Lobby Call Sample

[v-nyerkala]

Purpose

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