==============================================================================================================

A delegated line, or bridged call appearance (BCA), is a phone extension shared by a group of users. These users can answer and make calls on behalf of the delegated line [using the HUD feature](https://support.ringcentral.com/article-v2/Managing-your-HUD-extensions-in-the-RingCentral-app.html?brand=RingCentral&product=RingEX&language=en_US#GUID-b507eac1-f3ac-4b88-a151-fcda0590fe9b "").

Once an admin [creates delegated lines](https://support.ringcentral.com/article-v2/Configuring-delegated-lines-RingCentral-account.html?brand=RingCentral&product=RingEX&language=en_US#Configuring-delegated-lines-RingCentral-account ""), group members need to turn on their HUD and [add the extension](https://support.ringcentral.com/article-v2/Managing-your-HUD-extensions-in-the-RingCentral-app.html?brand=RingCentral&product=RingEX&language=en_US "").
