Frequently asked questions
Answers to the questions we are asked most often about web callback, call tracking and voice APIs.
Cannot find the answer you are looking for?
Contact usWeb callback — also called click-to-call or instant callback — is a call back button on your website. In one click, a visitor leaves their number and is called back within seconds by one of your advisers, at no cost to them.
No. VoxoLib is fully SaaS: you add a button to your website and calls arrive at your existing contact centre over the standard telephone network. Nothing is reconfigured on your side.
Web callback creates the call: it lets a visitor ask to be phoned back. Call tracking measures it: it tells you which marketing source produced each inbound call. They are complementary — one increases the number of conversations, the other tells you which investments generated them.
The callback button is added with a single script and can be running on your site in about five minutes. Configuring opening hours, branding and reporting takes a little longer, and our team sets it up with you.
Yes. You place the call, so it costs your prospect nothing — no premium-rate number and no hold time. Removing that friction is precisely what turns a hesitant visitor into a conversation.
Four criteria genuinely make a difference: the callback speed actually delivered, where the data is hosted, how well the tool integrates with your CRM, and the pricing model — subscription or pay-per-call.
