Configuring Advanced Operational Features

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
