What is the IONOS AI phone assistant?
IONOS, known to many as a hosting and domain provider, has for some time also sold an AI phone assistant for businesses. The promise per the product page: the AI answers calls around the clock, answers questions, forwards calls, and, depending on the plan, books appointments. Your existing phone number stays, the assistant is placed in front via call forwarding. It draws its knowledge automatically from your website: add the URL, the AI reads out services and hours, and you add your own entries in the dashboard. Per its own statements, the system is GDPR-compliant, hosting happens in Europe, and every call lands in your overview with an email summary.
What does the IONOS AI phone assistant cost?
IONOS tiers into three plans between €39 and €99 a month, all cancellable monthly and with a free trial month. Notably: billing is per call, not per conversation minute, as most German providers do. A long call doesn't cost more than a short one.
| Plan | Price per month | Included |
|---|---|---|
| Flex | €39 | 30 calls included, then €0.49 per call; 1 call forward |
| Flex Pro | €69 | 100 calls included, then €0.39 per call; 5 call forwards; appointment booking |
| All-Flat Advanced | €99 | All calls included; unlimited forwards; appointment booking; advanced API integration; website widget |
Where the self-service approach hits its limits
The IONOS approach is deliberately lean: you set everything up yourself in the dashboard, and that's both its strength and its limit. Three points worth checking honestly before you sign up:
- Maintenance is on you. The AI learns from your website and your manual entries. If services, prices, or workflows change, you have to keep the knowledge base current yourself and adjust the call rules in the request manager.
- Feature scope depends on the plan. Appointment booking only comes with Flex Pro (€69), API integration with existing systems and the website widget only with the All-Flat-Advanced plan (€99). On the entry plan, the assistant answers and forwards to exactly one destination.
- Support is enterprise support. IONOS offers help-center guides and general support by phone or chat. A dedicated point of contact who knows your conversation flow and actively thinks along isn't part of the model: the assistant is one product among many in the IONOS portfolio.
For freelancers with modest call volume and standard requests, that's often entirely sufficient. It gets tricky when decisions have to be made on the phone: a plumbing/HVAC business has to distinguish between a burst pipe and routine maintenance, a law firm needs confidential first contact with clean data capture. Mapping such workflows in a self-service dashboard costs time and experience many businesses don't have.
What experiences exist with the IONOS AI phone assistant?
Publicly readable experiences with the IONOS AI phone assistant are mixed: on the review platform OMR Reviews it sits at 3.5 out of 5 stars from 7 user reviews (as of: August 2026). That's a thin data set — the product is young, and per the platform, some reviews came in on invitation from OMR or the provider. As a direction it still holds up:
- Praised is the easy entry into the user interface, the friendly and polite conversation flow, and that changes to the settings take effect immediately. Several reviewers from hospitality and hotels use the assistant to stay reachable outside staffed hours.
- Criticized are missing individual settings, a noticeable pause after the greeting (one review mentions almost 10 seconds), pronunciation issues with amounts, and limits of the knowledge base: the website crawler doesn't read every page cleanly, and custom content has to be maintained manually.
Both sides fit the self-service model from the section before: anyone who invests time in maintenance and fine-tuning gets a usable standard assistant; anyone who expects someone to handle edge cases hits a wall. The most honest data point remains your own: IONOS throws in the first month as a free trial — call your own assistant several times, with a standard question, an edge case, and a pricing question, before you activate call forwarding permanently.
And Telekom?
Anyone searching for an AI phone product from Telekom finds no comparable, directly bookable product: Telekom offers business customers the Conversational AI Suite, a voice AI solution for customer service, but as a managed service with individual consulting, references from enterprise and government projects, and no public price list (as of: July 2026, geschaeftskunden.telekom.de). That targets companies with contact-center needs, not the business that wants to be reachable next week. Don't confuse it with the Telekom AI Phone: that's a smartphone with a Perplexity assistant for consumers, not a phone assistant for businesses. The explainer is in the article Telekom AI Phone: what it can do, what it can't.
The managed alternative: titanspear.ai
titanspear.ai starts at the other end: instead of a self-service dashboard, the agency handles setup. We configure the voice, greeting, and conversation flow for your business, you listen in beforehand and sign off. The assistant answers calls around the clock, captures every request in a structured way, connects to your existing calendar and CRM systems, and, on request, calls back new inquiries immediately (speed-to-lead). Billing is a fixed monthly price based on call volume, not per call or minute. What the assistant can do in detail is on the page about the AI phone assistant.
| Feature | IONOS | titanspear.ai |
|---|---|---|
| Target audience | Freelancers, small teams, and growing businesses who configure their assistant themselves in the dashboard | Trades businesses, law firms, property managers, realtors, and SMEs in the DACH region |
| Setup | Self-service: add your website URL, set voice and scenarios in the dashboard, activate call forwarding — per IONOS, about 5 minutes | Agency-managed (done-for-you): setup, sign-off beforehand, dedicated point of contact |
| Depth of customization | Request manager with call rules and forwards; scope depends on plan (appointment booking from Flex Pro, API from All-Flat Advanced) | Conversation flow tailored to the business, including integration with existing calendar and CRM systems and instant callback of new inquiries (speed-to-lead) |
| Pricing model | Per-call billing: €39–€99 per month incl. VAT, cancellable monthly, 1 month free trial (as of: July 2026) | Fixed monthly price based on call volume instead of per-item billing — specifics in the free intro call |
| Support | General IONOS support by phone or chat plus help-center guides; maintenance and fine-tuning are on you | Ongoing agency support: we handle adjustments, fine-tuning, and monitoring |
Other providers at a glance
IONOS and titanspear.ai are two of several options in the German-speaking market. Providers differ mainly in target audience, type of setup (self-serve or managed), and billing model. What matters less is the brand name than the question: do you want to set it up and maintain it yourself, or should someone take care of it? The right price range for your business is clarified fastest in the free intro call.
