguyd]

Bonjour

J'ai un asterisk sur un vps et des téléphones dans plusieurs endroits.

Depuis vendredi soir, sans changement connu, les téléphones d'un des sites se déconnectent pendant 3 minutes après avoir été enregistrés pendant une heure.

Je précise que je n'ai pas pour le moment pas la main sur la conf téléphone/routeurs coté client ( j’espère que je pourrais l'avoir demain ). Le routeur est une livebox pro et SIP ALG est actif ( il ne m'a pas posé de problèmes jusqu’à présent )

Avez vous cependant une idée de se qui peut se passer ?

[tanguyd]

Je n'ai pas encore le fin mot de l'histoire, mais visiblement il y aurait des soucis avec la livebox du client, même des services de base tel "dhcp" poseraient problème.
