hello,
that was a problem when i did cut and paste from the ser.cfg, it should be
as below,
} else if (uri=~"^sip:500@") {
log(1, "Accessing Voicemail\n");
setflag(1);
rewriteport("5065");
t_relay_to_udp("192.168.1.201","5065");
break;
} else if (uri=~"^sip:3[0-9]*@192.168.1.201") {
# call hunt numbers beginning with 3
log(1, "beginning with 3\n");
seturi("sip:8001211 at 192.168.1.201");
append_hf("P-hint: call hunt\r\n");
xlog("L_ERR", "time [%Tf] method <%rm> r-uri
<%ru> <%tu>\n");
t_on_failure("1");
t_relay();
}
