Hi, In ETSI TS 102 027-2 V4.1.1 (2006-07), test case SIP_CC_PR_TR_SE_V_014, it mentioned :
<Quote> TPId: SIP_CC_PR_TR_SE_V_014 Status: PICS: A.77/3.2 Ref: RFC 3261 [1] sections 17.2.2 and 17.2.3. Purpose: Ensure that the IUT in a server BYE Proceeding state, on receipt of a BYE request, including a Via header set with a different branch parameter without the magic cookie "z9hG4bK" but with the Request-URI, To tag, From tag, Call-ID, CSeq and top Via header identical as in the first BYE request, repeats its last response. </Quote> But as per Via header comparison rule defined in RFC3261 20.42 Via, <Quote> Two Via header fields are equal if their sent-protocol and sent-by fields are equal, both have the same set of parameters, and the values of all parameters are equal. </Quote> So that one Via with different branch value, so second BYE with a different branch parameter will never the transaction create by the first BYE, so it shall not repeats its last response. so the test case is wrong. Does I miss sth?
