More services, less platform complexity

CreaLog brings proven intelligent network services and modern SIP applications together on one shared Service Delivery Platform. Operators can develop existing services further, launch new offerings and integrate different applications consistently into their network and backend landscape.

Modernise

Move existing IN and VAS services to SIP and IMS step by step.

Consolidate

Bring several separate solutions together on one shared platform.

Monetise

Launch new B2B, routing, prepaid and call completion offerings faster.

Operate

Manage services, tenants, reporting and backend integration centrally.

Modernise your IN services with a clear migration path

Together, we will assess your existing service and network architecture, identify suitable initial migration steps and develop a roadmap for the transition to SIP- and IMS-based services – tailored to operations, integration and further development.

Self-service, integration and operation

  • Web-based self-service interface for destinations, service hours, announcements and overflow – role- and multi-tenant-capable

  • Number portability, ENUM and network data feed into the routing decision

  • Integration into SIP, IMS and legacy IN networks as well as OSS/BSS via APIs (automated provisioning)

  • Central monitoring, reporting and routing records for service assurance and troubleshooting

The platform behind the services

The applications are based on the CreaLog Service Delivery Platform. The SIP Application Server controls signalling, routing and service logic. The Media Resource Server adds announcements and interactive voice functions. Through the Service Creation Environment, services can be configured, extended and integrated into existing backend systems.

The integrated platform architecture is also the basis for secure, highly available and transparent network operation. TLS and SRTP protect signalling and media streams. High availability, geo-redundancy, overload protection, continuous health checks and automatic failover secure the availability of the services. Monitoring, logging, tracing, audit trails and role-based access control provide control, traceability and reliable operation.
