Error description
Large timestamps in a Session Initiation Protocol (SIP) request can cause problems due to the format of the timestamp. When large timestamps are use, SIP does not write out the Timestamp header correctly.

Problem summary
**************************************************************** * USERS AFFECTED: Session Initiation Protocol (SIP) users * * of IBM WebSphere Application Server V6.1 * * and V7.0 * **************************************************************** * PROBLEM DESCRIPTION: Incorrect Timestamp header field * * syntax in messages sent by the * * application server. * **************************************************************** * RECOMMENDATION: * **************************************************************** The problem occurs when the application server sends a SIP message, and the message contains a Timestamp header field. The Timestamp value is written in scientific notation instead of the ordinary decimal notation. For example, the server receives an INVITE request with a standard Timestamp header field: INVITE sip:example.com SIP/2.0 Timestamp: 1262304000000 ... The server replies with a Timestamp header field such as this. The numeric value is the same, but the format is different: SIP/2.0 100 Trying Timestamp: 1.262304E12 ... Scientific notation is not compliant with the standard syntax, as defined in section 25.1 of RFC 3261.
Problem conclusion
The problem is fixed in the SIP (Session Initiation Protocol) container code. With this fix, the value of the Timestamp header field is written in ordinary decimal notation only. The fix for this APAR is currently targeted for inclusion in fix pack 1.0.0.5.
