Operational logic

Redirect Server:

When an INVITE is received, the Public Address is extracted from the
request URI.

For example:
INVITE SIP/2.0

When the SIP Redirect Server searches the location database, it tries to
find all the endpoints that meet the following requirements:

— The endpoint belongs to the specified domain.

— The endpoint has associated routing entries (with both of the

following) :

exact phone-context as the one received

longest DN-prefix that prefixes the received DN

Table 3 "Search results of location database" (page 97)
