<h1><a name="AstriDevCon2011-Introduction"></a>1. Introduction</h1>
<p>AstriDevCon 2011 was held on Monday, October 24th. It was held on the day prior to AstriCon at the same location. A group of active development community members met and discussed a number of topics, including:</p>
<ul>
<li>Asterisk SCF Ideas</li>
<li>Asterisk 10 Ideas</li>
<li>Asterisk Test Framework Ideas</li>
<li>Asterisk Release Policy</li>
</ul>

<h1><a name="AstriDevCon2011-AsteriskSCFIdeas"></a>3. Asterisk SCF Ideas</h1>
<p>The Asterisk SCF discussion kicked off the morning. The topics that were covered included:</p>
<ul class="alternate" type="square">
<li>VMWare/Etc. Image</li>
<li>Channel driver</li>
<li>ICE management tools.</li>
<li>Queues</li>
<li>Security, security, security</li>
<li>Do we build the security functionality into the SCF code, or do we simply define best practices for securing an SCF system?</li>
</ul>
<h1><a name="AstriDevCon2011-Asterisk10Ideas"></a>4. Asterisk 10 Ideas</h1>
<p>We spent probably half of the day discussing Asterisk 10. We came up with a list of development projects we'd like to get done and then prioritized them.</p>
<h2><a name="AstriDevCon2011-%28P0%29"></a>4.1. (P0)</h2>
<p>P0 are committed projects that are going to get done.</p>
<ul>
<li><del><a href="/wiki/display/AST/T.38+Gateway" title="T.38 Gateway">T.38 Gateway</a></del> (Digium)</li>

<ul>
<li><del>(work is already being done on this front)</del></li>
</ul>
</li>
<li>SIP path support (Olle)
<ul>
<li>(first generation of code exists, needs more work, simple patch, going to get it done, needs an extra field in astdb; helps when there are 2 or more load balancing proxies in front of asterisk, when you'd like the call to be able to get back to Asterisk; see <a href="https://reviewboard.asterisk.org/r/991/" class="external-link" rel="nofollow">https://reviewboard.asterisk.org/r/991/</a>)</li>
<li><a href="https://issues.asterisk.org/view.php?id=18223" class="external-link" rel="nofollow">https://issues.asterisk.org/view.php?id=18223</a></li>
</ul>
</li>
<li>Group variables (Kobaz)
<ul>
<li>(on review board, in progress)</li>
</ul>
</li>
<li>Pre-Dial (Kobaz)
<ul>
<li>(practically done, or something)</li>
</ul>
</li>
<li>Distributed extension state using SIP (Olle)
<ul>
<li>(resources in place, doing it, 1.4 done before Christmas, project pinana)</li>
</ul>
</li>
<li>Manager event docs (Paul Belanger)</li>
<li>Cross-platform documentation (Ben Klang)
<ul>
<li>(caveats for using Asterisk on operating system xyz; pull a PDF of the Wiki documentation into the source, don't forget to include basic installation information, and do it all in .txt - Ben)</li>
</ul>
</li>
<li>Fix libs to optionally init OpenSSL (Digium)
<ul>
<li>(or use existing tools; sort of a bug)</li>
</ul>
</li>
<li>Make ast_channel an opaque type (Digium)</li>
</ul>
<h2><a name="AstriDevCon2011-%28P1%29"></a>4.2. (P1)</h2>
<p>P1 is the highest priority.</p>
<ul>
<li><del><a href="/wiki/display/AST/Media+Overhaul" title="Media Overhaul">Codecs (SILK, OPUS), Media Negotiation</a></del> (Digium)</li>
<li>RTCP (Olle)
<ul>
<li>Pinefrog; Work to be done - Ported to trunk, added to CEL</li>
</ul>
</li>
<li><del>Conferencing that supports a new magic media</del> (Digium)
<ul>
<li><del>higher sampling rates</del></li>
</ul>
</li>
</ul>
<h2><a name="AstriDevCon2011-%28P2%29"></a>4.3. (P2)</h2>
<ul class="alternate" type="square">
<li>Async DNS (TCP DNS and use a good resolver)</li>
<li>Named ACLs (deluxepine)</li>
<li><a href="/wiki/display/AST/SIP+Security+Events" title="SIP Security Events">SIP Security Events</a></li>

