Sip Fax lot of error

[jayse]

Bonjour

J'utilise Asterisk pour envoyer et recevoir des faxs.
La solution marche, mais je rencontre un grand nombre d'erreur :
- (Incoming et outgoing) The call dropped prematurely
- (Incoming et outgoing) Unexpected message received
- (Incoming) Disconnected after permitted retries
- (Outgoing) Invalid response after sending a page

Asterisk 1.6.2.17.2
J'utilise T.38 sur le SIP
Je suis sur un kernel 2.6.18-194.el5 x86_64

Voila ma config

    <------------->

et sur un appel en échec je joinds un fichier de log.

J'ai une autre plate-forme avec un autre trunk_sip
Il y a très peu de différence :
t38pt_udptl=yes,redundancy
sans ,maxdatagram=400
et
allow=alaw,ulaw
et inversement pour l'incoming

Je ne suis pas sur de la configuration des trunks car se ne sont pas les miens
