Mitel OpenScape 4000 Configuration Example

This example demonstrates a basic configuration of anynode as a software SBC with OpenScape 4000 using SIP trunking. The configuration is typically carried out through the Man-Machine Language (MML) interface using Administration and Maintenance Orders (AMOs), or alternatively via the Web-Based Management (WBM) interface. A basic familiarity with both tools is assumed.

The following elements are involved in this SIP trunk setup:

  1. Board Configuration Switching Unit (BCSU): Defines the switching unit responsible for managing board-level communication. Initial board activation and logical assignment are handled here.

  2. Common Gateway Board (CGWB): Specifies the physical or virtual gateway board used for SIP trunking. IP parameters, board type, and operational mode are configured in this section.

  3. Trunk Groups (BUEND): Creates logical trunk groups that bundle voice channels. These groups serve as the basis for routing and dial plan logic.

  4. Digital Trunks (TDCSU): Assigns digital trunks to the defined trunk groups. Channel count and direction are specified here.

  5. Trunk Routing (RICHT): Configures routing paths for incoming and outgoing calls. Includes destination numbers, trunk group associations, and routing priorities.

  6. LCR Outdial Rule (LODR): Defines dialing rules for Least Cost Routing (LCR), including number manipulation and route selection logic.

  7. LCR Routes (LDAT): Maps LCR rules to specific trunk groups, determining which route is used for a given dialed number.

  8. Digit Analysis (WABE): Analyzes dialed digits to determine call type (internal, external, service) and applies appropriate routing logic.

  9. LCR Dialplan (LDPLN): Combines LCR rules and routes into a coherent dial plan structure for outbound call handling.

  10. Class of Services (COSSU): Assigns service classes to subscribers or trunks, controlling access to features like external dialing, call forwarding, and conferencing.

  11. Class of Trunks (COT): Defines trunk-specific properties such as allowed call types, cost categories, and restrictions.

  12. Class of Parameters (COP): Fine-tunes system behavior for trunks and subscribers, including signaling and feature parameters.

  13. Reference Clock Table (REFTA): Configures timing synchronization for digital interfaces, especially relevant for TDM or ISDN environments.

  14. Gateway Properties: Sets SIP gateway-specific parameters such as transport protocol (UDP/TCP/TLS), port numbers, NAT handling, and registration behavior.

  15. SIP Trunk Profiles: Defines SIP profiles including header formatting, timers, and interoperability settings tailored to the SBC or provider.

  16. SIP Parameters: Adjusts SIP signaling behavior, including keep-alive intervals, domain mapping, and contact header configuration.

  17. Codec Parameters: Specifies supported codecs (e.g., G.711, G.729), packetization settings, and transcoding options.
