Network outage don't bring down layer3 isdn

Hi Everyone,

Just wondering if someone ran through this case over the years...

Scenario :

2 routers in mgcp with 1 T1 on each.  The DMS switch cascade the calls to the second T1 if the first one fail.

In a case you lose network connectivity on the first router, thus having the mgcp in a down state the calls should go to the second T1 but having mgcp down doesn't bring down the layer3 on the isdn link... I still ses the isdn status as MULTIFRAME ESTABLISHED...

I tried the busyout command but this only put channels in a busy state ... the first T1 still receive the incomming calls thus not cascading...

Anyone have an idea of what I could do to make the isdn link go down when the mgcp go dwon as well ?
