SIP Routing Proxy

Integrated Routing solution

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

General Call Flow

Routing Proxy Call Flow

Routing Proxy replies based on the Routing table the supplier Prefixes where the NGN Switch(SBC) can make the static routing decision.

Practical Example

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.

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.
