[OpenSIPS-Users] drouting module with append_branch() and q-values
I'm trying to get OpenSIPS to act as a REDIRECT server and have run into a
couple issues. I'm using the drouting module to do lookups. Essentially, a
dialed number could have potentially several routes, I want to return a 300
with these routes in the Contact header. Please tell me if this is foolish
and/or there are better methods.
I'm running release version 1.6.4-2-notls.
With that, I've configured the following in my script:
if (do_routing("1","2"))
{
if ($avp(s:dr_rules_attrs) == "2")
{
xlog("L_INFO","After 1, ds is $ds\n");
$var(x) = 2;
while (use_next_gw())
{
append_branch();
xlog("L_INFO","After $var(x), ds is $ds\n");
$var(x) = $var(x) + 1;
}
}
xlog("L_INFO","Destination set is $ds\n");
}
My relevant debug output is:
After 1, ds is Contact: sip:15552345678@1.1.1.1
After 2, ds is Contact: *sip:2215552345678@2.2.2.2,
sip:2215552345678@2.2.2.2*
After 3, ds is Contact: *sip:5552345678@3.3.3.3*, sip:2215552345678@2.2.2.2,
*sip:5552345678@3.3.3.3*
After 4, ds is Contact: *sip:15552345678@5.5.5.5*, sip:2215552345678@2.2.2.2,
sip:5552345678@3.3.3.3, *sip:15552345678@5.5.5.5*
After 5, ds is Contact: *sip:4415552345678@4.4.4.4*,
sip:2215552345678@2.2.2.2, sip:5552345678@3.3.3.3, sip:15552345678@5.5.5.5,
*sip:4415552345678@4.4.4.4*
It seems that append_branch() deletes the first entry in the destination set
before adding the current RURI to the beginning and end. Is there an easier
or more predictable way to write to the destination set?
Also, it seems the append_branch() function will not take variables or avps
as parameters. Is there a known way of setting different q-values as a
destination set is generated? The below obviously doesn't work but should
explain what I'm looking for:
var(q) = 90;
while (use_next_branch())
{
append_branch("$ru","$var(q)");
$var(q) = $var(q) - 10;
}
Thanks,
Ryan

Re: [OpenSIPS-Users] drouting module with append_branch() and q-values
Hi thrillerbe,
I think that if you only want to build the list of selected
destinations, you can just call use_next_gw and add the uri in RURI to a
destination string ( because use_next_gw sets the RURI to the
destination-
http://www.opensips.org/html/docs/modules/devel/drouting.html#id251519).
It would be something like this:
if (do_routing("1","2"))
{
if ($avp(s:dr_rules_attrs) == "2")
{
xlog("L_INFO","After 1, ds is $ru\n");
$var(x) = 2;
$var(ds) = $ru;
while (use_next_gw())
{
$var(ds) = $var(ds) + "," + $ru;
xlog("L_INFO","After $var(x), ds is $var(ds)\n");
$var(x) = $var(x) + 1;
}
}
xlog("L_INFO","Destination set is $var(ds)\n");
}

Re: [OpenSIPS-Users] drouting module with append_branch() and q-values
Hi,
Another tricks:
1) you can read the pending destinations directly from AVPs, without
calling the "use_next_gw()" function. See:
http://www.opensips.org/html/docs/modules/1.6.x/drouting.html#id293166
2) as append_branch() does not accept variables as params, use the
"$branch" variable to write into:
http://www.opensips.org/Resources/DocsCoreVar16#toc15
like:
$branch = $var(x) ; #add a new SIP URI as extra branch
$(branch(q)[-1]) = 10 ; # set Q val for the last added brach

Bogdan

Bogdan,
When I configure:

$(branch(q)[0]) = 100;
xlog("L_INFO","branch 0 = $(branch(uri)[0]) with q-value
$(branch(q)[0])\n");
I get this debug:

Re: [OpenSIPS-Users] drouting module with append_branch() and q-values
Bogdan,
Nevermind on that issue; I neglected to notice that I had to create the
branch with append_branch() before setting anything.
Thanks for the help.

It seems that append_branch() deletes the first entry in the
destination set before adding the current RURI to the beginning and end. Is
there an easier or more predictable way to write to the destination set?
Also, it seems the append_branch() function will not take variables or
avps as parameters. Is there a known way of setting different q-values as a
destination set is generated? The below obviously doesn't work but should
explain what I'm looking for:
var(q) = 90;
while (use_next_branch())
{
append_branch("$ru","$var(q)");
$var(q)
Re: [OpenSIPS-Users] drouting module with append_branch() and q-values
Hopefully my last question:
Using append_branch() and $branch allows me to add all destinations as
branches with q-values. However, I am unable to remove/edit the initial
entry in $ds as set by do_routing():
Contact: *sip:15552345678@1.1.1.1, *;q=1, <
sip:2215552345678@2.2.2.2>;q=0.9, ;q=0.85, <
sip:15552345678@5.5.5.5>;q=0.8, ;q=0.75
Is there a way to prevent do_routing from adding that entry and/or remove it
after it has been added? OR is there a way to add a q-value to that
instance?
Thanks,
Ryan

Hi thrillerbe,
I think that if you only want to build the list of selected
destinations, you can just call use_next_gw and add the uri in RURI to a
destination string ( because use_next_gw sets the RURI to the destination-
http://www.opensips.org/html/docs/modules/devel/drouting.html#id251519
).
It would be something like this:
if (do_routing("1","2")) { if ($avp(s:dr_rules_attrs) == "2")
{
xlog("L_INFO","After 1, ds is $ru\n"); $var(x) = 2;
$var(ds) = $ru;
while (use_next_gw()) { $var(ds) = $var(ds)
+ "," + $ru;
xlog("L_INFO","After $var(x), ds is $var(ds)\n");
$var(x) = $var(x) + 1; } } xlog("L_INFO","Destination
set is $var(ds)\n"); }

Hi,
Another tricks:
1) you can read the pending destinations directly from AVPs, without
calling the "use_next_gw()" function. See:
http://www.opensips.org/html/docs/modules/1.6.x/drouting.html#id293166
2) as append_branch() does not accept variables as params, use the
"$branch" variable to write into:
http://www.opensips.org/Resources/DocsCoreVar16#toc15
like:
$branch = $var(x) ; #add a new SIP URI as extra branch
$(branch(q)[-1]) = 10 ; # set Q val for the last added brach

Re: [OpenSIPS-Users] drouting module with append_branch() and q-values
I was able to manipulate $ru as set by do_routing() to get the behavior I'm
looking for. It's not very clean, but it's functional.

Bogdan,
When I configure:
$(branch(uri)[0]) = $ru;
$(branch(q)[0]) = 100;
xlog("L_INFO","branch 0 = $(branch(uri)[0]) with q-value
$(branch(q)[0])\n");
I get this debug:
ERROR:core:pv_set_branch_fields: SCRIPT BUG - inexisting branch
assigment [0/0]
