Missed Call Summary Subscription
The “Missed Call Summary Subscription” feature allows missed calls that have been redirected
by the server, to be incremented in the missed calls indicator on the phone it was initially directed
to. This feature is called the Missed Call Summary Subscription and can be set with a timer that
allows the phone to use the feature for a period of time before the timer expires. For this feature to
work, you must configure voicemail on the phone that the call was initially directed to.
For example, phones A, B, and C are connected to the server. You configure the server to direct
calls coming into phone B (which has voicemail configured) to be forwarded to phone C. When
phone A calls phone B, the server forwards the call to phone C. With this feature, phone B receives
notification from the server that the call was forwarded and the missed calls indicator is
incremented on phone B.
An Administrator can configure this feature on a global or per-line basis, using the configuration
files or the Aastra Web UI.
