<DIV><FONT face="Times New Roman"><EM>I also saw your question on RFC compliance
and the Sonus equipment: In order to make Grandstream phones register properly
when using STUN behindsymmetric NAT, I had to patch nathelper with the rport !=
port of receivedaddress check. (I use 0.8.14 and I guess you already have the
patch with the development version). The reason is that Grandstream attempts to
rewrite the address using STUN even though it correctly detects a symmetric NAT.
I have seen that this was introduced in a new firmware not long ago (release
notes). This pussles me as sources I have seen claims this to beinvalid
behavior (which seems correct to me).</EM></FONT></DIV>

am facing the same problem now. Is there any solution to us? Where could I
download the nathelper patch as described above?</FONT></FONT></DIV>
