Error description
Issue with the Session Initiation Protocol (SIP) stack embedded in WebSphere Application Server v6.1.0.11 The problem is related to the interpretation of escape character '%' in the branch token. As indicated in the following trace, a branch token sent containing '%50' that has been returned in the 200 OK as 'P'. SUBSCRIBE sip:195.212.190.153:5060 SIP/2.0 Via: SIP/2.0/UDP 192.168.201.9:1118;branch=z9hG4bKQGT%50 CSeq: 4 SUBSCRIBE From: <sip:[email protected]>;tag=BAwYnSxlU0 To: <sip:[email protected]>;tag=8381863920113239_local.1234187431851_1688 _5210 Call-ID: T5LQwBUKsS-0001 Contact: <sip:[email protected]:1118;transport=UDP> Max-Forwards: 70 Content-Length: 0 Expires: 3600 Event: presence Supported: eventlist Accept: application/pidf+xml,application/rlmi+xml,multipart/related SIP/2.0 200 OK Require: eventlist Call-ID: T5LQwBUKsS-0001 CSeq: 4 SUBSCRIBE From: <sip:[email protected]>;tag=BAwYnSxlU0 To: <sip:[email protected]>;tag=8381863920113239_local.1234187431851_1688 _5210 Via: SIP/2.0/UDP 192.168.201.9:1118;branch=z9hG4bKQGTP Contact: <sip:195.212.190.153:5060;transport=udp> Expires: 3600 Content-Length: 0 According to BNF in the RFC, and the escape character '%' is explicitly indicated as allowed in a token. via-branch = "branch" EQUAL token token = 1*(alphanum / "-" / "." / "!" / "%" / "*" / "_" / "+" / "`" / "'" / "~" ) When characters need to be escaped, the BNF indicate it explicitely, like in the following example password = *( unreserved / escaped / "&" / "=" / "+" / "$" / "," )

Problem summary
**************************************************************** * USERS AFFECTED: Session Initiation Protocol (SIP) users * * of IBM WebSphere Application Server V6.1 * * and V7.0 * **************************************************************** * PROBLEM DESCRIPTION: The parser attempts to decode * * parameters in the Via header, * * contrary to the definition of the Via * * header in RFC 3261. * **************************************************************** * RECOMMENDATION: * **************************************************************** When the container receives a message from the transport, it parses the message, and then passes the message object to the application. While parsing each parameter in the Via header field value, it attempts to decode escaped characters in the parameter. This contradicts RFC 3261 (25.1) which specifies that Via header parameters do not contain escaped characters.
Problem conclusion
The bug was fixed in the SIP (Session Initiation Protocol) container code. With this fix, the container no longer attempts to decode escaped characters in Via parameters. The fix for this APAR is currently targeted for inclusion in fix packs 6.1.0.25 and 7.0.0.5.
