I&#39;m in the process of testing a TLS/SRTP install.  My experience is improving with each new challenge, but this one is a great test of my 2 month experience with Asterisk.<br><br>When I dial 6003 from 6001, it takes 35 seconds until I get the error message that 6003 is circuit-busy.<br>
<br>Any help would greatly be appreciated.  Below is the error message and the extensions and sip.conf files.<br><br><br><br>*CLI&gt;   == Using SIP RTP CoS mark 5<br>    -- Executing [6003@myphones:1] Set(&quot;SIP/6001-0000000c&quot;, &quot;_SIPSRTP_CRYPTO=enable&quot;) in new stack<br>
