Re: Re: Re: Re: [Serusers] a question about "cancel" in forwardingscenario

Dear Greger V. Teigre, Thanks for your quick reply. I have read the sergettingstarted05.pdf (Based upon SER version 0.9.3) and tested the onr.cfg in ser-0.9.3.GettingStarted.1.3.tar.gz/ser-0.9.3/examples many times. SER sent out "408" to caller immediately after received "486" from ua3. I don't know how does ser's failure route deal with this kind of "cancel" when the invite has been forwarded. Any ideas will help me a lot. Thanks! Here is the onr.cfg: # ------------------ module loading ---------------------------------- loadmodule "/usr/local/lib/ser/modules/sl.so" loadmodule "/usr/local/lib/ser/modules/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"); break; }; # 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:200@218.97.252.35:5060"); #append_branch("sip:300@218.97.252.36:5060"); # if we do not get a positive reply, continue at reply_route[1] t_on_failure("1"); # forward the request to all destinations in destination set now t_relay(); } failure_route[1] { #when caller cancel, terminate the call if (t_check_status("487")) { t_reply("487", "Request Terminated"); break; }; # forwarding failed -- try again at another destination append_branch("sip:300@218.97.252.44:5060"); log(1,"first redirection\n"); # if this alternative destination fails too, proceed to reply_route[2] #t_on_failure("2"); t_relay(); } Thanks in advance. Have a good day!
