I am trying to send a SIP SIMPLE message from handset 101 registered to switch A to handset 202 registered on switch C.  Switch B is in the middle and is a gateway for switch A, so it looks something like this:<div><br></div>

<div>101 -----  FS A -----gw------- FS B -----------gw------- FS C --------- 202</div><div><br></div><div>I was able to get something working with the chatplan by setting the &quot;to&quot; parameter to point to FS B and then on FS B setting the to parameter to point to FS C.  I don&#39;t know if this is even the best way to do it, but that&#39;s how I got it to work.  What I would like, however, is to use TLS on all links.  I currently have TLS on all links for phone calls, but I guess the chatplan doesn&#39;t use the same logic as the dialplan so by default, it is using UDP between the switches.  I have been looking through the source trying to find out what I can set to enable TLS for SIMPLE between switches but I have been unsuccessful thus far.  Any help would be greatly appreciated.</div>
