[cisco-voip] E1/T1 CAS Trunk group issue

[Chris Osborne (US)]

Has anyone run into placing two T1/E1 CAS circuits into a trunk group on a cisco router and the trunk group not function properly when the T1/E1 is completely down ?

I'm noticing even if the circuit is disconnected physically from the router the trunk group still thinks the circuit up and routes the call over to it. I have  a TAC case open but they are still working on it. I've never seen this with a ISDN PRI trunk group.
