Timeout lors du ringing

**tshup** · 28/05/2013, 09h56

Bonjour à tous,

Je rencontre un petit souci lors d'un Dial depuis un serveur asterisk vers un trunk SIP (type completel mais également cisco), la sonnerie s'arrête après environ 30 secondes, indépendamment du timeout spécifié. (Si le timeout est inférieur à 30 sec, la sonnerie s'arrête bien au temps désiré, mais ne dépasse jamais les 30 sec).

J'ai lu ici et là qu'il s'agissait d'un problème de NAT, mais je n'ai pas trouvé (ou compris

) de solutions. Je passe par un proxy SIP Kamailio. J'utilise la version d'Asterisk 1.8.17.0 que j'ai installé classiquement depuis les sources.

J'ai fait un debug SIP :
