I did not use the index to erase pull from the stack I directly set it to null

$(avp(s:cf_destinations)[0]) = $null;


If I do this:

$var(new_ru) = $(avp(s:cf_destinations)[0]);
...
append_branch($var(new_ru));
...

I got the same result ... just the LAST $ru I set is the one thats called.

Asunto: Re: [SR-Users] Parallel call forward
Hello,

you should not use index when setting an avp to null -- remove the [0].

Then you can print details of branches voa $branch(...) variable to see what are the results of your operations.

A branch can be added also by providing the uri as parameter for append_branch() -- see the documentation of the function in the corex module.

Cheers,
Daniel

Hi all,

I'm getting crazy trying to setup a kamailio to do a parallel call forward to multiple destinations based on a query to the DB.

I do the db query and get the RURI's of the destinations I could forward the call to in parallel, then when I get the resulset I do:

[...]

$var(cf_idx) = 0;
while(is_avp_set("$(avp(s:cf_destinations)[0])"))
{
$ru = $(avp(s:cf_destinations)[0]);             # Set the new RURI to call to
$(avp(s:cf_destinations)[0]) = $null;           # Setting it to $null pull the value from the stack
$(avp(s:callee_fr_inv_timer)[*]) = $(avp(s:cf_timeouts)[0]) * 1000;
t_set_fr("$avp(s:callee_fr_inv_timer)");
$(avp(s:cf_timeouts)[0]) = $null;
route(ROUTE_ACC_CF);                          # Do the ACC
$(avp(s:acc_state)[*]) = "cfna";
$(avp(s:hih_cause)[*]) = "404";
$var(cf_idx) = $var(cf_idx) + 1;
append_branch();
}
route(ROUTE_EXECUTE_CF_LOOP);     # Some final task and then t_relay

[...]

But only the last RURI get called

How do I do to accomplish this? ... I need to change the $ru of each new branch, so when request get loop-back to the proxy, it do again all the lookup logic.


Best regards
