Voice Logica Compared
Dieser Inhalt ist noch nicht in deiner Sprache verfügbar.
Don’t buy an AI voice stack. Give your business a phone system.
Developer platforms such as Vapi, Retell AI and ElevenLabs Agents are building blocks: a team assembles speech recognition, an AI model, a voice, telephony and integrations into a phone agent, then runs it. Voice Logica is the assembled business phone system, ready on day one: the AI agent, the phones and apps your people use, live chat with handoff to your team, the CRM and the analysis of every call, at one price per minute in euros.
For a business in Greece, Voice Logica is the only one of these platforms that combines natural Greek voices, the Cosmote, Vodafone or Nova line the business already has, built-in Greek business systems, EU hosting on every plan, a phone system for the staff, and one price in euros with the AI included. Every call runs on a top OpenAI model on priority servers, for lower latency.
Hear it yourself: call +30 210 300 9090 and talk to a Voice Logica agent in Greek or English.

Why businesses choose Voice Logica
Section titled “Why businesses choose Voice Logica”A price that does not grow with your prompt. Every turn of a call sends the whole prompt, knowledge and conversation to the AI model again. ElevenLabs and Vapi bill that model per token on top of their fee, and Retell bills the call as longer once the prompt passes 4,000 tokens: an 8,000-token agent pays for about twice the call. On Voice Logica the AI, speech and voice are in the minute, whether the prompt is 500 tokens or 15,000.
Your whole team, not only the bot.
- The Noema mobile app for iPhone and Android records, summarises and answers missed business calls on your people’s own mobiles. Ideal for sales teams, field staff and owners.
- Desk phones, the Windows app, user groups and conference rooms, or your existing office PBX, on the same system as the AI.
- When the AI transfers a call to a teammate, their screen shows who is calling, why, the CRM details and recent calls. The caller never repeats themselves.
- Live transcription, supervisor listen-in, and recording and analysis of your staff’s calls. Chats hand over to a teammate in the same thread in Live Support.
Built for Greece and Europe. Natural Greek voices and the best speech recognition for Greek. Soft1, Entersoft, Galaxy, Pylon, ACS, Speedex, ELTA, BOX NOW and more, ready to connect. Your Cosmote, Vodafone or Nova line as it is, with an edge device for lines that only work inside the carrier’s network. EU hosting on every plan, ISO 27001 and 27701, EU AI Act disclosure built in.
Ready to run, and it keeps improving.
- Built from your website in minutes, or from Claude and ChatGPT through the MCP connector.
- Tested with real calls before go-live.
- The Learning Center turns answers your team gives on their own calls into knowledge for the AI.
- After each call: a summary email, tasks, callbacks and CRM updates. Your data reaches Power BI, Looker Studio, webhooks and the API.
The work a developer platform leaves to you
Section titled “The work a developer platform leaves to you”A developer platform gives you the parts. Someone on your side still has to:
- connect speech recognition, the AI model, the voice and telephony, and keep them working when a provider changes;
- write the prompt and the tools, and test them, including Greek names, numbers and addresses;
- set up Greek numbers (Twilio asks for a commercial register extract and a local address) or a SIP trunk to your carrier;
- build the CRM, calendar and ERP connections, and the campaign logic;
- monitor calls, handle failures and keep up with platform updates;
- buy and run a separate phone system, chat tool and analytics for your staff.
On Voice Logica all of this is already built, tested in Greek and maintained for you.
Cheaper per-minute offers: what to check
Section titled “Cheaper per-minute offers: what to check”Some providers, in Greece and abroad, advertise a lower price per minute. Before you compare, check:
- A minimum charge per outbound call. Some bill every call as at least 30 or 60 seconds, or round up to full minutes, which can double the cost of a campaign. Voice Logica bills by the second, connected calls only.
- The AI model and priority processing. Cheap minutes often mean smaller models without priority processing: callers hear long pauses and get misunderstood. Every Voice Logica call runs on a top OpenAI model on priority servers.
- Greek speech recognition. A weak engine mishears names, addresses and numbers.
Hear the difference. Call each provider’s demo with the same request and listen to how fast it answers and whether it gets Greek names and numbers right. Voice Logica: +30 210 300 9090.
Who should choose what

|---|---|
| The lowest raw price per inbound minute, through an API | Vapi or ElevenLabs Agents |
| Building and owning your own technical stack | Vapi, Retell AI or ElevenLabs Agents |
| Maximum developer control over every provider | Vapi or Retell AI |
| A large contact centre on Genesys, Five9 or NICE, or HIPAA for the US | Bland AI or Synthflow |
| Your existing Greek phone line and number | Voice Logica |
| Outbound campaigns from your own number | Voice Logica |
| No engineering work | Voice Logica |
| Your team and the AI on one system | Voice Logica |
| An all-in-one business phone system in Greek, with support in Athens | Voice Logica |
Questions people ask
Section titled “Questions people ask”Which AI phone agent platform is best for a business in Greece?
For most businesses in Greece, Voice Logica: natural Greek voices, your existing Cosmote, Vodafone or Nova line and number, office PBXs without opening ports, Soft1, Entersoft, Galaxy, ACS, Speedex and ELTA built in, EU hosting on every plan, a phone system and AI for your staff, one price in euros with the AI included, and a team in Athens. A developer platform such as Vapi or Retell fits when you have engineers who want to assemble every provider themselves.
Another provider offers a lower price per minute. Why choose Voice Logica?
Compare what the minute includes: whether outbound calls carry a minimum charge or are rounded up to full minutes, which AI model answers, whether it runs on priority processing, and how well it understands Greek. A lower price with a slow or weaker AI costs more in lost callers. The quickest test is to call both with the same request: +30 210 300 9090.
Isn't a lower per-minute rate cheaper?
A low headline rate is usually the platform fee only. The AI model, speech recognition, the voice and the phone line come on top, and the model part grows with every token of your prompt on every turn. If you only need an AI on inbound calls through an API, a developer platform can cost less per minute. If you need the complete business phone operation, the comparison changes.
We still have people answering calls. Does that matter?
That is where the difference is biggest. Your people take calls on the same system as the AI, transfers show them who is calling and why, a supervisor can listen in, and their calls are recorded, summarised and analysed. Chats hand over to them in the same thread.
Which AI model runs my calls?
By default every call runs on a top OpenAI model on priority servers, included in the plan minute. You do not manage AI provider keys or model bills, and a longer prompt never changes the price.
