Hi List
I'm trying to inspect the content of the $xavp(tm_contacts) to figure
out how t_load_contacts exactly behaves when called multiple times.
$var(k) = 0;
while ($xavp(tm_contacts[$var(k)]) != $null) {
$var(out) = "nothing";
xavp_params_implode("tm_contacts[$var(k)]",
"$var(out)");
xlog("L_INFO", "$cfg(route): tm_contacts idx:
$var(k) => $var(out)\n");
$var(k) = $var(k) + 1;
}
My stack contains multiple entries.
Unfortunately I struggle to access the lower entries.
xavp_params_implode("tm_contacts[$var(k)]", "$var(out)");
does nothing when $var(k) > 0
What is the best way to dump a complete xavp stack?
I suspect t_load_contacts does flush the complete stack. Is there a way
to stack an xavp on top of another one?
Something like:
xavp_rm("contact_stack"); # Initialize Stack
lookup("location", "sip:alice@example.com");
t_load_contacts(0);
$xavp(contact_stack) = $xavp(tm_contacts);
lookup("location", "sip:bob@example.com");
t_load_contacts(0);
$xavp(contact_stack) = $xavp(tm_contacts); # contact_stack now contains alice + bob
lookup("location", "sip:carlie@example.com");
t_load_contacts(0);
# $xavp(tm_contacts) now contains only charlie.
$xavp(tm_contacts) = $xavp(contact_stack);
# $xavp(tm_contacts) now contains only alice, bob + charlie.
t_next_contacts(); # Push contacts to destination list creating branches.
t_relay(); # Invite all contacts
Mit freundlichen Grüssen

Hi,
You can use $cnt(pv) to count the number of xvps…
https://www.kamailio.org/wikidocs/cookbooks/5.8.x/pseudovariables/#cntpv-co…
And then do a while ($xavp(tm_contacts[$var(k)]) < the count.
Regards,
Fred Posner

I guess this is allmost the same but my issue is with the last line
when I try to implode a specific element of the stack into $var(out)
If it's not element 0 I get 'nothing' and I am sure there is content.

Hi,
$cnt is useful -- didn't know about it!
But I wonder, can you not just combine these operations into one loop?
while($xavp(tm_contacts[$var(k)]) ne $null)
or
while(defined $xavp(tm_contacts[$var(k)]))

Hi
But I wonder, can you not just combine these
operations into one loop?
My issue is not the loop, that works fine.
My issue is accessing / dumping the content of the xavp element 'k' in
this loop.
And then the next challenge is, how to concatenate two xavp stacks.
All with the goal to be able to parallel branch a call to multiple
destinations gathered from locations contact of multiple AoR (in case I
am trying to overcomplicate this, please tell me the obvious solution
I'm missing :-) )

Hi Ben

https://kamailio.org/docs/modules/5.6.x/modules/pv.html#pv.f.xavp_params_im…
That is exactly what I try to do:
$var(k) = 0;
while ($xavp(tm_contacts[$var(k)]) != $null) {
$var(out) = "nothing";
xavp_params_implode("tm_contacts[$var(k)]",
"$var(out)");
xlog("L_INFO", "$cfg(route): tm_contacts idx:
$var(k) => $var(out)\n");
$var(k) = $var(k) + 1;
}
I know there are 4 elements on the stack as the while looks runs for k
from 0 to 3.
But $var(out) only contains data when k is 0 so I am unable to dump
the other elements on the stack.

You might be overcomplicating this, as parallel forking is out-of-the-box behaviour for
lookup(), provided that `append_branches` is set to 1:
https://kamailio.org/docs/modules/5.8.x/modules/registrar.html#idm175
It's the serial forking across contacts that takes extra work. With the parallel
forking, you don't need to mess with t_load_contacts() / t_next_contacts() at all.

This is, why I first try to get parallel forking to work, but somehow I
don't.
Again what I want to do in this, I assume, simple and common scenario:
I have AoR alice registered with 4 contacts all with q=0.5
I have AoR bob registered with 1 contact with q=0.5
I try to get those total of 5 contacts in my destination set and
parallel fork a call to those 5 contacts.
I got this working the 'very hard' way by making use of
reg_fetch_contacts and append_branch and setting 'most' branch values from the
$ulc()
variables, but this need manual tweaking each time I add some
functionality like NAT or PATH support.
=> There must be an easier way, right?
What am I missing with the lookup() function to make this work
'out-of-the-box'?

Hello,
just using lookup() should do the job. It should create additional branches at the
execution of t_relay(). If its not working maybe the module is configured in a
non-standard way.
Cheers,
Henning

maybe printing all xavps and analyzing the output is a simpler way to try:
