Do I keep my number?
Yes. You set up call forwarding once on your phone, landline or mobile, and your customers dial the same number as before. Call forwarding, step by step.
Does it sound like a robot?
No. A natural voice, in the tone you choose, that introduces itself right away as your AI assistant. The easiest way to judge: call her at 01 62 04 55 66 (French-speaking demo line).
Is there a commitment?
No. The subscription is monthly and you cancel from your account, with no fees and no letter to send. And for 30 days, if Sylen isn’t right for you, you get your money back.
How do I find out about a call?
By email, after every call: who called, what for, and what was done (appointment booked, message taken). There’s nothing to listen back to.
What if my customer wants to talk to me?
If it’s urgent based on the criteria you set, she puts the call through to you right away. Otherwise, you get the call summary at once and call back whenever you like.
What does she do when she doesn’t know the answer?
She doesn’t make it up. She answers with what you taught her (hours, services, rules) and, for anything else, notes the question and passes it on in the call summary so you can call back.
How does she learn my business?
She starts from your trade: the vocabulary, the common requests, what’s urgent and what can wait are already set up. Then you adjust what’s specific to you, like a transfer rule or a question never to handle over the phone.
Can she take several calls at once?
Yes. Your plan sets a number of minutes per month, not a number of simultaneous calls.
