4. SIP Trunk Design Patterns

Presented by Robert Kinder, Cox Communications.

SIP Trunking Design Patterns are reusable solutions for frequently occurring customer implementations. The concept is very similar to software engineering design patterns to solve common programming problems. SIP Trunking Design Patterns are used by Sales Engineers to propose the best solution to meet the customer’s requirements and by order entry and auto-provisioning BSS/OSS applications to configure the network.

The SIP Trunking Design Pattern session will include diagrams and applications for the following:

  • Single Site: Small Medium Business (SMB)
  • Multi-Site Shared Capacity: SMB cost economy
  • Trunk Group Redundancy
  • Geo-Redundancy: Load Balancing, Route Prioritization, Multi-Site Sequential Route Advance/Overflow, Primary/Secondary Data Centers, Symmetrical Failover with DID-based Routing Optimization
  • SIP Trunk to ISDN PRI Failover: Alternate platform and network survivability for data centers and remote survivable gateways.
  • Business Continuity Behaviors (BC) and Options
  • User configured Business Continuity features (Call Forward Not Reachable, Call Forward Always, Personal Mobility, etc.)
  • Automatic Business Continuity features (trunk group reroute, route exhaustion)
