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).
