I know of this option - it doesn't help, because the provider ignores it 
(on some calls) and the call is dropped anyway.

Normally, there is no problem with the timers. And the problem which 
occurred here is not just the timer, but the session which seams to be 
lost on both sides. But why?


Thanks,
