Enables or disables the Missed Call Summary Subscription feature.
This 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.
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
sip missed call summary subscription parameter, phone B receives
notification from the server that the call was forwarded and the missed
calls indicator is incremented on phone B.
Note: You must configure voicemail on the phone that the call was initially
directed to (phone B in the above example).
