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
