[Serusers] PSTN => SER => PSTN - sr-users

21 Apr 2005


      I'm having an issue where my OUT PSTN is not getting a signal that a 
call has ended.
My setup is as follows:
IN                   OUT
PSTN  ==>  SER  ==>  PSTN
If I place a call and the person hangs up before the callee answers, the 
callee's phone just keeps ringing.
I see a CANCEL event on the SER box, but nothing on the OUT PSTN.
Here's a sample of my ser.cfg script:

log_stderror=yes
sip_warning=no
check_via=no

    if (!mf_process_maxfwd_header("10")) {

    		break;
    };
    if ( msg:len > max_len ) {
    		sl_send_reply("513", "Message too big");
    		break;
    };
if (method!="REGISTER") {
    	record_route();
    };
xlog("L_INFO", "#INFO# %rm\n");
if (loose_route()) { t_relay(); break; };
setflag(1);
if (method=="CANCEL"){
    	sl_send_reply("487", "Terminated");
    	break;
    };
if (method=="INVITE") {
    	if (uri=~"sip:[0-9]+@.*") {
    		xlog("L_INFO", "Original URI: %ru \n");
    		exec_dset("insert script here");
    		xlog("L_INFO", "Relay URI = %ru\n");
    		if (!t_relay()) {
    			sl_reply_error();
    			break;
    		};
};
    };
}
