append_branch() works in 4.0 if you need to add additional branches.<br>
<br>
Look at default config file to see an example of using branch_route.<br>

<div dir="ltr">Hi Daniel,<br>
<br>
<div>Sorry to bug you just wondered if had a chance to consider
the branching question?</div>
<div><br>
</div>
<div>Main thing is does append_branch work on 4.0 ?</div>
<div><br>
</div>
<div>And also the best way to implement branch routes?</div>

<div dir="ltr">Hello,
<div><br>
</div>
<div>I am getting there!</div>
<div><br>
</div>
<div>I am not using a branch routing block at present, I am
doing modifications using values I pull from the location
table.</div>
<div><br>
</div>
<div>So my question may be slightly different but very much
branch related.</div>
<div><br>
</div>
<div>
<div>So I have two contacts;</div>
<div><br>
</div>
<div><br>
</div>
<div>Contact::
<a class="moz-txt-link-rfc2396E" href="sip:1009@213.123.211.158:15060;transport=udp;registering_acc=91_208_141_34"><sip:1009@213.123.211.158:15060;transport=udp;registering_acc=91_208_141_34></a>;q=;expires=60;flags=0x0;cflags=0x0;state=1;socket=<a class="moz-txt-link-rfc2396E" href="udp:xx.xx.xx.xx:5060"><udp:xx.xx.xx.xx:5060></a>;methods=0xFFFFFFFF;user_agent=<Contact1>;reg-id=0</div>
<div>Contact::
<a class="moz-txt-link-rfc2396E" href="sip:1009@213.123.211.158:5061;transport=udp"><sip:1009@213.123.211.158:5061;transport=udp></a>;q=;expires=3191;flags=0x0;cflags=0xC0;state=1;socket=<a class="moz-txt-link-rfc2396E" href="udp:xx.xx.xx.xx:5060"><udp:xx.xx.xx.xx:5060></a>;methods=0xFFFFFFFF;received=<a class="moz-txt-link-rfc2396E" href="sip:213.123.211.158:49827"><sip:213.123.211.158:49827></a>;user_agent=<Contact2>;+sip.instance=<urn:uuid:00000000-0000-0000-0000-58bfea20a6bd>;reg-id=0</div>
<div><br>
</div>
<div>Then using reg_fetch_contacts I get for each
registered contact;</div>
<div><br>
</div>
<div> xlog("callee=>user_agent:
$(ulc(callee=>user_agent)[$var(i)])\n");</div>
<div> xlog("callee=>received:
$(ulc(callee=>received)[$var(i)])\n");</div>
<div> xlog("callee=>addr1:
$(ulc(callee=>addr)[$var(i)])\n");</div>
<div><br>
</div>
<div>And define some variables as a result for each
contact;</div>
<div><br>
</div>
<div> $var(ua1) =
$(ulc(callee=>user_agent)[$var(i)]);</div>
<div> $var(ua1add) =
$(ulc(callee=>received)[$var(i)]);</div>
<div> $var(ua1aor) = $(ulc(callee=>addr)[$var(i)]);</div>
<div><br>
</div>
<div><br>
</div>
<div>I then use these to set $du and $ru in the main
routing, I do this for contact2 above, so I send to the
recieved port (49827), identifying this by user agent
type.</div>
<div><br>
</div>
<div>This works fine however branch[0] was sending an
INVITE TO <a class="moz-txt-link-abbreviated" href="mailto:1009@213.123.211.158:5061">1009@213.123.211.158:5061</a>, contact2 also, and
not contact1 (port 15060), so I have added;</div>
<div><br>
</div>
<div>$(branch(dst_uri)[0]) = $var(ua1aor);</div>
<div><br>
</div>
<div>So I now get parallel forking as follows;</div>
<div><br>
</div>
<div>INVITE <a class="moz-txt-link-freetext" href="sip:1009-@213.123.211.158:49827">sip:1009-@213.123.211.158:49827</a> < This
is what I want, for Contact2</div>
<div>INVITE <a class="moz-txt-link-freetext" href="sip:1009-@213.123.211.158:15060">sip:1009-@213.123.211.158:15060</a> < Again
routes to Contact1 after modifiying the branch
parameter.</div>
<div>INVITE <a class="moz-txt-link-freetext" href="sip:1009-@213.123.211.158:5061">sip:1009-@213.123.211.158:5061</a> < Still
sends out original branch value.</div>
<div><br>
</div>
<div><br>
</div>
<div>And can see from debug, my branch [0] is modifed, but
branch [1] is also created;</div>
<div><br>
</div>
<div>new branch [0] to <a class="moz-txt-link-freetext" href="sip:1009@213.123.211.158:49827">sip:1009@213.123.211.158:49827</a></div>
<div>new branch [1] to <a class="moz-txt-link-freetext" href="sip:1009@213.123.211.158:5061">sip:1009@213.123.211.158:5061</a></div>
<div><br>
</div>
<div>So I now have 3 invites for 2 devices.</div>
<div><br>
</div>
<div>Whats the best approach to clean this up or implement
in the first place, my main question is probably around
branch modification/control.</div>
<div><br>
</div>
<div>Thanks, sorry for long question.</div>
<div><br>

