stun_host property
Warning: deprecated, please use \a stun_srv field instead. To maintain backward compatibility, if \a stun_srv_cnt is zero then the value of this field will be copied to \a stun_srv field, if present.
Specify STUN server to be used, in "HOST:PORT" format. If port is
not specified, default port 3478 will be used.
Implementation
external pj_str_t stun_host;
