In 1.6, this parameter has profound effects but is not documented or
represented in any sample configs:
[root@csrpsemsus1 sems]# fgrep -HR default_bl_ttl . | grep -v Binary
./core/SipCtrlInterface.cpp: if (cfg.hasParameter("default_bl_ttl")) {
./core/SipCtrlInterface.cpp: trans_layer::default_bl_ttl =
./core/SipCtrlInterface.cpp: cfg.getParameterInt("default_bl_ttl",
./core/SipCtrlInterface.cpp:
trans_layer::default_bl_ttl);
./core/SipCtrlInterface.cpp: DBG("default_bl_ttl =
%u\n",trans_layer::default_bl_ttl);
./core/sip/trans_layer.cpp:unsigned int _trans_layer::default_bl_ttl =
DEFAULT_BL_TTL;
./core/sip/trans_layer.cpp: if(default_bl_ttl) {
./core/sip/trans_layer.cpp:
default_bl_ttl,"503");
./core/sip/trans_layer.cpp:
default_bl_ttl,"503");
./core/sip/trans_layer.cpp: if(default_bl_ttl) {
./core/sip/trans_layer.cpp:
default_bl_ttl,"503");
./core/sip/trans_layer.cpp: if(default_bl_ttl) {
./core/sip/trans_layer.cpp:
default_bl_ttl,
./core/sip/trans_layer.cpp: if(default_bl_ttl) {
./core/sip/trans_layer.cpp:
default_bl_ttl,"503");
./core/sip/trans_layer.h: static unsigned int default_bl_ttl;
I think this is a big problem. We had to track it down in the source to
figure out why 90% of our calls were being rejected out of hand with
'500 No destination available'.
