Second Call for DID/DISA/DIL/E&M Override
Turn off or on the extension ability to receive a
second call from a DID, DISA, DIL, or tie line
caller.
With this option set to 1, the
destination extension must be busy for a
second DNIS caller to ring through. If the
destination extension does not have a trunk
or CAP key available for the second call
and a previous call is ringing the extension
but has not yet been answered, the second
caller hears busy regardless of this
program setting.
