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 transform
•
s
, to specify aliases to be transformed before they are searched for locally
Local Zone matche
•
s
and
zone matches
, to filter searches based on the alias being searched for,
and to transform an alias before the search is executed to that zone.
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
Behavior
for the pattern being
tested. If you have selected a
Behavior
of
Replace
, you will also need to enter a
Replace
string.
Check pattern
Click here to test whether the alias matches the pattern.
The
Result
section will show whether the alias matched the pattern, and if so, the resulting
transformed alias.
The
Locate
page (
Maintenance > Tools > Locate
) allows you to 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 will 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 wish to locate.
Hop count
Enter the number of hops for the search.
Protocol
Select whether the search will be initiated using H.323 or SIP. The search may be interworked
during the search process, but the VCS will always search all zones at a given priority using the
native protocol first, before searching those zones again using the alternative protocol.
Locate
To initiate the search, click
Locate
.
The status bar will show
Searching...
followed by
Search completed
. The body of the status section
will show whether or not the alias was found, any transforms that were applied, and the zones that
were searched in order of priority.
When searching for an alias, the VCS will first search all the highest-priority zones using the
protocol of the incoming call. If the search was unsuccessful the VCS may then search the
same zones again using the alternative protocol, depending on where the search came from
and the
Interworking mode
(
VCS configuration > Protocols > Interworking
), If this search is
unsuccessful, the VCS will then move on to the next highest priority zones, first searching in the
native protocol and then in the alternative protocol.
The
Locate
tool initiates a search as though the VCS received a call request from a remote system,
rather than a locally registered endpoint. Therefore if
interworking mode
is set to
Registered only
,
the VCS will search the Local Zone using both protocols, and all other zones using the native
protocol only (because it will interwork the call only if one of the endpoints is locally registered).
If
interworking mode
is set to
On
, the VCS will search the Local Zone and all external zones using
both protocols.
