Language detection by phone prefix: greet every caller in their language
The first sentence of a call sets the tone for the whole conversation. With language detection by phone prefix, your agent greets callers in the right language from "hello", with no "press 1 for English" in the way.
How it works
When a call comes in, the agent reads the international prefix of the number (+34, +49, +33...) and switches to the language you mapped to that country. A call from Germany is handled in German; one from France, in French. All automatic, with nothing for the caller to choose.
How to set it up
- Choose the prefix language mode on the agent.
- Map each prefix to its language (+49 → German, +33 → French...).
- Set a default language for prefixes that aren't mapped or can't be read.
That covers the expected cases and, whatever happens, the call is always answered.
Who it helps
- Companies with a single number taking calls from several countries.
- Teams that want to drop language-selection menus and feel closer to customers.
- International businesses after professional service without a complex setup.
Paired with the new languages and multilingual agents, this mode turns your number into a switchboard that speaks each customer's language.
Frequently asked questions
- How does the agent decide which language to speak?
- With prefix detection, the agent reads the country code of the incoming number (for example +49 or +33) and automatically picks the language you mapped to it.
- What happens if the prefix isn't mapped?
- The agent falls back to the default language you set, so no call ever goes unanswered.
- Can I combine it with multilingual agents?
- Yes. The prefix sets the greeting language, and from there a multilingual agent keeps adapting to whatever the caller speaks.
