While the RFCs contain a lot of information, it is mostly oriented at implementation of the ICE protocol and is not necessary for using Asterisk's ICE support. At a user level ICE uses SDP offer/answer, so the general concepts are fairly easy to follow for those familiar with SIP. Also, the details of visually interpreting candidate lists are fairly straightforward and are as easily digestible as media format SDP after a small amount of practice.</p>
