<p class="MsoNormal">I’m trying to use OpenSIPS as a Border Controller between a PSTN and a FreeSWITCH. The PSTN is sending all SIP-messages through a SIP-trunk.<o:p></o:p></p>
<p class="MsoNormal">I got OpenSIPS working fine from PSTN through OpenSIPS to FreeSWITCH, but the other way around (from FS over OpenSIPS to PSTN), I’m getting an error message I can’t solve. (Info: There are NO phones registered with OpenSIPS or FreeSWITCH,
they are all on the PSTN, I need OpenSIPS only to guide traffic to either my FreeSWITCH mediaserver or tot he Aus @ PBX.)<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">As far as I can tell, when OpenSIPS opens up a new branch it is changing internally the headers from the incoming SIP-message from FreeSWITCH into a wrong format and after that it’s throwing two errors:<o:p></o:p></p>

I would very much appreciate it if somebody could give me, at least, a hint how I could fix the problem, because by now I googled these problems for three days now w/o a solution. I can’t attach the full debug, the mail list blocks the size of it (17KB…). I’ll
attach it to an answer.<o:p></o:p></p>
