CreaLog Service Delivery Platform (SDP)

Multimedia Applications for Telcos

Communication Service Providers (CSPs) are faced with tremendous changes taking place in their networks. Margins are shrinking and new threats are constantly arising from global OTTs, including alternative, free-of-cost communication and messaging applications. CreaLog has a solution to this challenge with our CreaLog Telecom Platform, which is completely “Made in Germany” and fits into any CSP network. With full support for geo-redundancy and comprehensive cluster capabilities, we can guarantee Carrier and Telco-grade availability.

And this is just the start. The CreaLog Service Delivery Platform is a comprehensive Fixed Mobile Convergence (FMC) platform for all communication, signaling, media, and messaging applications on the telecommunications market. It provides a layered architecture and is tailored to the specific needs of CSPs. Its access layer integrates seamlessly into any signaling network and is able to terminate all communication channels including voice telephony, video communication, SMS, MMS, WebRTC, and interactive Web sessions on to voice-first devices such as Amazon Alexa or Google Home. Our platform leverages applications for NGN and IMS infrastructures but also supports legacy TDM networks.

CreaLog SIP Application Server

The CreaLog SIP Application Server (SIP AS) is built on the proven CreaLog Platform 7 which has routed billions of calls since its first deployment more than 25 years ago, and perfectly fits into your IMS-System.

Unmatched Control

It gives you unmatched control over your calls using standards like RFC 4240 and RFC 5552 to intelligently screen, route, transfer, and initiate SIP calls. In addition, the SIP AS can be combined with traditional SS7 IN Servers for INAP and CAMEL.

Interworking with MRF

The SIP AS can interwork with the CreaLog SIP Media Resource Function (SIP MRF) or third-party MRFs. It is built on a proven Host-based Media Processing (HMP) engine, which supports all relevant codecs like G.711, HD Voice (G.722), AMR-WB and AMR-NB. The CreaLog SIP Media Server has played, recorded, conferenced and signaled trillions of VoIP packets and gives you complete control over those packets with its VoiceXML IVR and speech application engine.

State-of-the-art speech recognition (NLU) and text-to-speech

The SIP Media Server can be enhanced with state-of-the-art speech recognition and text-to-speech (speech synthesis) by supporting the MRCP standard. All you need to add is your own media application - or deploy pre-built or custom applications provided by CreaLog.

The CreaLog SIP Appliance delivers VoiceXML IVR, speech recognition, TTS (speech synthesis), call conferencing, call recording and an optional built-in TDM-to-SIP VoIP gateway. It integrates rapidly with both new and existing TDM, NGN, and IMS deployments.

The CreaLog SIP AS and MRF servers fully support virtualization but can as well be deployed in a rack-mount server.

Number Translation Services and Server (NTS)

Broad Choice of Routing Options

CreaLog NTS supports a comprehensive range of freephone, universal access number, and premium number services, which are typically known by their dialing prefix codes like 8XX, 08XX, 9XX and others. The solution translates these numbers into specific end points that business customers can freely configure and reconfigure according to their needs to achieve true Fixed Mobile Convergence (FMC).

CreaLog NTS offers the following full range of time, origin and service number dependent routing options for all media to achieve full Fixed Mobile Convergence for true Unified Communications and Collaboration (UCC). 

  • Time-dependent routing -> Calendars for daily, weekly, monthly, yearly or one-off times periods.
  • Origin-dependent routing -> Calling party’s number prefix, calling party category (CPC – e.g., payphone), calling identity restricted, calling identity not available, international, and operator calls.
  • Service number dependent routing -> Common routing behavior for all calls followed by differentiating according to the service number dialed.
