As answered by people managing LayerStack Arm-based Cloud Server and NordTell.
NordTell's answer:
Three things you rarely get together: It is honest on the phone. The agent always says it is an AI, and it never tells a caller "you're booked" before the calendar has confirmed it. It is properly multilingual. One agent can speak several languages in the same call, each with its own native voice. About 40 languages, including Danish, Swedish and Norwegian and with different voices/voice models (no other platform has this feature - hence why we have created it) It is European. Built in Copenhagen, hosted in the EU, and every AI model is named with its provider, so you know where your calls go.
NordTell's answer:
Because the price list is the whole story. You pay per minute of conversation, from EUR 29 a month. Every plan has every feature, with no per-seat fees, no per-agent fees and no setup fee.
You can also build and test an agent for free in your browser, using your microphone, before you connect a phone number. And when a caller needs a person, the agent briefs your colleague first and then puts the call through, so nobody has to repeat themselves.
NordTell's answer:
Small and mid-sized businesses whose phone rings while their hands are full: clinics, trades, salons, property managers and service companies, mostly in the Nordics and Germany.
The second group is agencies. They build phone agents for their own clients and resell NordTell under their own brand and domain.
NordTell's answer:
NordTell is built in Copenhagen by Interactive Made ApS.
We created Nortel because we were basically tired of the lack of flexibility, features, and speed that are offered by our competitors. Sometimes you can get the flexibility, but you have to pay a ton of money for it. Sometimes you get the speed, but you lack a lot of features, and this frustrated us so much that we chose to embark on the journey to create the first Nordic platform that has all the flexibility that Retail AI has, all the features that Famulor has, and the speed that nobody has - at best possible price.
So we built the phone agent we wanted ourselves: one that speaks Nordic languages well, keeps its data in the EU, shows its prices openly and never pretends to be human.
