Advanced Operational Features 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 the new feature in 2.1, 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
