[sr-dev] [kamailio/kamailio] Module RTPPROXY param Timeout_Socket not Working (#1597)

Kamailio didn't start listening on IP mentioned in Module RTPPROXY parameter [Timeout_Socket](https://kamailio.org/docs/modules/5.1.x/modules/rtpproxy.html#rtpproxy.p.tim...).

Below is my configuration file. ``` loadmodule "rtpproxy.so" modparam("rtpproxy", "rtpproxy_sock", "udp:127.0.0.1:7722") modparam("rtpproxy", "rtpproxy_tout", 1) modparam("rtpproxy", "rtpproxy_retr", 2) modparam("rtpproxy", "timeout_socket", "tcp:127.0.0.1:7725") ``` when I type a commmand on linux

```$ netstat -nlp```

it only shows SIP listening ports. Kamailio should start listening on ```tcp:1270.0.01:7725```
