<p class="MsoNormal"><span lang="NL"><o:p> </o:p></span></p>
<p class="MsoNormal">I’m trying to use multiple destination sets
which may include the same destination.<o:p></o:p></p>
<p class="MsoNormal">For instance: <o:p></o:p></p>
<p class="MsoNormal">SET ID: 1<o:p></o:p></p>
<p class="MsoNormal"><a href="sip:10.0.0.1:5060"
moz-do-not-send="true">sip:10.0.0.1:5060</a><o:p></o:p></p>
<p class="MsoNormal"><a href="sip:10.0.0.2:5060"
moz-do-not-send="true">sip:10.0.0.2:5060</a><o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">SET ID: 2<o:p></o:p></p>
<p class="MsoNormal"><a href="sip:10.0.0.1:5060"
moz-do-not-send="true">sip:10.0.0.1:5060</a><o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Whenever a new SIP INVITE is sent to the
Kamailio instance it will use SET ID 1. If then for some
reason this call attempt fails, failure_route will trigger and
SET ID 2 will be used. At first glance this might not make
any sense, but there is some business logic behind this, but
it’s not relevant for this case.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">For some reason, the dst_avp variable still
contains the destinations of SET ID 1 in failure_route.<o:p></o:p></p>
<p class="MsoNormal">Is there a built-in way to reset this
variable for every call to ds_select_domain(), such that only
the destinations of passed SET ID will be loaded into the avp?<o:p></o:p></p>
<p class="MsoNormal">I tried setting the avp to $null before
calling ds_select_domain, but that had some undesirable
effects.

</p>
<p>If ds_next_*() returns false, then it should be no avp with a
destination address from dispatcher? Have you printed the avps and
see how amby are? Also, what where those effects?</p>

<p class="MsoNormal">The reason I’m asking this is the
destinations the call is being sent to are Freeswitch
instances, which will return a 482 Request Merged when the
same INVITE is sent to the same Freeswitch within 4 seconds
(default T4 timer).
<o:p></o:p></p>
<p class="MsoNormal">I’m trying to match the previously selected
destination in failure_route with the next destination and
skip if they’re the same, or stop processing when they are the
same and no more destinations are available.
<o:p></o:p></p>
<p class="MsoNormal">I know I can mess with the T4 timer in
Freeswitch and perhaps even sleep in failure route to deal
with the 482 failure, but I rather fix this in a normal way.<o:p></o:p></p>
