Dear,
some sip-phones behind the symmetric nat, can not be
registered, if the ip of stun server was filled ,in
the setting of sip-phone.
1. why not?
2. This is probably a bug in the SIP phone. the SIP phone should detect
(by means of STUN) that it is behind sym. NAT and should not try to do
NAT traversal by itself.
3. Nevertheless, if the SIP client sends REGISTER requests (even with
wrongly assumed public IP addresses:port) you can fix this by applying
NAT traversal in the proxy.

I am looking for a way,that all of sip-phones, with
the same setting , work properly.
may be a solution, the stun server doesn't reply to
the request behind the symmetric request,
what is your idea?
best
Mani
