Betreff: [OpenSIPS-Users] OpenSIPS error Malformed Header/failed to generate a 
HBH ACK

Good afternoon Ladies and Gentlemen,

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.
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.

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:

-          ERROR:tm:send_ack: failed to generate a HBH ACK if key HFs in reply 
missing
ERROR:tm:reply_received: failed to send ACK (local=no)

o   Here I looked at the relevant code but I can't tell what it is trying to do 
in the transaction module
Additionally this piece of info:

-          ... SIP/2.0 400 Bad Request..Warning: 399 192.168.1.30 "Malformed 
headers : From " ...

o   From this somehow I found out that it's missing the ":" after From


Please see the attached config, routing logic, oopensips-errorlog and the 
sip-trace.
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.

Thanks in advance for any help I can get!


Very Respectfully
