THOR: The Future-Proof Communication Platform for Telcos

A large telecommunications provider is facing a challenge: Isolated solutions for voicemail, call routing and customer services that have grown over the years make administration difficult. Maintenance costs are exploding, scalability is limited, and every adjustment takes weeks of development time. The infrastructure consists partly of monolithic systems, is fragmented, inflexible and expensive. 

This is not an isolated case - many telcos still rely on legacy messaging platforms and struggle with the same problems and challenges. These range from rising operating costs (OPEX) due to inefficient infrastructure, long development cycles for new features and services, complex maintenance and inconsistent customer experiences to a lack of scalability in a rapidly changing market landscape. At the same time, the telecommunications industry is undergoing rapid change: There has long been a shift to Kubernetes-based, cloud-agnostic services that demand a flexible and scalable approach. Customers expect seamless communication across different channels and new technologies such as 5G and AI require more powerful platforms. Additionally the move towards cloud-native, API-first architectures, and AI-driven messaging is putting telcos under increasing pressure. 

“And this is exactly where the dilemma becomes apparent,” explains Michael Kours, Product Manager Voice & Messaging at Tallence AG. “How can telecom providers reduce this complexity without sacrificing flexibility or performance, how can they meet customer requirements and market pressures?”

This is where THOR 11 from Tallence AG comes in, leading telcos out of the impasse. Built on years of experience, THOR is a highly scalable, modular platform that seamlessly integrates all telecommunications services in a single, cloud-based infrastructure. No patchwork of legacy systems, no costly workarounds - instead a powerful system that grows with the requirements of the future.

THOR 11 enables telecommunications providers to manage multiple brands, network providers (NatCos) and products on a single infrastructure. Whether voicemail, security solutions or call services - each service is centrally controlled, with the flexibility to map different brand identities, languages and call flows.

„Over 50 million customers already use THOR 11, with a capacity of 10,000 parallel transactions,“ Michael notes. „Certainly a proof of the platform's scalability and efficiency. And of course, individual customization is also a key aspect. We will be talking to customers about this topic in particular at the Mobile World Congress in Barcelona this year. I cordially invite you to be part of it.“

Seamless communication across all channels, brands and products

THOR 11 enables operators to manage multiple services through a single, high-performance infrastructure:

• Voice Mail: fixed & mobile, Voice2Text, 5G-ready, native Visual Voicemail for iOS & Android
• Peering Services: SIP header verification, transcoding, abuse detection
• IN-Services: call distribution, traffic control, number manipulation
• Security Services: authentication via VoiceIdent, SMS, PAI, email, voice CAPTCHA
• Customer Services: prepaid top-ups, fee announcements, chat
• AI-Services: customer bots, intelligent call routing, predictive analytics

Ultimate voicemail solution: reliable, flexible & customizable
The core use case for THOR 11 is providing a reliable and flexible voicemail system with comprehensive features. It seamlessly adapts to different brands and languages using customizable templates. Additionally, communication channels such as SMS, callback, and MMS can be tailored based on brand-specific settings or user preferences, ensuring a personalized and efficient user experience.

Optimizing Efficiency, Customer Experience, and Cost Reduction
THOR 11 revolutionizes communication infrastructure by unifying multiple services into a single, scalable platform. Fragmented solutions are replaced with seamless integration across multiple NatCos, brands, and languages, ensuring greater operational efficiency and streamlined service delivery.

Streamlined missed call alerts (MCA)
THOR enables you to manage missed call alerts effortlessly, customizing message templates for different brands and languages while delivering notifications via SMS, MMS, or email – all within a unified system.

AI-Powered fault reporting system
You boost customer satisfaction with an advanced fault reporting system accessible via email, SMS, web, voice (ASR), or app. This system automatically verifies user identity through SMS, callback, or credentials, conducts an initial fault analysis, and keeps users informed through their preferred communication channel (SMS, email, or call). Incidents are seamlessly integrated into your ticketing system, ensuring efficient resolution without additional manual effort.

Smart AI-Driven Customer Engagement
By leveraging AI personalized service recommendations can be delivered, such as intelligent tariff updates based on customer communication preferences via eMail, SMS or call. This provides proactive support and improves the user experience with targeted, automated suggestions.

Seamless Expansion & Resilience
Designed for unmatched reliability in telecom networks, THOR 11 leverages distributed deployment across multiple Kubernetes clusters. This ensures optimal scalability and load balancing, enabling effortless network expansion while maintaining peak performance.

Unbreakable Uptime & Failover Protection
Engineered for maximum availability, THOR 11 features automated failover mechanisms, instantly redirecting calls to another node in case of failure – ensuring uninterrupted service for customers.
