Re: [SR-Users] Parallel call forward

Setting to $null means deleting the avp -- so remove the [0] from that assignment.

What function are you using to send out the request? Can you sent the cfg execution trace (see debugger module)?

Also, have you tried to troubleshoot using $branch(...) variables?

Cheers, Daniel

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.

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
