What is isdnBearerOperStatus?

Read-only current call state of this B channel: idle(1) means no call is active, connecting(2) means an outgoing call is being placed, connected(3) means an incoming call is being validated, and active(4) means a call is actually up - useful for spotting a channel stuck mid-setup.
