Use these features to identify an extension to which a doorphone is connected. A doorphone is
usually placed near an entrance, to screen visitors. You can connect up to two door phones to the system—use Doorphone 1 Extension (#604) to identify the extension for the first doorphone and Doorphone 2 Extension (#605) to identify the extension for the second doorphone.
- An extension cannot be used for a doorphone and a hotline at the same time. However,
hotlines and doorphones can have the same alert extensions.
- You should not assign doorphones to extension 10, 11, or to the first two extensions of any 308EC or 206 modules.
- Remove voice messaging system mailboxes from doorphone extensions.
- You cannot bridge two doorphones together.
- To prevent outside calls from being made or received on the doorphone, use Line Assignment (#301) to remove all outside lines and/or Pool Extension Assignment (#314) to remove all pools from the doorphone extension. (Automatic Line Selection for the doorphone extension will be automatically set to select intercom lines first.)
- You can use Message Light On with the doorphone (for example, the doorphone’s lightflashes as a prearranged signal to a delivery person) provided the doorphone is connected to a processor module or to a Release 3.0 or later 206 module.
