can't call an extension

Hi Experts,

I have 3 Trixboxes version 2.2.4 and 2.6.
the 3 boxes are connected through Dundi.
everything works fine between each boxes but for some reason I can dial an extension from one of my box:
T1 can't call 588 on T3
but T2 can call 588 on T3
T1 can call all other extensions on T1 or T3
the outbound route has the extension properly configure on T1 but everytime that we try to call from any extension I get "all circuit are busy"
attach is the log from my extension 534 trying to reach 588
Please any help would be appreciate:
