2The "Missed Call Summary Subscription" field is disabled by default. To enable this field, check the box.

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).

3The "Missed Call Summary Subscription Period" field is enabled with a default value of 86400. To disable this field, enter zero (0), or leave the field blank.
