Hi Carsten,<br><br>I tried that before but it's not what I really need. By saying that , when I added this function to my failure route then every call failure that happened (routing problem let's say) then immediately this GW was set to Inactive mode and I was not able to use it.<br>
<br>What I'm asking is to understand why Dispatcher module is sending calls to a GW in P state?<br><br>Thanks<br><br>Alex<br><br> <br><br><div class="gmail_quote">On Tue, Nov 16, 2010 at 3:54 PM, Carsten Bock <span dir="ltr"><<a href="mailto:lists@bock.info">lists@bock.info</a>></span> wrote:<br>

<br>
do you have a "ds_mark_dst("p")" in your failure route? This needs to<br>
be called "threshhold" times in order to set the gateway to probing...<br>
And please be aware of timeouts: If you have a Transaction-timeout of<br>
e.g. 60 seconds, then the failure-route would be executed after 60<br>
seconds and for this time the gateway would stay "active".<br>
