call is not routed to a trunk. For transferred calls or calls to an ICD Group, if the DISA port has become
unavailable when the trunk-to-trunk conversation is actually established, the call is established without
DISA.
When using this feature, the Trunk-to-Trunk Call Limitation timer should be enabled. In addition, prolonging
the call through DTMF signalling is not available.
