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).
The first search rule takes any aliases in the format string@domain and transforms them into the
n
format string.
To ensure that any endpoints that have actually registered with an alias in the format
n
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.
