Offcourse, fiddle with t_set_fr on a per call basis or the fr_inv_timer/fr_timer: http://www.kamailio.org/docs/modules/5.2.x/modules/tm.html#tm.f.t_set_fr SERIALRELAY is used in stead of the normal RELAY route, it loads available endpoints with t_load_contacts: http://www.kamailio.org/docs/modules/5.2.x/modules/tm.html#tm.f.t_load_contacts and fetches the first one with t_next_contacts. In the failure route keep calling t_next_contacts till there are no more. route[SERIALRELAY] { if (is_method("INVITE|SUBSCRIBE")) { t_on_branch("MANAGE_BRANCH"); t_on_reply("MANAGE_REPLY"); } if (is_method("INVITE")) { t_load_contacts(); t_next_contacts(); t_on_failure("SERIAL_FAILURE"); } if (!t_relay()) { sl_reply_error(); } break; } failure_route[SERIAL_FAILURE] { if (!t_next_contacts()) { send_reply("408","Timeout or nobody available"); exit; } t_on_branch("MANAGE_BRANCH"); t_on_reply("MANAGE_REPLY"); t_on_failure("SERIAL_FAILURE"); t_relay(); } _______________________________________________ Kamailio (SER) - Users Mailing List [email protected] https://lists.kamailio.org/cgi-bin/mailman/listinfo/sr-users
