Hi Hi have read documentation but it seems dispatcher does not keep how many calls has been dispatched or currently are in any of dispatcher destinations I have take a look to code on: http://lists.sip-router.org/pipermail/sr-users/2012-July/073919.html But it seems to use calls limit per user, I would need to establish a limit per dispatcher destination i order to do not send more calls. Any idea where to look for? I have take a look to DMQ module, that maybe i could to use to spread information of how many calls to every destination but do not know how to extract calls from kamailio that have been dispatched to this destination using disptcher module. Best Regards Alberto

Thanks Olle for that tip I used *$ds* - reference to destination set after if(!ds_select_domain("1", "4")) { and be able to limit calls dispatched per destination Asterisk would control that, with that max calls, but i want a dinamic mecanism where to limit calls before dispatched to asterisk Will continue take a look. Dialog module is powerfull! Enjoy your holidays! Mine comes later... 2015-07-23 11:26 GMT+02:00 Olle E. Johansson <oej(a)edvina.net>et>:

The best way is to let the server you send the calls to decide when it has too many calls. It has all the states needed and should be able to block the call with an error response, preferrably in the 5xx range. Asterisk chan_sip will do this if you set maxcalls in asterisk.conf. I don’t remember the error code used and won’t check right now, as I’m on holiday :-) Having the same state in two different servers is looking for trouble. /O On 23 Jul 2015, at 11:16, Alberto Sagredo <alberto.sagredo(a)avanzada7.com> wrote: Sorry :) I found two scripts, the one on other mail worked fine per user limit is this one https://www.mail-archive.com/sr-users@lists.sip-router.org/msg07072.html Best Regards :) Any comment to improve it is welcome 2015-07-23 9:48 GMT+02:00 Alberto Sagredo <alberto.sagredo(a)avanzada7.com>om>:

Thanks Fred I will take a look to that and let you know Now using route[TOASTERISK] { if(!ds_select_domain("1", "4")) { sl_send_reply("500", "Service Unavailable"); xlog("L_INFO","[$fU@$si:$sp]{$rm} Sin destinos disponibles para $rd \n"); exit; } dlg_manage(); $var(SIZE) = 0; get_profile_size("callquota", "$ds", "$var(SIZE)"); if( $var(SIZE) >= MAX_NUMBER_OF_CALLS ){ xlog("L_INFO:Se ha alcanzado el máximo numero de llamadas para $ds : Limite $var(SIZE) llamadas\n"); sl_send_reply("503", "Simultaneous calls limit reached"); exit; } set_dlg_profile("callquota","$ds"); if (get_profile_size("callquota","$var(SIZE)")) { xlog("L_INFO: Hay $var(SIZE) llamadas encaminadas para $ds\n"); } route(RELAY); exit; } 2015-07-23 14:30 GMT+02:00 Fred Posner <fred(a)palner.com>om>:

Have you tried with algorithm 10 (call load distribution)? http://www.kamailio.org/docs/modules/4.3.x/modules/dispatcher.html You will need to set a few parameters such as duid, hash_size, etc. and then utilize the special attribute of maxload. Then, using ds_load_update and ds_load_unset dispatcher will update the load state for the node. Fred Posner fred(a)palner.com http://palner.com On 07/23/2015 03:48 AM, Alberto Sagredo wrote:
