Routing using Registrations Database
Typically, routing using the registration database, is applicable to all method types
other than registrations. To route to a registered user (using the internal dynamic
database) an IP-to-IP routing rule must be configured with the desired input
parameters (matching characteristics) and the destination type as IP Group (operation
rule). The destination IP Group must be of type USER.
To find a match for these specific rules, the device attempts to locate a match
between the incoming request URI and (according to the description order):
a.
Unique contact - the Contact generated by the SBC application and sent in the
initial registration request to the serving proxy
b.
Registered AOR - the AOR of the incoming REGISTER request
c.
Registered contact - the Contact of the incoming REGISTER request
If registrations are destined to the database (using the above rules), the device does
not attempt to find a database match, however instead replies with 200 OK (used for
Survivability). Once a match is found, the request is routed either to the contact
received in the initial registration or (if the device identifies that the user agent is
behind a NAT) to the source IP address of the initial registration.
43.14.4
Registration Refreshes
Registration refreshes are incoming REGISTER requests that are associated with a
specific registered user. The association is performed by searching the internal
registration database. These refreshes are routed to the serving proxy only if the
serving proxy 'Expires time' is about to expire; otherwise, the device responds with a
200 OK without routing the REGISTER. Each refresh also refreshes the internal timer
time set on the device for this specific registration.
