Hi all, In looking at Call Detail Recording, I ran into an issue where records were not being closed off in abandoned call scenarios. Upon closer investigation, I noticed that a call failure state event wasn't being generated in the Proxy because of an apparent change in the 408 Request Timeout SIP message. The criteria for generating a call failure state event in this scenario was to look at the "To tag" of the 408 Request Timemout message. If it was nil then the event was generated and otherwise it was not. In SipXecs 3.10.x, the abandoned scenario would have a nil "To tag" so the CDR record was correctly closed off. In 3.11.5, the "To tag" in this scenario is not nil and as a result the record is never closed off and appears in the active calls list for some time (around 8 hours). Deos anyone know if the change in the 408 message was intentional or is this a bug that should be reported. Looking at the RFC doesn't really give a clear answer (to me anyways) as to whether or not the ToTag should be present.
Thanks in advance Raymond
