  Hi Andrei,

 The problem to me is, that almost never it returns true, since most
 clients have buildin STUN today.

 However, X-lite, Grandstream and some others I've tried all send the
 public IP address also for Symmetric NATs, hence Client<->Client will not
 work without rtpproxy. 
I thought X-Lite was one of the few which got it right.

 Any suggestions on how to solve that with nat_uac_test ? 
Try the attached patch. It adds a new nat_uac_test flag (16) that will
test for differences between the source port of the message and the port
in via.
Usage:
nat_uac_test("16")
or to include all the common tests:
nat_uac_test("19")   ( private ip in contact | src ip != ip in via | src
port != port in via)

(like all the other via tests, it makes sense only for requests)
