1. SIP Routing Proxy Integrated Routing solution

2. General functionality  The Routing Proxy is based on Session Initial Protocol(SIP) and is acting as a SIP redirect server.  A redirect server is a user agent server that generates 3xx responses to requests it receives, directing the client to contact an alternate set of URIs.  Routing Proxy is generating SIP 302 responses, with multiple URI’s as routing choices.  Routing Proxy works together with all NGN switches supporting SIP 302 messages.  Based on customer requests Routing Proxy is able to send all SIP 3xx messages.  Prefix based Routing

3. General Call Flow

4. Routing Proxy Call Flow  Customers are identified on the Routing Proxy by an internal Customer Prefix which is send from the NGN Swich(SBC) to the Routing Proxy.  Routing Proxy replies based on the Routing table the supplier Prefixes where the NGN Switch(SBC) can make the static routing decision.

5. Practical Example

6. Operation and Maintenance  Fully maintainable through Captura Switch Export.  Backdoor maintainance through Web Gui.  Routing simulation over Web Gui.  Automatic Routing updates controlled by cronjobs.  Capable to handle all Captura Routing structures, like Special Routings, Wholesale, Premium etc.  Ability to control Peak / Offpeak / Weekend Routing.  Redundant Server architecture to provide the highest operational availability.  Database replication to redundant Routing Proxy.

7. Hardware / Operating System  Standard Intel based Servers, Quad core processors.  Working on each Server which complies with the necessary Hardware requirements.  Linux Operating System / Redhat  MySql databases, Apache and PHP for Web Gui applications.
