Hello,<br>
<br>
the functions from tm and tmx module work at transaction level -- if
the transaction was not created before (or the function doesn't
create the transaction), then they don't do much. The log messages
you gave indicated that the transaction was not found.<br>
<br>
In understood that you terminate the invite locally, not forward it
via sip anymore, so you need to create the transaction with the
dedicated function. Otherwise, t_relay() creates the transaction if
not created (for convenience).<br>
<br>
Cheers,<br>
Daniel<br>

<p class="MsoNormal"><span style="color:#1F497D">As suggested,
I’ve add the t_newtran() after the SIP INVITE and did work.
Now the responses are being send correctly (which is
great!), and in fact no need did notice that the 487
response is sent automatically, and thus no need to
explicitly generate one. <o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Curious to
understand why is that. I gathered that t_newtran() –
assuming this is the proper function – was used to create a
new transaction, let’s say if needed to generate a new SIP
INVITE req from the server (UAS) side. Why in that sense
would I need to create a “new” transaction?<o:p></o:p></span></p>

<br>
have you created the transaction for INVITE request?<br>
<br>
There is also a function t_cancel_callid() that could help
better than t_reply_callid().<br>
