hi That is my understanding as well. But if that is the case then it should apply to Contact header as well when describing Capabilities using Feature parameters in Contact Header. But i'm not sure if it applies the same way. I had posted this question long ago but didnt get any comments on it. regards Mahesh ----- Original Message ----- From: "Christer Holmberg" <christer.holmberg@ericsson.com> To: <sip@ietf.org> Cc: "Paul Kyzivat" <pkyzivat@cisco.com> Sent: Wednesday, January 09, 2008 3:54 PM Subject: [Sip] Question on RFC3840/3841 Hi, Chapter 9 of RFC3840 says: "There are additional constraints on the usage of feature-param that cannot be represented in a BNF. There MUST only be one instance of any feature tag in feature-param." Chapter 10 of RFC3840 says: "Furthermore, there can only be one instance of any feature tag in feature-param." So, this means that the following is NOT allowed: Accept-Contact: *;myTag,myTag However, since an Accept-Contact header can contain multiple ac-values, each with its own sets of ac-parameters (including feature-params), the following should be allowed: Accept-Contact: *;myTag, *;myTag ...or: Accept-Contact: *;myTag Accept-Contact: *;myTag Correct?
