[Sip-implementors] SIP body with very long lines: a problem?

2010-09-01 Thread Iñaki Baz Castillo
Hi, in case a SIP message (i.e. MESSAGE text/plain) contains a very long line in the body (a long text with no line breaks), could it become a problem? Unfortunately I've seen some SIP ALG routers dropping SIP messages if they contain long lines in the message body, but I expect that is an issue i

Nitin, This is just a matter of personal opinion, but I think having that many codecs offered on an m= line is ridiculous. I'd like to hear somebody give justification for doing it :-) Seriously, how in the world can one build an interoperable system with this much clutter to dig through?

Thanks for your reply. I checked the RFC and noticed that it does not limit the codec #s in mline, but nor does it comment on infinite number of codecs support being mandatory. So could you please let me know whether it is mandatory to support them or not. Because if my SBC is not supporting this

This is valid, though I've never seen so many codecs on a single m= line. Who can practically deal with this? ;-) Paul From: sip-boun...@ietf.org [mailto:sip-boun...@ietf.org] On Behalf Of Nitin Kapoor Sent: Wednesday, September 01, 2010 9:51 AM To: sip-implementors@lists.cs.columbia.edu; s

It's allowed, though admittedly strange. None of the attributes for the second m= line have any significance. Paul > -Original Message- > From: sip-implementors-boun...@lists.cs.columbia.edu [mailto:sip- > implementors-boun...@lists.cs.columbia.edu] On Behalf Of > fred.madi...@gmx.net >

Dear All, I am facing the problem where one of source is sending bunch of RTP payload in "mline", and because of that my MSX is stripping 2 codec from that line, when its forwarding that OFFER to termination end. This is the "mline" which i am getting from source: *m=audio 6300 RTP/AVP 18 0 8 35
