<DIV>Yes, you can use fix_nated_contact instead. It is not entirely
RFC-compliant, but that's what you have in 0.8.14.</DIV>
<DIV>The has_totag() only tests to see if the INVITE has a To header, which
means that it is in-dialog and thus is a re-INVITE. An INVITE will
normally not have loose routing unless you have another SIP proxy forwarding an
INVITE to you (in which case you should assume that the other proxy handles NAT
and thus not trigger NAT-related code). You can safely remove the
has_totag() if you use force_rtp_proxy("l") </DIV>

<BR>> Since fix_nated_register does not exist with 0.8.14, will<BR>>

Subject: [Serusers] Contact Header and SDP not rewritten<BR>> <BR>>>
Hello,<BR>>> <BR>>> I have a problem whereby when a private client
rings a public client<BR>>> only the public user can hear voice and when
the public user rings<BR>>> the private user, no audio is transmitted.
After looking at the<BR>>> messages I have have determined that the
contact header and sdp part<BR>>> of the invite contains the private
address of the natted client. This<BR>>> would lead me to believe that the
registration process is incorrect.<BR>>> My problem is that I believe my
script should handle the registration<BR>>> process correctly and I
suspect that the following code is being<BR>>> skipped: I tried changing
it to nat_uac_test("19") and<BR>>> fix_nated_sdp("3") but that didnt
help.<BR>>>> if (nat_uac_test("3")){<BR>>> if (method
== "REGISTER" || ! search("^Record-Route:")){<BR>>>
log("Log: Someone trying to register from private<BR>>>
