Hi,

On a 5350 i'm trying to find a way to make the isdn channels of a pri seem busy, when they get free.

I've found the following, but i don't want to make all of them busy; just the free ones. And as soon as a channel gets free, i 
want it to be blocked automatically.

5350(config-if)#isdn busy ?
   b_channel  Specify the B-channel or range of B-channels, 0 for the complete interface.
   dsl        Specify the DSL value (DEPRECATED).

dial-ath-24(config-if)#isdn service b_channel 0 state ?
   <0-2>  Valid states are 0=Inservice 1=Maint 2=Outofservice



In other words, i want to block the isdn channels, but not disconnect the current users. So after some days, all channels will be 
blocked and i will be able to do maintenance on the router without affecting anyone.
