ISDN problem

HI all,

i have a problem with ISDN timeout on a VIC-2B-NT/TE and a 1751V.

I'm using the router as a voip / ISDN gateway, with ISDN setup in network mode.
Everithing is working fine except when i try to simulate a problem on NT network.
If i connect my ISDN phone on the router with correct MSN my phone work well (ringing, answer voice hangup etc...) but when i place the wrong one the phone correctly doesn't ring but the cisco router stuck.
The B-Chan where the router place the call is marked as used, with ISDN status i see the B-chan allocated with a CCB:

ISDN BRI1/1 interface
        ******* Network side configuration *******
        dsl 1, interface ISDN Switchtype = basic-net3
    Layer 1 Status:
        ACTIVE
    Layer 2 Status:
        Layer 2 NOT Activated
    Layer 3 Status:
        0 Active Layer 3 Call(s)
        CCB:callid=8038, sapi=0, ces=1, B-chan=1, calltype=VOICE
    Active dsl 1 CCBs = 1
    The Free Channel Mask:  0x80000002
    Total Allocated ISDN CCBs = 1


this stay pending until i shutdown the bri interface.
On SIP server last message is a SIP 100 Try and no more.
It' seems that router wait forever for an answer on B-CHAN and
no timeout is coming.
This problem generically happen when Layer 1 Status is ACTIVE and there is no ISDN TE equipment that can answer the call.
I try to set up every isdn timers with no results.
This is my configuration:
