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

[Nagorny, Dimitry]

John,

thanks for the quick reply, but I am not using the uac_replace_from() function. I checked routing and debug file for it.


Very Respectfully

/*Dimitry,
/*
/*Just an idea, but are you by any chance using the function
/*uac_replace_from()?
/*I ask because I have seen it corrupt the From header when it is called twice

/*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. (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.)
/*
/*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
/*
/*o   As well I couldn't find info about the abbreviation "HBH" or "HF"
/*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 files for more info.
/*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.
/*
/*Thanks in advance for any help I can get!
/*
/*Very Respectfully
/*Dimitry Nagorny
