Hello,<br>is there an easy way to check if my opensips instance is the last proxy before the UAS?<br>I need this to avoid calling nat_uac_test/fix_nated_contact in my onreply_route in case I'm receiving a response relayed by another proxy.<br>
I was thinking I could test if i'm in the top-most Record-Route in the reply, but I was unable to figure out how to do it.<br></blockquote><div><br>Reading the page about transformations, I think something like this would work:<br>
<br>if ( $(hdr(Record-Route)[0]{uri.host}) == myself ) {<br> ....<br>}<br> </div>However, I think to implement a generic way to handle this would become very convoluted: I was thinking that I should do this considering the possibility of dealing with redirection and downstream proxies that would do not record_route or would do it conditionally. So I would have to check this, set some parameter in Record-Route, take care in case of branching and checking the Route header etc, etc.<br>
But I think this is a lot of trouble and will not actually happen in our network.<br>So I will write my cfg just testing:<br><br>if ( !from_gw() ) {<br> fix_nated_contact();<br>}<br></div><br>because I just need to fix the contact of the registered users.<br>
