<tt>Hi Samuel,<br>
<br>
You should do like:<br>
<br>
</tt> $var(i) = 0;<br>
while ($var(i) < $(avp(callee_fork){param.count})) {<br>
$avp(callee_uri) =
$(avp(callee_fork){param.valueat,$var(i)});<br>
if ($var(i)!=0)<br>
append_branch();<br>
$ru = $avp(callee_uri);<br>
$avp(callee_username) = $rU;<br>
$avp(callee_realm) = $rd;<br>
setbflag(27);<br>
lookup("location","mb");<br>
setflag(9);<br>
$var(i) = $var(i) + 1;<br>
}<br>
<tt><br>
the idea is, before overwritting the RURI, push the existing
content as a new branch - at the first step you do not have to do
it as originally (before the loop) the RURI content is not to be
kept.<br>
<br>

I tried several things since, I understood that :<br>
$branch = $ru;<br>
append_branch();<br>
makes 2 branches, so everything is duplicated.<br clear="all">
<div><br>
I removed $branch = $ru; it's better now, but I had again 1
duplicated branch : the 0 and the last one in the loop.<br>
<br>
This worked for me :<br>
$var(j) = $(avp(callee_fork){param.count}) - 1;<br>
if ($var(i) < $var(j)) {<br>
append_branch();<br>
}<br>
<br>
then, what I did mistake, is that I've to do manipulations into
my loop and set up branch flags accordingly.<br>
so, I've now a huge loop process :(<br>
<br>
There are 2 little things I don't understand yet :<br>
<br>
1/ in the branch route where I send the result of the loop :<br>
branch_route[1] {<br>
xlog("L_NOTICE","br1: engage branch $T_branch_idx to $ru");<br>
...<br>
}<br>
<br>
I got this ERROR line for each branch :<br>
opensips[15295]: ERROR:tm:pv_get_tm_ruri: BUG: _tm_branch_index
greater than nr_of_outgoings<br>
<br>
2/ accounting<br>
<br>
I've really something clean for the INVITE using Sip-Leg-Dst /
Sip-Leg-Src, each R-URI branch is correctly added.<br>
but ... nothing in the BYE or CANCEL (independently of the
direction of the request).<br>
I can not know which branch answered, and nothing in the
accounting logs that indicates which one I've to account - I've
only the first request URI of the INVITE, and no information
about the callee behind the hunting group that I've to use.<br>
<br>
How can I get that ?<br>
<br>
Thank you,<br>
<br>

<div bgcolor="#ffffff" text="#000000"> <tt>Hi Samuel,<br>
<br>
It is not clear from your script snapshots where you are
supposed to set the bflags 11 and 28.<br>
<br>
The idea is that you create all the additional branches
(as normally you have the RURI - mandatory - plus some
optional additional branches) in that "while" loop. In the
request route you are doing changes only over the RURI
(and not over the additional branches). Accessing the
already created branches can be done via the $branch[]
variables only.<br>

<div class="h5">Hello,<br>
<br>
I'm looking for explanations about parallel forking
and branch flags.<br>
I'm deeply annoyed by this feature ...<br>
<br>
I need to set up different parameters (like rtpproxy,
from display, accounting, ...) per contact.<br>
<br>
actually, I retrieve a list of contact using an AVP,
in the format that the core function "while" can use.<br>
<br>
It's working fine when there are no manipulation or no
(new) callee parameters to add :<br>
<br>
route[FORK] {<br>
xlog("L_NOTICE","parallel fork requested");<br>
$var(i) = 0;<br>
while ($var(i) <
$(avp(callee_fork){param.count})) {<br>
$avp(callee_uri) =
$(avp(callee_fork){param.valueat,$var(i)});<br>
$ru = $avp(callee_uri);<br>
$avp(callee_username) = $rU;<br>
$avp(callee_realm) = $rd;<br>
setbflag(27);<br>
lookup("location","mb");<br>
setflag(9);<br>
$branch = $ru;<br>
append_branch();<br>
$var(i) = $var(i) + 1;<br>
}<br>
route(RTPPROXY); # rtp proxy set = bflag 11<br>
route(ACCOUNTING); # accounting using $rU. $ru,
...<br>
route(RELAY);<br>
exit;<br>
}<br>
route[RELAY] {<br>
t_on_branch("1");<br>
t_on_reply("1");<br>
t_on_failure("1");<br>
t_relay("0x01");<br>
exit;<br>
}<br>
<br>
At this point, I'm totally lost :<br>
I have to check if a callee need to use rtpproxy, set
up the accounting, change the "from" display based on
the destination (PSTN vs. local subscriber), and so
on.<br>
Everything failed, the parameters are always global
(based on the branch("0")) even if I use branch flag,
script flag, or do anything into the branch route.<br>
<br>
branch_route[1] {<br>
xlog("L_NOTICE","br1: engage branch $T_branch_idx
with R-URI: $T_ruri ($ru)");<br>
xlog("L_NOTICE","br1: dest set: $ds / dest uri:
$du");<br>
if (isbflagset(11)) {<br>
xlog("L_NOTICE","br1: rtp proxy set to
\"cr\"");<br>
engage_rtp_proxy("cr");<br>
}<br>
if (isbflagset(28)) {<br>
uac_replace_from("$avp(caller_cli)","");<br>
}<br>
}<br>
}<br>
<br>
did I missed something ???<br>
<br>
Thanks to light my fire, I really need it ...<br>
<br>
