the incoming digits onto the Auto DN.
Solution

sending.
2. Check that you have defined the corresponding Received
number for every target line in your system.
3. Check that you have defined the correct Auto DN for your
system.
4. Make sure that the published telephone numbers for your
network are correct.

Dialed number gets busy tone

Possible problem

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.
