Hi all,<br>
<br>
My scenario is caller->outbound proxy->proxy server->outbound proxy->callee.<br>
<br>
The outbound proxy will run topology_hiding/match_dialog() after receiving<br>
the requests<br>
returned from the proxy server.<br>
<br>
When I use some kind of Polycom video phone, PRACK requests triggered.<br>
Because<br>
1) PRACK requests are sent ahead of 200 OK of callee and<br>
2) match_dialog() works only after the outbound proxy processes the 200 OK,<br>
PRACK requests will be looped many times between the outbound proxy and the<br>
proxy server<br>
until the outbound proxy receives the 200 OK.<br>
<br>
A solution to this issue is having a flexible fix_nated_contact() to allow<br>
me to do something<br>
like ``fix_nated_contact("sip:$tU@OutboundProxyIP")''. I am wondering that<br>
it is possible for<br>
OpenSIPS to meet this requirement. Thanks.<br>
<br>
Best wishes,<br>
Chen-Che<br>
<br>
