problemes renvois appels vers numero exterieur trunk ovh

[latitude05]

bonjour, j'ai un soucis de revois d'appel sur un numero exterieur.

j'ai un trunk ovh avec 2 lignes (j'ai fait les test, 2 entrant, 1 entrant/1sortant ou 2 sortant en même temps, ca fonctionne)

- envois des appels entrant vers un poste interne, je fait *72<num de poste> ...ça fonctionne
- envois d'appels vers un numero externe, je fait *72 <004XXXXXX> ca marche pas (j'ai essayé aussi avec un "follow me" sur le poste idem..)

voilà ce que j'ai dans le CLI au moment de l'appel vers mon num exterieur

je ne comprend pas, j'ai des message de "congestion" comme si la ligne était occupé, hors, non....

si quelqu'un peu m'aider, ca m'énerve de bloquer juste sur un renvois d'appel basic..
