Hello,<br>

try without restore_mode auto if you want that restore_dlg to be 1.<br>

</div>
<div>I think the problem is in registering a
function restore_uris_reply() in callbacks in functions (both
in replace.c of uac module)</div>
<div>* void rr_checker(struct sip_msg *msg, str *r_param, void
*cb_param)</div>
<div>* static void replace_callback(struct dlg_cell *dlg, int
type, struct dlg_cb_params *_params)</div>
<div><br>
</div>
<div>Both of these callbacks are registered for BYE and ACK
requests (INVITE request is using different callback),
therefore running restore_uri_reply() twice.</div>
<div>For testing purposes after I have removed the callback in
rr_checker and recompile the uac module, To and From headers
were OK.</div>
<div><br>
</div>
<div>In my configuration I'm calling uac_replace_to in RELAY
route:</div>
<div>
<div>route[RELAY]</div>
<div>{</div>
<div><br>
</div>
<div> if ( !has_totag() ) {<br>
</div>
<div> dlg_manage();</div>
<div> uac_replace_to("$ru"); </div>
<div> }</div>
<div><br>
</div>
<div> if (!t_relay())</div>
<div> {</div>
<div> sl_reply_error();</div>
<div> }</div>
<div>}</div>
</div>
<div><br>
</div>
<div>So I think there is a bug in uac module, when one function
is registered twice in callbacks for NON-INVITE requests. </div>
<div><br>
</div>
<div>Or is there a problem with my configuration script?</div>
<div><br>
</div>
<div>Can anyone point me to the direction how to solve this
issue?</div>
<div><br>
</div>
<div>Thank you</div>
