tu reçois un OK, pour un INVITE, no de sequence 103 (Cseq 103). tu l'acquittes, c'est bien. Mais OVH renvoie le paquet un certain nombre de fois, avec le même no de séquence.
Donc, cela veut dire que le paquet ACK n'arrive jamais sur le serveur OVH, qu'il réement le OK un certain nombre de fois, puis coupe la comm.
Pourquoi.... mystère et boules de gomme !!
Autre truc bizarre, sur le dernier post (le #19), le message OPTION vient du port 5062, puis le reste du dialogue sur le port 5060....
Seul point à vérifier, n'aurais tu pas la fonction SIP ALG activée sur ton routeur ?
