[Serusers] ser: cannot call behind a Nat using rtpproxy

[Ladislav Andel]

Hi,
probably the solution might be that your user agent in public will have 
to re-register every minute or shorter time.
It is because the NAT binding between SER and the public user will be 
closed if there is no SIP traffic.
