TLS has nothing to do with the SRTP/ZRTP. It only secures the signalling, media is secured separately. It&#39;s possible to secure either one without the other. You should *always* use TLS with SRTP though since the keys are sent in the SIP layer, but that&#39;s as far as it goes.<div>

As far as my understanding, it means that FS enable SRTP only when<br>
/sip_secure_media=true/ in the dialplan?<br>
<br>
OR<br>
<br>
Setting /transport=tls/ in the dialstring?<br>
<br>
If i left both to false, and ZRTP to enabled, it should support ZRTP only?<br>
right?<br>
