  • Added a pluggable keep-alive manager (focusing on NAT issues)
  • Allowed for non-busy, non-blocking wait handshakes with TLS
  • Included hostname in Call-ID
  • Added CNAME support to DNS resolution
  • Added v6 support to DNS resolution (both using DNS over v6 and supporting AAAA records
  • Added v6 ntop and pton support

Fixed Things[edit]

  • Fixed several memory leaks (TransactionState, SdpContents, others)
  • Fixed retransmit timers
  • Fixed several flaws in XMLCursor (simple xml parser)
  • Fixed mismatched cancel problem with 481 in TransactionState
  • Improved graceful shutdown logic in transaction layer
  • Generalized TimerQueue code
  • Fixed IPv6 handling errors througout code - tested IPv6 at SIPIts (both windows and *nix)
  • Fixed problem with TimerF producing a 408 to the TU when not in Calling state
  • Fixed problem with TransportSelector messing with route headers
  • Fixed bug in TransactionState where transmissions were being delivered to TU
  • Fixed assertion bug when trying to retransmit something that hasn't been transmitted yet
  • Fixed incompatibilities with earlier versions of windows in TransportSelector::determineSourceInterface
  • Fixed windows use of udp sendto
  • Corrected use of sip:/sips: and their effect on DNS lookups (3263)
  • Corrected use of resolver to do appropriate things for the currently available transports (per interface)
  • Fixed a SipFrag encoding problem
  • Added a Warning header to 503 responses
  • Improved robustness of QuotedDataParameter (will accept unquoted arguments and automatically add the needed quotes)
  • Fixed many S/MIME issues (and tested the results at SIPIts)
  • Throws when no Via appears in a message (instead of asserting)
  • Improved robustness of SDP parser (survives lack of final \r\n,survives lack of m lines, better e and p line parsing)
  • Reworked ThreadIf
  • Fixed a nasty bug in Condition::wait that was passing an incorrectly rounded value of tv_nsec into pthread_cond_timedwait and causing an assertion in some versions of linux
  • Removed unnecessary recomputations of 2543 transaction ids
  • Fixed socket leak in ares (close vs socketclose on windows)
  • Several fixes (particularly around USE_IPV6) to keep objects from changing size depending on stack configuration
  • Many fixes to TLS (tested at SIPITs) - In particular, fixed checks of subjectaltname/cname during TLS setup
