A Phantom Line is identical to a normal line in all respects, except that a Phantom Line is not assigned to any device as a primary line. This line type can appear as a private line on one keyset or as a shared secondary line on two or more keysets.
Phantom Lines are particularly useful as rollover lines. For example, sales representatives can have the administrator configure the primary line to roll over to a Phantom Line. This configuration is beneficial because when the representative speaks to the second party, there is great flexibility in holding, transferring, or redirecting the call.
In addition, Phantom Lines are also useful for query/intercom lines, which automatically set up a call between two users - for example, an executive and an assistant - when either user presses the Query (Intercom) key. This configuration is beneficial because both users' primary lines remain free while they are speaking to one another.This feature requires configuration in Lotus Sametime Unified Telephony and in the endpoint.
The function of a Phantom Line is identical to a normal line in all respects. Its DN can be called, and the line can be answered, held, used to originate calls, and in all other operations used in the same manner as other line types.
