Introducing EU hosting: High-quality, GDPR-compliant conversations

For European companies, deploying AI voice agents has meant making a tough choice: prioritize performance and low latency with U.S.-hosted solutions, but risk non-compliance, or choose a fully EU-compliant option at the expense of speed and conversation quality.

This isn’t a small sacrifice. In customer conversations, even slight delays can break the flow, leading to frustration for users and missed business opportunities. AI voice agents have the potential to transform customer engagement, but only if they feel instant and seamless.

At telli, we’re committed to eliminating this trade-off. Our mission is to make every AI conversation smooth, personal, and compliant, no matter where customers are. That commitment is especially important in Europe, where data privacy standards are among the strictest in the world.

That’s why we’re excited to introduce our latest product update: EU hosting. With this new feature, our European customers no longer need to choose between regulatory peace of mind and great conversational experiences. Now, they can have both — fast, natural conversations with full data compliance.

Why EU hosting matters

With AI agents, the difference between a conversation that flows and one that falls flat is milliseconds. Previously, European customers experienced up to 300–400 ms of added latency because voice data had to travel to U.S.-hosted models and back. In live conversations, people expect instant replies, so even a slight delay can make the interaction feel off or robotic. This can cause users to hesitate, talk over the agent, or abandon the conversation altogether.

That’s why low latency isn’t just about tech, it’s what helps automated support feel truly seamless and human, keeping customers happy and engaged.

With EU hosting, telli’s AI voice agents interact with your customers from servers based in Europe, so conversations are fast and natural, and your data is always in line with the EU’s strong privacy standards.

How it works

Every call follows this same secure, in‑region path:

Calls come in over EU-based telephony.
Our EU-hosted speech-to-text system streams audio transcriptions in real-time.
With that transcript, LLMs running on Microsoft Azure’s EU servers craft a response.
Our EU-hosted text-to-speech service turns that response back into a natural voice, ready to be played to the caller.

From the first ring to the final reply, all raw audio, transcripts, prompts, responses, and metadata stay safely within EU borders — ensuring both fast interactions and full GDPR compliance without compromise.

‍What EU partners can expect

EU hosting is a complete infrastructure shift designed to meet the needs of modern European businesses. We’ve rebuilt how voice data is processed, stored, and served to ensure that telli’s AI voice agents perform at their best without regulatory trade-offs or technical compromises.

The result? Customers enjoy fast, natural conversations, and businesses stay fully protected — no transatlantic detours or compliance worries.

Here are three key benefits our partners experience:

Reduced latency

Instead of routing data across the Atlantic, conversations are now processed on servers located in Europe. This change unlocks consistently reduced response times, especially for live interactions where milliseconds shape the user experience. Customers can expect smoother, more human-feeling conversations, even in complex, high-traffic call environments.

Full GDPR compliance

We’ve localized every part of the system, including model inference, voice data processing, real-time transcription, and storage, so all data stays within the EU. This ensures full alignment with GDPR requirements such as data minimization, transparency, user consent, and data residency. European companies can now clearly demonstrate their commitment to privacy for both customers and regulators.

Flexible deployment on agent level

Not every team has the same setup, which is why we designed EU hosting to be configurable at the agent level. Whether a company operates across multiple regions or focuses on a single local market, customers can assign hosting according to their specific compliance needs without sacrificing user experience or operational flexibility. This approach enables global brands to optimize performance and privacy without splitting their workflows or sacrificing control.
