problema con trunk sip

Estimados.
Tengo creado 3 trunk:
zapg0 (por defecto)
4002_sip
4001_sip

El caso es que para diferenciar las llamadas uso los prefijos 4001 y 4002 que son rutas salientes en el fondo.
Al marcar 40020056xxxxxx no tengo problemas la llamada se cursa, no así al Marcar 40010056xxxxxx me indica que el trunk esta ocupado.

Ambos trunk están registrados.

en el CLI me aparece los siguiente:
