[SR-Users] Calling t_on_reply in branch_route doesn't work in Kamailio 3.1 - did work in Kamailio 1.5

Hi, I'm currently migrating a Kamailio 1.5 installation to Kamailio 3.1.3, and I got all config changes merged, except this one: branch_route[1] { if ((isbflagset(4)) && (!isflagset(7))) { fix_nated_sdp("1"); if (has_body()) { force_rtp_proxy("R"); } else { setflag(5); } t_on_reply("2"); } } In Kamailio 1.5 this worked without problems. In Kamailio 3.1 I get the following error (line 1627 is the line with t_on_reply on it): hostname:~# /usr/sbin/kamailio -c -f /etc/kamailio/proxy/kamailio.cfg loading modules under /urs/lib/kamailio/modules/:/usr/lib/kamailio/modules_k:/usr/lib/kamailio/modules_s/ 0(13670) : <core> [cfg.y:3412]: parse error in config file /etc/kamailio/proxy/kamailio.cfg, line 1627, column 17: Command cannot be used in the block ERROR: bad config file (1 errors) hostname:~# In the Kamailio 1.5 documentation it was stated for every t_on_* function, where it could be called. For t_on_reply it said: This function can be used from REQUEST_ROUTE, BRANCH_ROUTE, ONREPLY_ROUTE and FAILURE_ROUTE. In the Kamailio 3.1 documentation those lines are missing. But I don't really see a reason, why t_on_reply shouldn't be called from branch route. We need it for every branch to possibly have different onreply_routes. Am I missing something? Thanks in advance for any hints. Best regards, Sebastian
