Are you saying that you have to NATed clients that can communicate?
If so, the reason is that they are being the same firewall and thus can directly reach each other.

Dear Paul:
I guess that you are right. But I can not understand why I can make a call from two different NATs? Don't they communicate via my ser? Or just signal channel via ser?
Thank you for your explain.

MediaProxy is a two-part project. SER only includes the interface to the actual mediaproxy. You must install the actual mediaproxy server, which is written in Python.

Dear Paul:
So surprised it is. I never see any executable file or script named "mediaproxy.py" in my source files. I guess that the mediaproxy is only a module including in "sip_router/modules/mediaproxy/mediaproxy.so". When I can get a executable version of mediaproxy or where the mediaproxy.py is?
And also I miss the "proxydispatcher". I can find a directory named "dispatcher" under my sip_router/modules.
I usually start my ser with "/usr/local/sbin/serctl start".
Please let me know where I can get these files what you said.

Dear ALL:
I make the UA 1033 as busy status(pick up the phone and do nothing).
Then I try to make a call from 1011 to 1033. It should be redirect to a PSTN phone number( sip:0939749xxx@ser.xxx.net.tw ). I find it call failure and jump to failure_route[1], then swicth to route[3](for PSTN). But when I dump the package using ngrep. I can't find it try to connect PSTN trunk( xxx.xxx.190.243 is a CISCO 5300). I can find "SER: Connecting to PSTN....." message list at log file. Then the log display "SER: SIP Call On-Net section route(2)" message. It means that the call return to route[2] then failed. I guess that it stops or jump out route[3] after rewritehost(xxx.xxx.190.243).
Can anyone help me to trace the bug in the route[3]?
Best Regard Charles
