How it works
A click-to-call widget starts a phone or web call depending on browser capabilities and permissions. Web chat and related widgets shorten the path from a question to support or a callback. Service quality depends on agent availability and preserved conversation context.
Business example
On a mobile page, tapping Call opens the phone dialler with the business number.
What to consider
Test mobile usability, response times, conversation privacy and escalation to a human when an automated workflow cannot help.
