Dialed number gets busy tone

Possible problem
The target line that the incoming digits map onto is busy, and
there is no prime telephone for the incoming trunk.
Solution
For maximum call coverage, make sure that you configure a
prime telephone for every incoming trunk.

Dialed number does not get through

Possible problem
The digits sent by a switch at a central office or in the private
network did not match any Received number, the Auto DN, or
the DISA DN. There is also no prime telephone assigned for
the incoming trunk. In this case, the caller may hear overflow
tone from the Norstar system or a recorded message from the
originating switch.
Solution
1. Configure a prime telephone for every incoming trunk.
2. Verify that the switch is sending the correct number of
digits for the Received number length defined in your
system.
3. Verify all the digit strings that the switch should be
sending.
