Fri Jun 26 17:50:11 CEST 2020
### Description
I found that kamailio ignores ICMP messages from remote hosts
### Expected behavior
Immediately failover after ICMP message.
#### Actual observed behavior
kamailio ignores ICMP messages
#### How to reproduce
Create kamailio config
```
loadmodule "pv.so"
loadmodule "tm.so"
listen = udp:eth0
request_route {
$du = "sip:127.0.0.1";
t_relay();
}
```
Start kamailio using the command
```
kamailio -DD -E -ddd
```
Make a call.
