Maybe I need to explain a bit further : the call is send to the IP-phone 
and answered. The call lasts for about 1 à 2 minutes and is then 

Sometimes this happens after about 1 minute, sometimes after about 2 
minutes, sometimes it does not happen at all for a whole day or week !

If I say random, I really mean random.
I'd love to believe that there is some kind of bottleneck or level that 
is reached when this happens, but nothing points to that direction.

Kind regards,
