The hex output Tony sent is actually much more useful

ngrep output you're asking for because it allows you to see the
problem--you can easily count the number of bytes in the payload.
The hex output may not be for humans to read, but it is for humans to count.
And it appears that he is right. I counted 200 bytes (2 + 12*16 + 6)
in the payload while the Content-Length header says 201.
If you read the email
again, then you may get what I wanted to say, I
asked for pcap tar.gz or ngrep.
Pcap is better to import in wireshark or even ngrep where you can
analyze thoroughly - tar.gz is recommended for pcap otherwise some email
clients do text encoding and the format gets broken.
Ngrep is easier to read directly and discover if the sdp is altered by
the proxy or is the one from them the phone.
Now, if it is easier for you to count hex codes by hart in a combined
content, then it is fine. For me is easier to get the body in text
format and use wc tool to count.
Cheers,
Daniel

Never ever send private emails - they will be
discarded, keep the mailing
list cc-ed.
Iptel org is running SIP Express Router 3.1. Take a ngrep of the traffic and
send it here, the hexa codes you send are not for humans to read, like we
are here on mailing lists. Otherwise make a tar.gz of pcap file. SER changes
content length only if it is an update to sdp (for nat traversal), otherwise
is the one set by the other phone.

Thanks Daniel,
fyi, the Content-Length doesn't match the actual length in the invite ok
returned from iptel.org (213.192.59.75), and the same situation also occurs
from ekiga.net.
libosip2 interprets the rfc as saying that this 'should' be correct. (and I
buy this!).
it looks like an openser (opensips?) quirk.
anyway, I have put in code locally to fixup the Content-Length.
Thanks,
Tony.

http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users Hello,
you claim that contact header is malformed or libosip2 has issues in
parsing a good content header?
In case of first option, can you tell what it believes is wrong. Your
message is hard to follow since is not clear text, next time send only the
text part.
For the second option, you have to approach libosip2 support forums.
Cheers,
Daniel

Hi,
Not sure how to provide this info (or even if anybody cares), but libosip2
parser objects to incorrect (short) Content-Length from iptel.org.
Regards,
Tony.
