Hello,<BR>
uac_req_send() is able to send only initial requests (with follow
up on auth challenge). It doesn't expose the ability to send
requests within a dialog -- the functions exist in c (tm module),
but not availble in config.<BR>
On the other hand, there should be a mi/rpc command exported by
tm module that allows that -- it may be possible to do it from
config file via jsonrpc-s module.<BR>
Cheers,<br>
Daniel<br>

<pre style="white-space:pre-wrap;">Is it still the case that when using uac_req_send, you cant send withing a specific dialog?</pre>

</i>sending a new request inside a dialog is not possible with
uac_req_send(). It is not easy over all because you change the sequence
order (CSeq value). Practically, you need to track how many requests you
sent from the middle to update (and restore in reply) when caller or
callee sends a new request.
dialog module can track changes in CSeq for requests sent to callee,
being used now for authentication of INVITE to another provider, when
Kamailio adds the credentials. But for more you would need to extend the
dialog module.
I just need to send a SIP info within an established dialog to stop some function up stream, so wondered if this is still a blocker?</pre>
