<div>Hello,</div>
<div> </div>
<div>I have a requirement where the TLS connection initiated by kamailio shall stay to reuse by the sip server. The sip server is expecting PING on the TLS connection as as per the RFC 5626.</div>
<div> </div>
<div>Is there any plan to implement ping "CRLF CRLF" send by kamailio as per the RFC 5626.</div>
<div> </div>
<div>Thanks</div>
<div>Jijo<br></div>

crlfcrlf sent by the client, but can't be configured to send the<br>crlfcrlf. Is this right?<br><br>2. On my client, if I use setsockopt to set the corresponding values:<br><br> SO_KEEPALIVE<br> TCP_KEEPCNT<br> TCP_KEEPIDLE<br>
TCP_KEEPINTVL<br><br>would it make the client send crlfcrlf?<br><br>The reason I'm confused is, with these settings, if Kamailio can only<br>respond to crlfcrlf, but not send, then would the client only respond<br>too, as in 1. and 2., they seem to configure the same set of parameters?<br>
Please help me clarify this.