Hello,<br>
<br>
are you using a branch_route block?<br>
<br>
Cheers,<br>

<div>Hi Guys,</div>
<div><br>
</div>
<div>Following on from my initial query, I have
indexing working for reg_fetch_contacts, however
now I am </div>
<div>having issues with branching.</div>
<div><br>
</div>
<div>First, is append_branches() still applicable to
kamailio 4.0.6 ? As when I use its not
recognised.</div>
<div><br>
</div>
<div>Also I have two contacts registered, contact 0
and contact 1.</div>
<div><br>
</div>
<div>Contact 0 was registered first, then contact 1.</div>
<div><br>
</div>
<div>Now I perform manipulation on the main branch
after identifying the user agent for contact 1,
and the main</div>
<div>branch request is sent out as I wish, this uses
branch [0] when running debug to the $ru/$du I
have modified.</div>
<div><br>
</div>
<div>However with branch [1] this isnt modified
which is fine, but uses the contact AOR from
Contact 1 and not Contact 0.</div>
<div><br>
</div>
<div>Is this normal behaviour and I just need to
improve my logic?</div>
<div><br>
</div>
<div>Any advise on parallel branching where you
extract certain credentials from location table,
then as a result</div>
<div>manipulate the $ru and $du as a result, but
dont affect any other multiple registrations that
would be great!</div>
<div><br>
</div>
<div>Many thanks</div>

<div dir="ltr">Hi Guys,
<div><br>
</div>
<div>I was wondering if anyone could help?</div>
<div><br>
</div>
<div>I am currently using reg_fetch_contacts
to manipulate signaling based on the user
agent device being used, therefore I use
the result of;</div>
<div><br>
</div>
<div>
<div>if(reg_fetch_contacts("location",
"$ru", "callee"))</div>
<div>{</div>
<div><span style="font-size:12pt;">
xlog("callee=>user_agent
$ulc(callee=>user_agent)\n");</span></div>
<div><span style="font-size:12pt;">}</span></div>
<div><span style="font-size:12pt;"><br>
</span></div>
<div><span style="font-size:12pt;"><br>
</span></div>
<div><span style="font-size:12pt;">I then
use $ulc(callee=>user_agent) to
make routing decisions.</span></div>
</div>
<div><span style="font-size:12pt;"><br>
</span></div>
<div><span style="font-size:12pt;">This
seems to only return the user-agent
device being used for the first
registration at that AOR, as I have two
devices registered, a Cisco, and a jitsi
client, and it only returns the
user_agent of the jitsi client I
registered first.</span></div>
<div><span style="font-size:12pt;"><br>
</span></div>
<div><span style="font-size:12pt;">Is it
possible to return the user agents of
all the devices registered against an
AOR so I can manage decisions
accordingly?</span></div>
<div><span style="font-size:12pt;"><br>
</span></div>
<div><span style="font-size:12pt;">Many
thanks</span></div>
