simple connect to conference Sample

A simple inbound application that connects an answered inbound call to a named conference.

This application uses the connect to conference action to make an outbound call to a conference named "ATestConference". It sets a number of parameters that control how the call participates in the conference and what media is played to the conference before connecting to the inbound call.

Some audio (holdmusic.wav) is played to the inbound call until the outbound call is answered. Once answered and until the conference starts it is played some different audio (whileconfstopped.wav).

This sample requires one Extra Channel. Please configure your inbound service accordingly.
It also requires the wav files holdmusic.wav and whileconfstopped.wav to be available in the cloud media store.

Uses actions: Connect To Conference, Play
