This article discusses extending the functionality of click-to-call, a popular feature that allows website visitors to call businesses directly with a few clicks, to simultaneously dial multiple numbers and connect the first person who answers to an agent. The updated implementation uses Twilio's simultaneous dial technique to connect the visitor to an agent, while also prompting the caller to record a message if no agents respond within 30 seconds. The code example provided demonstrates how to implement this feature using PHP and the Twilio PHP Helper library, including handling the call once connected and implementing simultaneous dial. However, it is noted that simultaneous dial may not be suitable for all situations, as it can cancel connections from other phones that pick up before a human answers.
