<div><span>Hi,</span><br>
<span></span><br>
<span>Reinvites are in-dialog requests; they would only be sent within the</span><br>
<span>context of an established dialog (2xx response, end-to-end ACK, the</span><br>
<span>whole works).</span><br>
<span></span><br>
<span>Perhaps what you are referring to is not reinvites but retransmissions</span><br>
<span>of the initial INVITE?</span><br>
<span></span><br>
<span>If so, have a look at this option:</span><br>
<span></span><br>

<span></span><br>
<span>in concert with something like this:</span><br>
<span></span><br>
<span> failure_route[...] {</span><br>
<span> if(t_is_canceled())</span><br>
<span> exit;</span><br>
<span></span><br>
<span> # The scenario you're after.</span><br>
<span></span><br>
<span> if(t_branch_timeout()) {</span><br>
<span> t_reply("503", "Service Unavailable");</span><br>
<span> exit;</span><br>
<span> }</span><br>
<span> }</span><br>