<li>IPv6 for the restivus (IAX, Jabber/XMPP/Gtalk, Manager, etc.)</li>
<li><del>ConfBridge feature complete with MeetMe</del></li>
<li>Support sound file containers (matroska)</li>
</ul>
<h2><a name="AstriDevCon2011-%28P3%29"></a>4.4. (P3)</h2>
<ul>
<li>Who hung up? (there's a branch, shouldn't take too much time - Olle)</li>
<li>Unique identifier for filtering log data to a call
<ul>
<li>(finishing what was already begun w/ Clod's project, CLI filtering; should take a look at what Stephan from Unlimitel.ca's created)</li>
</ul>
</li>
</ul>
<h2><a name="AstriDevCon2011-%28P4%2CSimon%27sfeatures%29"></a>4.5. (P4, Simon's features)</h2>
<ul>
<li>Multiple SIP Sockets
<ul>
<li>(Listen on multiple ports or on multiple interfaces, but not all; also set binding for RTP)...alternate idea / solution would be to make Asterisk capable of loading multiple SIP profiles, it might be easier</li>
</ul>
</li>
<li>Multiple DNS results
<ul>
<li>(need to be able to traverse a list of DNS results, rather than just getting back one result)</li>
</ul>
</li>
<li>ICE-lite
<ul>
<li>(no code, responding correctly to ICE connectivity checks (STUN multiplexed on the RTP port) and understanding the SDP); it makes NAT traversal work for clients that do ICE; also addressed lightweight NAT refresh)</li>
</ul>
</li>
</ul>
<h2><a name="AstriDevCon2011-%28P5%29"></a>4.6. (P5)</h2>
<ul>
<li><del>AstDB replacement</del> SQLite
<ul>
<li>(realtime, there's code, nearly ready)</li>
</ul>
</li>
<li>SIP identity
<ul>
<li>(on reviewboard; needs to be forward ported; important for organizations w/ federated identities; a requirement for DTLS SRTP; not widely deployed)</li>
</ul>
</li>
<li>RTMP client channel driver</li>
</ul>
<h2><a name="AstriDevCon2011-%28P6%29"></a>4.7. (P6)</h2>
<ul>
<li>Structured identifiers for errors
<ul>
<li>(tag an error message with a unique string, specific to the error message and where it came from; should be alphanumeric to keep them short)</li>
</ul>
</li>
<li>AMI SetVar, Context limits
<ul>
<li>(there's code already...Olle has it)</li>
</ul>
</li>
<li>AMI filters on demand</li>
<li>DTLS SRTP
<ul>
<li>(not likely to be widely deployed in the next 12 months)</li>
</ul>
</li>
</ul>
<h2><a name="AstriDevCon2011-%28P7%2Cnotkobaz%29"></a>4.8. (P7, not kobaz)</h2>
<ul>
<li>Asterisk register for XMPP account (Leif)</li>
<li>Write a Specification for AMI (not kobaz)</li>
<li>Multiple TLS server certs
<ul>
<li>(1 socket, requires support by OpenSSL; simpler to implement than multiple SIP profiles; don't know if any clients use it yet; needs more research)</li>
</ul>
</li>
</ul>
<h2><a name="AstriDevCon2011-%28P8%2Cnicetohave%29"></a>4.9. (P8, nice to have)</h2>

<ul>
<li>(Tabled for later discussion)</li>
</ul>
</li>

<ul>
<li>(we may already have it, needs research to see if the realtime driver does what's desired - Leif)</li>
</ul>
</li>
<li>Device state normalization</li>

<h1><a name="AstriDevCon2011-TestingFrameworkIdeas"></a>5. Testing Framework Ideas</h1>

<h1><a name="AstriDevCon2011-ReleasePolicyDiscussion"></a>6. Release Policy Discussion</h1>
<p>We discussed Asterisk release policy. Specifically, we were considering the current policy that excludes features from a release branch. After a bit of discussion, it was decided that no changes to policy would be made. We did agree that a new self contained module that was not compiled by default would be fine, but that it would be rare that it would provide benefit, since most projects are modifications of existing code.</p>
