<p><b>Digium Developer Conference Bridge:</b></p>
<p>Bridge: 35039</p>
<p>PIN: 35806</p>
<p><b>Proposed Agenda:</b></p>
<p>Welcome & Announcements:</p>
<ul>
<li>Introduction of Digium participants</li>
</ul>
<p>Old Business: </p>
<ul>
<li>None</li>
</ul>
<p>New Business:</p>
<ul>
<li>Discussion of current SCF development status</li>
<li>Discussion of progress and anticipated dates for developer APIs</li>
<li>Discussion of results from SIPit 28:</li>
</ul>
<p>Specific areas tested:</p>
<p>Session setup/teardown<br/>
UDP/TCP/TLS calls on IPv4 and IPv6<br/>
SIP dynamic configuration (add/remove endpoints)<br/>
RTP state replication<br/>
Removing components in mid-operation (routing, bridging, media)<br/>
Attempting calls with components not running (routing, bridging, media)<br/>
SIP PRACK<br/>
SIP attended transfer (see bug list)<br/>
Unhandled SIP methods</p>
<p>Issues encountered:</p>
<p>April 11th<br/>
* Configurator should output help message if nothing is specified on command line -> Tweaked message<br/>
* Pushed transports do not work -> Fixed<br/>
* Pushed endpoints do not update routing -> Fixed<br/>
* pjsip_tls_transport_start being used while not present -> Fixed<br/>
* Crash in routing service when updating destionation ids -> Fixed<br/>
* Some endpoint config items not being processed -> Fixed</p>
<p>April 12th<br/>
* Dialing something that does not exist causes deadlock -> Fixed, configuration issue (thread pool size was not large enough, need to document)<br/>
* Trying to call an endpoint with no configured target host and port causes assertion -> Fixed<br/>
* Trying to end a call for an endpoint that is not answering fails -> Fixed<br/>
* TLS in pjsip and linking against OpenSSL is a slight mess, we need to link against it<br/>
* We do not use sips URIs for TLS, this causes the pjsip transport selector to select wrong transport<br/>
* Attempting to contact an IPv6 UA without the needed transport crashes SIP component -> Fixed</p>
<p>April 13th<br/>
* PRACK support incomplete -> Fixed<br/>
* Found issue with AMI migration of transfer related calls to routing, could cause a crash (405)<br/>
* We silently drop SIP packets for methods we do not support/have implemented -> Fixed<br/>
* Attempting to place a call when RTP component goes down causes failure -> Fixed<br/>
* Attempting to hangup a call when RTP component goes down causes failure -> Fixed<br/>
* RTP state replication fails to replicate state items -> Fixed</p>
<p>April 14th</p>
<p>* Found potential race condition in RTP state replication -> Fixed<br/>
* Regression found in fix for silently dropping SIP packets -> Fixed<br/>
* Added support for SIP session timers</p>
<p>April 15th</p>
<p>Areas of improvement:</p>
<p>* Configuration mechanism should have some manner of notifying that specific configuration could not be applied<br/>
* Configuration mechanism should have some manner of notifying that a requirement for configuration was not met<br/>
* SIP configurator does not have a log message when invalid section is read<br/>
* Create separate module for replying to SIP packets that contain methods we do not support/have implemented<br/>
* Configuration mechanism should have some manner of notifying that something non-configuration related went wrong<br/>
* Make waits in RTP unit test timed in case state replicator fails to push out items<br/>
* Remove requirement for predefined global adapter port numbers for replicated components<br/>
* Replicate configuration as well as state</p>
