Hello All,

Question on an issue I am facing.  I have a case where I will reject a
re-INVITE under certain circumstances.  The scenario follows:

1) Receive: re-INVITE
2) Callback: nua_i_invite event (100 Trying)
3) Send: 403 Forbidden (nua_respond)
4) Callback: nua_i_state event nua_callstate_
   received (100 Trying)
5) Callback: nua_i_state event nua_callstate_
   ready (403 Forbidden)
6) Receive: ACK for response
7) Callback: nua_i_active event 403 Call Active

My question is: What is the best way to associate the asynchronous Callback
event in step 4) with the Callback event in step 2)?  That is, I want to
discard Callback event 4) in this scenario.

Is there a transaction handle available to make this association?  The only
handles I'm using now are the nh and hmagic (reported in the callback) which
are the same as the original INVITE in this scenario (not shown).

Best Regards,
Jerry
