  1. SIP Torture Tests Robert Sparks dynamicsoft SIPPING – IETF58

  2. Significant Rewrite • Removed tests based on deprecated 2543 features (such as absolute times in Expires) • Added tests focusing on 3261 • Increased rigor on tests of escaping, non-ascii UTF-8, long or out-of-range values, and protocol extension points • Added detail to discussion of each message • SDP tests have been removed (to appear in an mmusic sdp-torture test draft) • Conformed to ID-Nits

  3. Reducing Ambiguity • Introduced new markup • allOneLine • hex • repeat • Added bit-accurate archive • Base64 encoded zip file of the real messages • Filename indicated in the “Message Details” line of each example.

  4. Created ReusableTools • I-D encoded and bit-accurate messages are built from a common source. • Content-Length is automatically calculated (when requested). • Designed to integrate easily with xml2rfc.

  7. Open Issues • There are some production bugs • Message filenames didn’t make it into the draft as intended • <hex> expansions in the bit-accurate files aren’t accurate • All messages are new or heavily edited and need careful review

  8. Open Issues • There are questions about specific messages in the open-issues section of the draft. These need list attention. One is reasonable to discuss here: • Are the long-value examples in 3.1.1.7 long enough?

  9. Future Work • Should the messages be normalized to support automation? • Reusing common names for the initiator and recipient • Making some identifier (Call-ID) unique to assist with debugging
