These search rules ensure that both the E.164 number and full URI are searched for, so that endpoints can
still be reached whether they have registered with an H.323 ID (123abc) or a full URI (123abc@domain).
n The first search rule takes any aliases in the format string@domain and transforms them into the format
string.
n To ensure that any endpoints that have actually registered with an alias in the format string@domain can
also still be reached, the lower-priority second search rule places calls to string@domain without
transforming the alias.
Allowing calls to IP addresses only if they come from known
zones
In addition to making calls to aliases, calls can be made to specified IP addresses. To pass on such calls to
the appropriate target zones you must set up search rules with a Mode of Any IP address. To provide extra
security you can set the rule's Source option to All zones. This means that the query is only sent to the
target zone if it originated from any configured zone or the Local Zone.
To achieve the example described above, from the Create search rule page (Configuration > Dial plan >
Search rules > New) set up a search rule as follows:
Field Value
Rule name IP addresses from known zones
Description Allow calls to IP addresses only from a known zone
Priority 100
Source All zones
Request must be
authenticated
No
Mode Any IP address
On successful match Continue
Target zone Overseas office
