I think the hole case is typical example of: "be liberal on what you receive,
but be strict on what you send". Thus IMO both implementations, the gateway
and the proxy, should be fixed.
Jiri: sure you can refer to the generic extension. That allows any header with
any value in a SIP message. But then you can not count on the rules any more
which apply only to the non-generic headers (here how to process the MF
header). Otherwise you would be allowed to put any content into any known
header.
But I agree that the RFC BNF should be extended to allow WS also at the end of
a line.
Sorry but I do not agree to implement a RFC compliance test which is IMHO not
covered by the RFC (yet).

The BNF in RFC3261 is actually ambiguous. As you may
see,
the extension header spec which matches Max-forwads too is
more explicit about use of LWS.
header-name = token
header-value = *(TEXT-UTF8char / UTF8-CONT / LWS)
I think this is a pefect case against a UAS for the SIP Forum testing
suite. (Nils on cc)

Hello,
I think the white space is not legal in 3261. Please take a look at the

Hi,
One of the headers in the posting to the SERusers mailing
list is:
Max-Forwards: 8 .
According to RFC3261 Max-Forwards is defined as:
Max-Forwards = "Max-Forwards" HCOLON 1*DIGIT
and DIGIT (from RFC2234) is:
DIGIT = "0" / "1" / "2" / "3" /
"4" / "5" / "6" /
"7" / "8" / "9"
So, you can have a space between the colon and the first digit
but you're not allowed any spaces after or between any digits
and you're certainly not allowed a '.' character.
Regards,
Attila
