I decided using your recommendation with AVP. Until now I kept some distance to this mechanism (AVP in general). But because of having no alternative (std. $var can not work, avoidance of self compilation for a customer project a.s.o.) I have limited the number of hits - it is now working fine. Without any dirty hack ;-) Thanks and best regards, Klaus P.S. the abstract solution route[YZ] { if (!ds_select_dst("1", "4")) { .. } $avp(i:9)=1; t_on_failure("xy"); t_on_reply("yz"); t_set_fr(3000, 750); t_relay(); exit; } failure_route[xy] { [...] if ($avp(i:9) < 10){ $avp(i:9) = $avp(i:9) + 1; #!ifdef WITH_XLOGDEBUG xlog("L_INFO", " <FAILXY> the new value of branch counter is: $avp(i:9) \n"); #!endif } else { #!ifdef WITH_XLOGINFO xlog("L_INFO", " <FAILXY> distr. was interrupted due to too many faulty GWYs \n"); #!endif t_reply("480", "Temporarily Unavailable"); exit; } if (!ds_next_dst()) { .. } [...] } _______________________________________________ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users@lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users
