# example script showing both types of forking;
# incoming message is forked in parallel to
# 'nobody' and 'parallel', if no positive reply
# appears with final_response timer, nonsense
# is retried (serial forking); than, destination
# 'foo' is given last chance
# ------------------ module loading ----------------------------------
loadmodule "modules/sl/sl.so"
loadmodule "modules/tm/tm.so"
# ----------------- setting module-specific parameters ---------------
# -- tm params --
# set time for which ser will be waiting for a final response;
# fr_inv_timer sets value for INVITE transactions, fr_timer
# for all others
modparam("tm", "fr_inv_timer", 15 )
modparam("tm", "fr_timer", 10 )
# ------------------------- request routing logic -------------------
# main routing logic
route{
# for testing purposes, simply okay all REGISTERs
if (method=="REGISTER") {
log("REGISTER");
sl_send_reply("200", "ok");
return;
};
# try these two destinations first in parallel; the second
# destination is targeted to sink port -- that will make ser
# wait until timer hits
seturi("sip:nobody@siphub.net");
append_branch("sip:parallel@siphub.net:9");
# if we do not get a positive reply, continue at reply_route[1]
