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
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

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.

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?

After playing with the $brach(...) ... I found what was happening and fixed it. A missing call to setup the $du of the branches ... now working as expected.
