ProSBC TechTraining - 205 - Call Routing

This ProSBC training video dives deep into the mechanics of call routing within the ProSBC system. It starts with a broad overview and progressively unpacks the multiple routing techniques supported—such as internal routing tables, customizable routing scripts, and external server integrations like Radius and SIP Redirect. In this session we explore its flexibility, offering detailed guidance on load balancing, retry logic, error handling, and regular expression-based routing decisions. You will learn how the system matches incoming calls using attributes like calling number and NAPs (Network Access Points) and how these can be remapped or modified on their way to the destination. Practical examples are provided for designing effective routing tables and scripts. There's also an extensive section on debugging tools, regex logic, test simulations, and CDR (Call Detail Record) customization for billing and diagnostics. Throughout, the focus remains on empowering users to optimize call flows according to their specific network and business logic requirements. 00:34 - Introduction to call routing concepts 01:31 - Call enters system and goes through routing scripts 03:18 - How internal routing table works 04:48 - Custom routing scripts and use cases 05:50 - Integration with Radius servers 07:54 - SIP redirect server operation 10:40 - System latency for routing 14:24 - Configuring incoming/outgoing call attributes 17:20 - Using regular expressions for call matching 19:53 - Call retry logic and priority/weight balancing 26:00 - Custom error-based retry rules 30:05 - Regex patterns explained for digits 38:00 - Match groups and dynamic prefix replacement 42:01 - Testing routing logic in the system 46:00 - Debugging with call trace and NAP status 51:20 - SIP routing call flow inside applications 57:39 - Explanation of routing stages (before/after filters) 1:03:56 - Max call duration and custom call parameters 1:06:06 - Sample routing scripts for customer needs Slides can be downloaded from: https://www2.telcobridges.com/l/45842/2020-03-16/8cszst More on ProSBC at: www.prosbc.com About TelcoBridges: TelcoBridges is a leading provider of carrier-grade telecom software and hardware, dedicated to supporting telecom operators and enterprises worldwide.
