Details of the latest Siebel CRM 26.9 Release Update under the Continuous Delivery Model. This Update was GA on 24th September, 2026.
This comprehensive Update contains new features and delivers lots of bug fixes.
Siebel Updates – Resume Capability for Monthly Update Utilities
The Resume Capability feature for Siebel Updates enables PostInstallDBSetup and RepositoryUpdate processes to continue from the last successfully completed logical step following an interruption or failure, eliminating the need to restart the update from the beginning.
By resuming only the remaining update steps, this enhancement significantly reduces recovery time, shortens maintenance windows, and minimizes operational risk. It also improves the reliability of Siebel Update operations while eliminating unnecessary reprocessing, resulting in a more efficient and predictable update experience for customers.
Siebel Communications – TMF Open API Integration
Communication Service Providers (CSPs) are increasingly adopting TM Forum Open Digital Architecture (ODA) and TMF Open APIs to modernize their IT landscape and accelerate digital transformation. Siebel Communications now supports TMF Open API-based integrations for Order-to-Bill and agent-assisted billing care processes, providing a standardized, interoperable, and future-ready integration framework.
The solution introduces TMF Open API based integrations between Siebel CRM, Oracle Communications Order and Service Management (OSM), and Oracle Communications Billing and Revenue Management (BRM), replacing the existing Oracle Application Integration Architecture (AIA)-based integration framework. It leverages TMF 622 (Product Ordering Management API) for order orchestration and TMF 666 (Account Management API) for account and billing interactions while preserving existing business capabilities and supported use cases.
Key benefits:
- Aligns Siebel Communications with TM Forum Open Digital Architecture (ODA) and TMF Open API standards.
- Simplifies integration between Oracle Communications applications through standardized, industry-recognized APIs.
- Reduces implementation complexity, customization effort, and long-term maintenance costs.
- Improves interoperability with customer digital ecosystems and third-party applications.
- Replaces legacy integration mechanisms with a modern, scalable, and standards-based architecture.
- Provides a future-ready integration foundation that supports Communication Service Providers (CSPs) in their digital transformation initiatives
By adopting TMF Open APIs, organizations can accelerate integration projects, reduce implementation risk, simplify future upgrades, and align more closely with evolving industry standards while preserving existing business processes and investments.
