Check pattern
The
Check pattern
page (
Maintenance > Tools > Check pattern
) allows you to test whether a
pattern or transform you intend to configure on the VCS will have the expected result.
Patterns can be used when configuring:
•
Allow Lists and Deny Lists
, to specify aliases to be included in the list
•
Pre-search transforms
, to specify aliases to be transformed before any searches take place
•
Search rules
to filter searches based on the alias being searched for, and to transform an alias
before the search is sent to that zone
•
Subzone membership rules
to determine, based on the address of the device, to which subzone
an endpoint is assigned when it registers with the VCS
To use this tool:
Alias
Enter the alias against which you will test the transform.
Pattern
In the
Pattern
section, enter the combination of
Pattern type
and
Pattern behavior
for the
Pattern
string
being tested.
•
If you select a
Pattern behavior
of
Replace
, you also need to enter a
Replace
string.
•
If you select a
Pattern behavior
of
Add prefix
or
Add suffix
, you also need to enter an
Additional
text
string to append/prepend to the
Pattern string
.
Click
Check pattern
to test whether the alias matches the pattern.
The
Result
section shows whether the alias matched the pattern, and displays the transformed
alias if appropriate.
The
Locate
page (
Maintenance > Tools > Locate
) lets you test whether the VCS can find an
endpoint identified by a given alias, within a specified number of "hops", without actually placing a
call to that endpoint. The results include the list of zones that were searched, any transforms and
Call Policy that were applied, and if found, the zone in which the alias was located.
This tool is useful when diagnosing dial plan and network deployment issues.
To use this tool:
Alias
Enter the alias you want to locate.
Hop count
Enter the number of hops for the search.
Protocol
The protocol used to initiate the search, either H.323 or SIP. The search may be interworked during
the search process, but the VCS always uses the native protocol first to search those target zones
associated with search rules at the same priority, before searching those zones again using the
alternative protocol.
Source zone
The zone from which to simulate the search request. Choose from the
Default Zone
(an unknown
remote system), the
Local Zone
(a locally registered endpoint) or any other configured neighbor,
traversal client or traversal server zone.
Click
Locate
to start the search. The status bar shows
Searching...
followed by
Search completed
.
The body of the status section then shows whether or not the alias was found, any transforms that
were applied, and the zones that were searched in order of priority.
The
Locate
tool performs the search as though the VCS received a call request from the
selected
Source zone
. For more information, see the
Zone searching and transform process
section.
