CavCom‘s TeamTalk™ hands-free line of products operate as "full-duplex" systems, meaning our units are able to transmit communications in both directions simultaneously. This means that users can speak and hear others at the same time without delay because there are two communication paths between them. Everyday examples are a cell phone conversation or a conference phone call with multiple people talking and listening at once. To eliminate confusion from too many people speaking at the same time, TeamTalk™ offers a push-to-talk mode where certain users must engage a PTT button to speak to others in the group.
