If the local NBX system fails to access the remote system, an error
message appears similar to the one shown in Figure 34.
Figure 34
Query Remote Error Message
If you have not yet configured the remote system to support VTLs, this
message indicates that you must do so before the Query Remote
operation can succeed.
If you have configured the remote system to support VTLs, the error
message indicates that the local NBX system cannot access the remote
system using the IP address you specified. To remedy the problem:
1
Verify that you specified the correct IP address for the remote system.
2
Verify that the remote NBX system is running properly.
3
Verify that the remote NBX system is using the dial plan which you
modified to configure VTLs on that system.
4
Work with your network administrator to verify that WAN connection
between the two sites is properly configured and is working.
5
Verify that the VTL extensions are included in the
Devices Using
Pretranslator
table.
Placing Telephone Calls
The final step when verifying a virtual tie line connection is to place
telephone calls in both directions between each pair of connected sites.
