Lobby Call Sample

[v-nyerkala]

Purpose

This sample demonstrates how to utilize the Call Automation SDK to implement a Lobby Call scenario. In this setup, users initially join a lobby call and remain on hold until an user in the target call confirms their participation. Once approved, the bot automatically connects the lobby users to the designated target call. The sample relies on a client application like the java script sample available in Web Client Quickstart.
