summary subscription		aastra.cfg, <mac>.cfg
Missed Call Summary
Subscription
(in Web UI)
Description	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
	phone B, the server forwards the call to phone C. If you enable the 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).
Format	Boolean
Default Value	0 (disabled)
Range	0 (disabled)
	1 (enabled)
Example	sip line1 missed call summary subscription: 1
