Hi brian, I think I agree, we found this post (<a href="http://www.mail-archive.com/users@lists.opensips.org/msg03093.html">http://www.mail-archive.com/users@lists.opensips.org/msg03093.html</a>) which mentions that failure route and branch route will be called on a failure. I suspect that mech underneath engage_media_proxy is modifying SDP c= in failure and branch. <br>
I may switch to using use/end mediaproxy, but if that is the case, I figure it may be easy enough to fix in the module itself. So I will look there first and see if I can't make up a patch. <br><br>Charles<br><br><div class="gmail_quote">

Definitely not - I know there was a lengthy discussion about calling use_media_proxy twice and that function a while ago. The only thing I do with a natted invite is this:<br><br># NAT test<br> if( is_method("INVITE") && !has_totag() )<br>
{<br> $avp(can_uri) = $ru;<br><br> setflag(3); # flag for NAT<br> force_rport();<br> fix_contact();<br> append_hf("P-hint: NAT\r\n");<br>
xlog( "L_INFO", "Engaging media proxy" );<br> engage_media_proxy();<br> }<span><font color="#888888"><br><br>Charles</font></span><div>

I have been using engage_media_proxy in my script, but it seems to cause problems when I failover in the dynamic routing module. <br>This is the scenario:<br><br>1. Incoming call<br>2. Engage media proxy<br>3. Try first GW (which is down)<br>
4. Failure route<br>5. Try next GW<br>6. Next GW sends Session progress & invite<br>7. Media proxy module 'fixes' my SDP contact twice<br><br>My SIP message end up with duplicated SDP contact info. For example:<a name="1356966f3e28ff31_135696058411793a_135694a262214eb1_13569431a4825d64_13569252baca8add_#top"><font color="#cc6600"> c=IN IP4 33.66.22.1133.66.22.11<br>
<br></font>If the first gateway works, this does not happen. In fact it works perfectly. But I guess engage_media_proxy or the dialog module is having an issue with a failure scenario?<br><br>My failure route is pretty simple:<br>
<br>failure_route[4] {<br> xlog("L_INFO", "Failure Route: $rm, $fu, $ru\n");<br><br> if (use_next_gw()) {<br> xlog("L_INFO", "Trying next gateway" );<br>
t_relay();<br> exit;<br> } else {<br> xlog( "L_INFO", "Exhausted gateway list" );<br> t_reply ("503", "Service not available");<br>
exit;<br> }<br>}<br><br>Should I switch to use_media_proxy/end_media_session if I want to expect failovers? Or could I be doing something wrong?<br><br>Thanks guys<span><font color="#888888"><br>
