<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">Also, to be fault tolerant, I noticed a call handed off to Stasis app will remain in the Stasis app, even if the ARI/WebSocket connection drops (power outage, etc). When establishing
the ARI/WebSocket connection, the first thing I am planning to do is GET a list of the channels. This returns all of the channels in the system and not just the channels that are in this Stasis apps control. I plan to go through the list and identify the
channels dialplan data. Look for app_name of Stasis and the app_data (comma-delimited).<o:p></o:p></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">If app_name = “Stasis” and app_data’s first section of the comma-delimited parse portion matches the Stasis app name this instance is used, I take control of this channel.<o:p></o:p></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">I am planning this additional check because I noticed the Stasis power outage scenario resulted in channels stuck in the Stasis app. If I don’t take control of these channels,
it’s possible to eventually have hundreds/thousands of channels. For SIP calls, the other end eventually hangs up. However, this isn’t the case with Local channels. Particularly when both ends are locally controlled by Stasis.<o:p></o:p></p>
