An alternative to Retell AI for teams in Europe
Retell AI automates inbound and outbound phone calls with voice agents and serves many industries, with per-minute pricing and SIP trunking. SwissAI covers inbound calls, chat and WhatsApp with agents hosted in Switzerland. Here is how they compare.
Where the two differ
- Hosting: SwissAI runs in Switzerland by default, for every account. Retell mentions on-premises deployment for enterprise customers with data residency requirements.
- Calls: SwissAI agents answer inbound calls, on the phone, from a website button and in text. Retell also offers outbound calling.
- Telephony: on SwissAI each agent has a SIP URI, PBXs are enabled by IP address, and numbers can be registered or requested from the dashboard. Retell supports SIP trunking for existing numbers.
- Pricing: both bill per minute. SwissAI plans include minutes, with one rate covering models and telephony; Retell's rate varies with the models and add-ons chosen.
- Multi-customer: SwissAI has customers with their own agents, tools and price lists, and an API that returns each customer's calls and costs.
When SwissAI is the better fit
- Your customers or your regulator expect data to stay in Switzerland or Europe.
- You take calls, you do not make them.
- You resell voice agents to your own customers and need per-customer billing.
- You prefer configuring agents in a dashboard and exposing a few HTTP tools.
When Retell may fit better
- You need outbound campaigns.
- You want to choose specific models and add-ons per call.
