Can't seem to get external notification of new message to work. When new message is dropped into box, you can see the system grab an outside line, holds it for about 5 seconds and drops it. If you try calling line during this time it is busied out. Trunks are supervised. Doesn't6 matter whether you select a single CO or pool. Will not complete outside call whether it is page or regular number. If you set it for extension notification it works fine. Hmmmm....
