<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">This log message doesn't fit in with the rest of the messages in PJSIP land, and this can occur for non-header reasons. To copy/paste my own commit message:
If a response to an initial incoming INVITE results in a transport error
the INVITE transaction is removed from the INVITE session. Any attempts
to answer the INVITE session after this results in a crash as it requires
the INVITE transaction to exist. This change explicitly locks the dialog
and checks to ensure that the INVITE transaction exists before answering.

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">In addition, I'd steer clear of referring to struct fields in log messages since users won't have a clue what you are referring to. A somewhat higher-level way of stating the same thing would be:
"Cannot answer incoming call because there is no associated SIP transaction."</pre>

<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">When accidentally compiling asterisk against a rogue pjproject installation that had a slightly different definition pjsip_inv_session structure, the invite_tsx structure could appear null when answer() is called. This led to a crash because ast_sip_session_send_response would be called with an uninitialized packet.
This patch corrects the uninitialized packet to prevent the crash, and adds a diagnostic message to aid in discovering the cause of the problem (in this case, remove /usr/local/include/pj* to resolve conflicting structure).
