<p>Hello</p>
<p><br>
</p>
<p>we have a Freeswitch installation for a multi tenant environment.
We have extensively tested our Freeswitch for all call scenarios
and all worked fine. This is the good news.<br>
</p>
<p>However, under higher load (>250 Channels and >6000
Subscriptions), presence does not seem to work reliably. I've
found some ealier posts on this issue, which seem to lead to the
following 2 solutions</p>
<ul>
<li>use PostgreSQL (we use Mariadb via ODBC, also tested
mod_mariadb, which made things worse)</li>
<li>Move presence handling to Kamailio <br>
</li>
</ul>
<p>As your environment is based on MySQL, we do not want to move to
PostgreSQL without knowing, whether this will improve the
situation.</p>
<p>So far we are catching events via ESL or even grepping the
network and correct the status of presence informatons sent to the
phone. However we discover, that even if we send corrected
PRESENCE_IN via event socket, our Freeswitch keeps on sending the
wrong BLF information afterwards to the phone. Means BLFs are
blinking or in state red event if the watched phone is not in a
call. So at present we are grepping all presence informations on
the network, crosscheck this with the channels table and resend
the corrected BLF status via event_socket if needed. But still
this is not sufficiant.<br>
</p>
<p>So I am now asking the community: What is your approach to
overcome this? <br>
</p>
<ul>
<li>Do newer Freeswitch versions perform better for this
case?(Ours is "FreeSWITCH Version
1.10.5-release+git~20200818T185121Z")</li>
<li>which work have you done to overcome this?</li>
<li>does anybody have an idea how to query all internal presence
status from Freewitch or maybe how to correct it?<br>
</li>
</ul>
<p>Thank you in advance. Any help is appreciated.<br>
</p>
<p>Peter</p>
