Operational logic

The following items describe the operational logic of the CS 1000 SIP

Redirect Server:

•When an INVITE is received, the Public Address is extracted from the

request URI.

For example:

INVITE <sip:dn;phone-context=pc@domain;user=phone> 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

Table3 "Search results of location database" (page 97) shows the

possible outcomes of the location database search.
