<div>Hello,</div>
<div><br>
</div>
<div>I have an issue with the behavior
of ds_select_dst() method in case of
using algorithm 8 (dispatch based on
priority). In case both destinations
are available, they are used
alternatively, instead of always
using the one with the highest
priority.</div>
<div><br>
</div>
<div>By searching through the mailing
list I found that the lower the
priority number, the higher the
priority (1 is first, 2 is second,
etc.).</div>
<div>Based on this, I set the
following in dispatcher.list:</div>
<div><span class="m_-3706102619459100822m_8398944217705792573m_-1942699592390341046gmail-Apple-tab-span" style="white-space:pre-wrap"> </span>7

<div><span class="m_-3706102619459100822m_8398944217705792573m_-1942699592390341046gmail-Apple-tab-span" style="white-space:pre-wrap"> </span>7

target="_blank">10.126.55.51:5060</a>;transpor<wbr>t=sctp
9 2</div>
<div><br>
</div>
<div>After running "kamcmd
dispatcher.reload" and "kamcmd
dispatcher.list", I have the
confirmation that the priorities are
correctly set:</div>
<div> SET: {</div>
<div> ID: 7</div>
<div> TARGETS:
{</div>
<div>
DEST: {</div>

<div>

<div> }</div>
<div> }</div>
<div> }</div>
<div><br>
</div>
<div>The dispatcher settings from
kamailio.cfg is the following:</div>

"sock_avp", "$avp(AVP_SOCK)")</div>
<div><br>
</div>
<div>And the code which should do the
displatch is the following:</div>
<div><br>
</div>
<div> if (ds_is_from_list(7, 3,
"$ru")) {</div>
<div> remove_hf("Route");</div>
<div> if(!ds_select_dst("7",
"8")) {</div>
<div> send_reply("404", "No
destination");</div>
<div> exit;</div>
<div> }</div>
<div> }</div>
<div><br>
</div>
<div>With the settings above, I was
expecting to always have the
messages delivered to 10.126.54.51.
Instead, they are dispathed to
10.126.54.51 and 10.126.55.51
alternatively.</div>
<div><br>
</div>
<div>Thanks a lot,</div>
<div>Cristian</div>
