Creating and Managing Bridged Extensions 101If a call is made to extension 1077, it can be answered using any of thefollowing buttons:■ Extension 1077 (primary telephone) — button 4■ Extension 1088 (secondary telephone) — button 10■ Extension 1099 (secondary telephone) — button 3Secondary telephone 1099 has only two extension appearances for the1099 extension because button 3, by default an extension appearancefor the local telephone, has been used as a bridged appearance ofextension 1077.The primary telephone has buttons 1, 2, and 3 as local appearances of itsown extension (1077). If multiple calls arrive at this telephone, theyappear on buttons 4, 5, 6, 7, and 8, followed by 1, 2, 3.Buttons 1, 2, and 3 on the 1077 telephone are not defined as bridgedextension appearances. Therefore, they do not appear on either of thesecondary telephones. If the owner of the 1077 telephone makes a callusing any of these buttons, there is no indication (status light) of the callon either secondary telephone. If there are five active calls on the 1077telephone, and a sixth call is made to that extension, it rings only on the1077 telephone, on the first unused button in the 1, 2, 3 group).Defining BridgedExtensionsThe process of defining bridged extensions involves:■ Defining Bridged Extensions on a Primary Telephone■ Defining Bridged Extensions on a Secondary TelephoneDefining BridgedExtensions on aPrimary TelephoneOn a primary telephone, you can define from 1 to 11 buttons as bridgedextensions.
