> See call trace below.  Its a linkset with 2 E1s configured but only 1 E1 connected.  Asterisk receives a call setup (IAM) message from far-end Siemens switch on a CIC that is on the disconnected E1.  Asterisk does not reject the call but signals back to accept the call and continues to setup the call.  Asterisk then procedures to send audio out on that CIC on the down E1.  The logical thing to do is to remove the E1s or have the other side be smarter about requesting call setup on a CIC that itself knows to be down but we have no control of the other side and E1s do go down so we need to be able to reject the call if Asterisk knows about it so at least the other side will reject the call as well.  Right now the call completes ok but with no audio b/c of the obvious wrong CIC.
