<br><font size=2 face="sans-serif">Hi Ruud, Hi Adrian,</font>
<br>
<br><font size=2 face="sans-serif">Thanks a lot for the quick feedback
;-).</font>
<br>
<br><font size=2 face="sans-serif">About using private IP addresses: i
did not know there might be some limitations here, but i do not see why
it should be an issue unless some specific code prevents from using such
addresses. Of course, i'm aware that usually (but not only) media proxy
is used along with NAT / NAT traversal, which always implies hiding private
addresses. </font>
<br>
<br><font size=2 face="sans-serif">From Adrian's email i understand that
media proxy is only dedicated to NAT traversal and cannot be used as a
"pure" media proxy (one might want to force RTP proxy on one
box without NAT and with private IP addresses). According to me, NAT detection
was performed by opensips only (nat traversal and nathelper modules) but
if you tell me that media proxy also holds internal mechanisms for NAT
detection, that's ok.</font>
<br>
<br><font size=2 face="sans-serif">Just for information, so far, all previous
tests with forced media proxy, without NAT and using private IPs, are all
OK, even with parallel call forking from TDM to SIP.</font>
<br>
<br><font size=2 face="sans-serif">=> can you confirm that media proxy
can not be used as a 'forced" media proxy, without NAT ?</font>
<br><font size=2 face="sans-serif">=> If no, will it work if i use only
public addresses with media proxy, avoiding its NAT detection mechanism
?</font>
<br>
<br><font size=2 face="sans-serif">According to the answer given to the
above 2 questions, I will try to upgrade my platform accordingly and will
come back to you with the results. Meanwhile, please find hereafter some
answers for Ruud's email...</font>
<br>
<br><font size=2 face="sans-serif">The objectives on my side are to place
a call from a sip user to 2 TDM users by parallel-forking this call to
2 different media gateways (please check the context details i put in the
first email).</font>
<br>
<br><font size=2 face="sans-serif">So, sip user is calling </font><font size=2><tt>8003@192.168.2.233
</tt></font><font size=2 face="sans-serif">which is registered in 2 locations
in opensips. Opensips forks the call to both gateways and it rings on both
TDM phones.</font>
<br>
<br><font size=2 face="sans-serif">When i pick up with one gateway (the
working one), it always works: i mean opensips receives a 200OK/SDP from
the gateway and sends a CANCEL to the other one, and then media is established.</font>
<br><font size=2 face="sans-serif">When i pick up with the other gateway,
it nevers work: i mean opensips receives a 200OK/SDP from the gateway and
sends a CANCEL to the other one, and then media is NOT established because
IP addresses used by media proxy are wrong (check my previous email or
provided mediaproxy logs).</font>
<br>
<br><font size=2 face="sans-serif">I think there is some wrong information
update between opensips and media proxy at some point, either with the
183/SDP messages or 200OK, because the IP @ of one gateway is taken as
RTP IP to reach the other gateway.</font>
<br>
<br><font size=2 face="sans-serif">Please find the media proxy logs below
and let me know if you need anything else.</font>
<br>
<br><font size=2 face="sans-serif">Thanks a lot again,</font>
<br>
<br><font size=2 face="sans-serif">Regards,</font>
<br>

required.</font>
