Yes, and it should if the source ip:port is different from the contact
ip:port (client_nat_test("1")). However, the OK to the REGISTER is
generated by SER (by save()) and will not go through the onreply
route.Maybe you could create a SIP (ngrep) trace of the registration
process?<br>

style="font-size: 10pt; font-family: Arial;" lang="EN-GB">1) Is there
a way of getting the
user location info for manipulating it in ser.cfg ? Something like
lookup but
without rewriting anything. Basically what I want to do is check if the
caller
and the caller are NATed and belong to a certain same network then I
should not
use media proxy. The criterion for the same network would be that both
sides
are originating from the same public ip. Thus I would have to
retrieve the “received” field value for the calee and compare
it with the ip contained in the contact header field of the caller in
the
INVITE . Perhaps there is also another way to do this?<u1:p></u1:p></span></font><o:p></o:p></p>
<p class="MsoNormal"><font color="black" face="Times New Roman"
size="3"><span style="font-size: 12pt;">Not that I know of. However,
cvs head has a new type
of route where you can access the actual destination ip and port.<br>

<p class="MsoNormal"><font color="black" face="Arial" size="2"><span
style="font-size: 10pt; font-family: Arial;" lang="EN-GB">2) What
happens when I have multiple
phones registered under one user? How lookup(location) works when I
have more
than one ips in location table for the user? During tests I had a UA
behind NAT registering to SER with an ip assigned from the dhcp. After
a
while I had the UA assigned a different ip from the dhcp and the
Register on
SER under the same user name. The problem was that during registration
SER
would respond back to the UA for requesting authorisation credentials
but when
it was time to send the 200 OK message for registration , it would send
it only
to the previous location of the UA and not the one it sent the REGISTER
message
from with of course failure to register because UA would not get the OK
from
SER. I noticed that in Contact header of the 200 message there were
more than
one return ips (the old one and the new one), Of course as soon as the
old
location timed out the registration would go ok.<u1:p></u1:p></span></font><o:p></o:p></p>

<p class="MsoNormal"><font color="black" face="Times New Roman"
size="3"><span style="font-size: 12pt;">This has nothing to do with
how location works. A new
REGISTER should not NOT hit lookup(location), so you have an error in
your
script. You should run fix_nated_register() on the message. By default,
SER
will respond to the rcvd address and not Contact if they are different.<br>
