This feature is called the Missed Call Summary Subscription andcan be configured by your System Administrator. For this feature to work, you must configure voicemail on the phonethat the call was initially directed to.For example, phones A, B, and C are connected to the server. Your Administrator configures the server to direct callscoming into phone B (which has voicemail configured) to be forwarded to phone C. When phone A calls phone B, theserver forwards the call to phone C. With the Missed Call Summary Subscription enabled, phone B receives notifica-tion from the server that the call was forwarded and the missed calls indicator is incremented on phone B. See the illus-tration below.Customizable Callers List KeyYour System Administrator can specify an XML URI that creates a custom Callers List application for your phone.
