[Serusers] Seperate SER and Oubound Proxy

[Kevin Brennan]

We would like to use STUN as preferred NAT traversal method but for 
those situations where STUN does not work we would offer an outbound 
proxy (configured in user agent). We would like to keep the NAT 
traversal proxy completely separate from SER. I wonder has anybody 
implemented this ? how ? and any other suggestions/feedback.
