[Serusers] Nathelper config and t_relay_to

Hello, i am new to ser and i am currently testing the ser 0.8.13-dev-23-merged with the supplied nathelper config and client authentication via mysql. So far everything looks good. Now i started to add some PSTN routing to the script. I replaced --- if (!t_relay()) { sl_reply_error(); }; --- with --- # Route to PSTN Gateways(s) if (uri=~"^sip:9[0-9]*@my.domain.net") { ## This assumes that the caller is log("Forwarding to PSTN\n"); ## registered in our realm t_relay_to( "my.psnt.gw.ip-addr", "5060" ); break; } else { if (!t_relay()) { sl_reply_error(); }; }; --- in the route[1] function of the nathelper config. Allthough the tm.so module is installed (ser cant work without it, right) i get the following error while starting ser: --- Jan 9 08:36:17 gk ser: parse error (225,41-42): unknown command, missing loadmodule? --- Line 225 is --- t_relay_to( "my.psnt.gw.ip-addr", "5060" ); --- and according to all examples and modules/tm/README this is the correct syntax. Any ideas? best regards, Arnd
