Re: [Serusers] BYE notifications not relayed in proxy call forwarding setup

28 May 2004

The problem is in the config file, you have to process Route header
fields in incoming messages using loose_route command, see the default
configuration file for more details.

 Hello.  I've been lurking for a while and I'm hoping that I have a pretty
 simple problem:

 My BYE notifications don't seem to be forwarded in a proxy'd call forwarding
 setup.
 The call connects fine, and I can talk back and forth ok, but if I hang one
 side the other remains connected.
 I tracked it down to the BYE notification not being relayed, but I'm not
 certain why.  Please help!

 Here is my ser.cfg:

 debug=3
 fork=no
 log_stderror=yes
 listen=69.20.20.192

 loadmodule "/home/zebra/sys/lib/ser/modules/sl.so"
 loadmodule "/home/zebra/sys/lib/ser/modules/tm.so"
 loadmodule "/home/zebra/sys/lib/ser/modules/rr.so"
 loadmodule "/home/zebra/sys/lib/ser/modules/exec.so"

 modparam("exec", "setvars", 1)

 route {
         if(method=="REGISTER") {
                 log("REGISTER received\n");
                 sl_send_reply("200","Ok");
         } else if(method=="BYE") {
                 log(1,"BYE received\n");
                 exec_msg("/home/zebra/bin/log_bye.php");
                 #sl_send_reply("200","Ok");
                 t_relay();
         } else {
                 # all other cases
                 log(1,"message received");
                 exec_dset("/home/zebra/bin/route_call.php -l");
                 record_route();
                 t_relay();
         }
 }

 ===========

 This is a very simple call forwarding arrangement.
 However, when using this SER does nothing with the BYE notifications!
 They just end up timing out.  I've attached the output from sip_scenario.pl.
 The proxy is 69.20.20.192.

 Any advice would be greatly appreciated!  This is causing me some headaches,
 and maybe I'm just not understanding what I'm doing with SER.
