Solution
The SIP-AS enables telcos to provide voice, routing, IVR, AI agent and value-added services efficiently, modernise existing network services and bring new services to market quickly.
Tasks
The SIP-AS analyses incoming calls, controls SIP signalling and flexibly executes the appropriate routing, service or protection process.
Integration
Via SIP, alarming and monitoring, backend interfaces, REST APIs and connections to OSS/BSS and IMS networks.
Benefits
Launch new network services faster, consolidate existing platforms and migrate step by step from legacy IN to SIP and IMS – with little development and operational effort.
SIP AS in operation
SIP service control for modern IMS networks
The server processes SIP INVITE messages based on request URI, destination number, route header, service tags or subscriber profiles. As a terminating SIP application in B2BUA mode, it controls SIP signalling, call states, response codes and relevant headers.
Service development, media functions and routing
The CDG Service Creation Environment is used to model, test, version and extend services as modular service flows. For announcements, AI agent and fraud services, early media and DTMF, the server works together with a Media Resource Function. A key strength is the combination of full SIP control and graphical service creation.
Differentiated routing and fallback logic
Ready-made routing blocks by time of day, weekday, public holiday, origin, destination number, subscriber group, load, location or quota allow services to be realised quickly. If destinations are busy, unreachable or overloaded, the platform activates alternative destinations, announcements or defined SIP responses.
Operation, integration and multi-tenancy
O&M functions for monitoring, alerting, performance management, logging, tracing and reporting, integrable via SNMP, REST APIs and northbound interfaces. Role-based access and multi-tenancy allow self-service portals and wholesale models.
Concrete use cases for new services and revenue models
IN & SIP Services
Our IN and SIP services enable telcos to provide a wide range of value-added services – from number translation, VPN and call completion to routing, fraud prevention, prepaid and intelligent announcements – flexibly and future-proof.
B2B / Value Added Services
Our B2B VAS and AI services help telcos offer intelligent customer services, contact centre solutions, virtual PBX and proven value-added services flexibly, scalably and under their own brand.
SME AI Agent Services
The AI Agent Marketplace enables telecommunications providers to offer easily bookable, industry-specific voice and omnichannel agents with which small and medium-sized businesses can automate their customer communication, service processes and recurring tasks.
Emergency Communications
Our emergency call solutions combine central location logic, alternative routing, RTT and multimodal emergency communication into a telco-grade emergency service architecture – designed for high availability and the gradual transition to IP-based emergency services.
Recording Solutions
Our recording solutions bring compliance, enterprise and Microsoft Teams recording together on one shared, network-based and device-independent platform – multi-tenant, cloud or on-premises capable and analytics-ready, without additional data silos.
The CreaLog SIP Application Server combines carrier-grade stability with flexible service creation and full SIP control – so telcos can consolidate existing IMS services and launch new value-added services faster and at scale.
