Hi All,

Would it be possible for ser to send a request to natted UAcs that will elicit a response from the actual phone? Something like an options query from SER to the phone?

With bi-directional udp package on regular intervals we would have a better chance of keeping NAT sessions working with a large range of NAT devices, without having to put special features (STUN, "Firewall Bullets", etc...) in every phones.

Thoughts? -Jev
