<p><span>after try timer times out, you will get back the original invite in failure route, where you can send it actual destination to send it again to "go-around" trip to impossible destination. Of course while this is happening, you should send fake "180 Ringing" message to caller so s/he won't suffer from dead-air silence.</span></p>

<div>Hi,</div>
<div> </div>
<div>
<div>I am looking for some idea for the following use case:</div>
<div> </div>
<div>1. opensips receives initial INVITE from the caller.<br/>
2. finds that the callee is not registered.<br/>
3. sends a non-SIP message to the callee device to register.<br/>
4. callee registers and opensips routes the INVITE to the callee contact uri.</div>
<div> </div>
<div>The calle device may take around 10 seconds to register back (after sending the non-SIP message).<br/>
Obvisously, it is not advisable to wait in the opensips.cfg for such a long time.</div>
<div>Can anyone suggest a smart way to handle this?</div>
<div> </div>
</div>
<div>Thanks<br/>
-Gary</div>
