Call to Non-Local Extension: Warble Tone (Error Tone)
For the call to go through, the extension FRL must be equal to or greater than at
least one of the route FRLs for the pattern that is programmed to reach the
destination extension range.
If it is appropriate to change the extension FRL, see "ARS
Restriction Levels for Extensions" in Chapter 4 of System
Programming.
If you change one or more route FRLs, the modification may
restrict or unrestrict calling from some private network extensions.
Be sure to clear any changes with the coordinating system
manager for the private network. If you decide to make this
change, see "Uniform Dial Plan Routing" on page 5–19 or "UDP
Routing" in Chapter 4 of System Programming. For details about
FRLs in private networks, see "Facility Restriction Levels and
Remote Access" on page 4–5.
If a local extension or route FRL is not the problem, the
coordinating system manager must determine the private
network route for the call once it leaves your local system. If there
is an intervening system between yours and the destination,
proceed to Possible Cause 5.
If there is no intervening system between yours and the
destination, go to Possible Cause 5.
Possible Cause 5:The FRL for the default COR for non-tie trunks (PRI) on the
remote system may be blocking tandem calls. The private network is an all PRI
network.
What to Do: Check with the coordinating system manager so that he or she can
determine where the problem exists. This may involve more than one system,
depending upon how your private network is set up. For example, a call might
be routed across the private network in a fashion such as this:
Origin System A
In this configuration, the coordinating system manager must check routes and
default COR attributes for Systems B and C.
