Studio integraon with outside sources like telephones, codecs and Opal is a two-way process. The guest must send his audio to the

studio, but also receive a return feed that allows him to interact with other sources, like a host. An important element of remote studio

voice integraon involves allowing a speaking party to hear his own voice in his own earpiece. This sidetone provides a speaker the

comfort of knowing his voice is geng through, and makes two-way communicaon ow more easily.
