Summary:                    [patch] Missed Calls is cleared from phone status
line
Description: 
chan_skinny is doing excessive clearing of phone status display, this
causes, that missed call info is cleared from display and can be accessed
only by entering phone missed call history, that is anoying for users.
I did packet dump of communication between skinny phone (cisco 7920) and
callmanager (4.1) and compared with packet dump between chan_skinny and
same phone (7920).
This issue is probably caused by chan_skinny, because asterisk replies to
phone's KeepAliveMessage, not only with KeepAliveAckMessage (as callmanager
only doing), but chan_skinny after AckMsg immediatelly sends also
DefineTimeDate and (2x) SetLampMessage!

Missed call issue was also discused in
http://bugs.digium.com/view.php?id=9152#64390
DEA said here, that callmanager also clears missed calls from phone
prompt, but is't not true.
