ERROR: host_disconnect_ack: Unfound B-channel

Bonjour,

Voila une semaine que j'essaye de monter une liaison isdn sur un routeur bri sans succès. Mon architecture est composé d'une valise fleet 77(inmarsat) et d'un routeur cisco

Voici ma configuration:

Depuis la ligne de commande de mon routeur quand j'active le terminal monitor j'ai ceci:

*Jan 1 03:23:32.187: ISDN BR1/0 Q931: RX <- INFORMATION pd = 8 callref = 0x00
Display i = 0x1801
*Jan 1 03:23:42.187: ISDN BR1/0 Q931: RX <- INFORMATION pd = 8 callref = 0x00
Display i = 0x05011F, 'France Te IOR', 0x0D, 'Ready for call '
*Jan 1 03:23:42.203: ISDN BR1/0 Q931: RX <- INFORMATION pd = 8 callref = 0x00
Display i = '4'
*Jan 1 03:23:42.215: ISDN BR1/0 Q931: RX <- INFORMATION pd = 8 callref = 0x00
Display i = 0x1801

Cependant quand je fais un test d'appel en ligne de commande avec la commande isdn test call interface brI 1/0 002425589180

Cepandant voici le statut de mes interfaces isdn

mon interface est aussi bel et bien activé voici la preuve:

Aujourd'hui la situation est tel que je n'arrive pas à me connecter à internet en utilisant ma liaison cependant mon routeur me remonte bien le nom de mon opérateur alors je veux comprendre. Merci de m'aider
