Dial plan and call processing
Field Description
Priority The order in the search process that this rule is
applied, when compared to the priority of the
other search rules. All Priority 1 search rules
are applied first, followed by all Priority 2 search
rules, and so on. More than one rule can be
assigned the same priority, in which case any
matching target zones are queried
simultaneously. The default is 100.
Protocol The source protocol for which the rule applies.
The options are Any, H.323 or SIP.
Source The sources of the requests for which this rule
applies.
Any: locally registered devices, neighbor or
traversal zones, and any non-registered
devices.
All zones: locally registered devices plus
neighbor or traversal zones.
Local Zone: locally registered devices only.
Named: a specific source zone or subzone for
which the rule applies.
Source name The specific source zone or subzone for which
the rule applies. Choose from the Default Zone,
Default Subzone or any other configured zone
or subzone.
Request Specifies whether the search rule applies only to
must be authenticated search requests.
authenticated
Mode The method used to test if the alias applies to
the search rule.
Alias pattern match: the alias must match the
specified Pattern type and Pattern string.
Any alias: any alias (providing it is not an IP
address) is allowed.
Any IP Address: the alias must be an IP
address.
Pattern type How the Pattern string must match the alias for
the rule to be applied. Options are:
Exact: the entire string must exactly match the
alias character for character.
Prefix: the string must appear at the beginning
of the alias.
Suffix: the string must appear at the end of the
alias.
Regex: treats the string as a

Usage tips
The default configuration means that the Local
Zone is searched first for all aliases. If the alias
is not found locally, all neighbor, traversal
client and traversal server zones are
searched, and if they cannot locate the alias
the request is sent to any DNS and ENUM
zones.
Named sources creates the ability for search
rules to be applied as dial plan policy for
specific subzones and zones.
Only applies if the Source is set to Named.
This can be used in conjunction with the VCS's
Authentication Policy
available to unauthenticated devices.
Applies only if the Mode is Alias Pattern
Match.
You can test whether a pattern matches a
particular alias and is transformed in the
expected way by using the
tool (Maintenance > Tools > Check
