After browsing you can select from menu something like 'Quit browsing' and
user agent correctly sends disconnect event. But I suspect if you simply
press HangUp button, UserAgent simply go out without disconnect event.
(I checked it at least with some phones).
And users mostly end its sessions by this way.
So if you have heavy load it becomes the problem.

For example our WAP gateway grows approximatly at 100MB every day.

So I agree that this is phone problem, but I think kannel must
handle it someway.
