Subject: Re: [Sip-implementors] Malformed headers in SIP response
Hi,
In case of optional we may ignore, but for some cases they
are
mentioned as conditional. For eg: Replaces header.
Do we need to ignore the conditional cases also, say incase of Replaces
only
?
[ABN] RFC does not say (I am not sure about this fact) exactly how to
handle when particular parameter is in error (I mean to discard the
message as a whole or header only or only parameter...), for a good
stack, I feel just discard only that particular parameter (if the error
is in some parameter parsing) is a better option... if that information
is mandatory for that particular header then you cal assume that header
not been received...
