<font face="monospace">Hi Li,<br>
<br>
Somehow we are going in circles here :). So, could you post a pcap
for call going via your B2B (showing all in and out SIP messages)
and mention which frame is the outgoing request you cannot modify
?<br>
<br>
Regards,<br>

<p class="MsoNormal">Thanks for the explanation. I mean that the
local_route can take effect for the forwarded INVITE(from
incoming ones) in our proxy, but not after b2b_bridge. I’ll do
more debugging on it since the messages should be visible.
Thank you very much.<o:p></o:p></p>
