[SR-Users] Kamailio problem route

Hello!

i am new in It, i speak spanish y very bad english, my problem is:

i want route to announcement when is busy or request timeout(486|408):

... ...

if(t_check_status("486|408")){ route(TEST); exit; }

route[TEST] { setflag(1); append_hf("P-App-Name: announcement\r\n"); rewritehostport("sip.inf.uct.cl:5080"); route("RELAY"); exit; }

route[RELAY] { if(is_method("ACK")) { exec_msg("/bin/echo " $$SIP_HF_FROM $$SIP_HF_TO $$SIP_RURI " >> /home/kaminfo/llamadas.log");

... ...

this just to prove that routing works.

call with linphone and gives an error that says "I'm terribly sorry, server error occurred (6/SL).

Are you missing something in code?

Please help, is my final

Thank you.
