<p>Hello,</p>
<p>isn't cnxcc capable of storing its information in a Redis server
and use it from there after restart?</p>

<div dir="ltr">Hi Everyone,
<div><br>
</div>
<div>My project involves keeping track of the allowable duration
for the caller to talk, and keeping track of the status of the
call with the back end database. Currently i have implemented
using the following modules (aside from the default modules in
the sample config script).</div>
<div>* http_async_client.so - to communicate with the backend DB</div>
<div>* dialog.so - mainly use to detect the 200 ok answer in
relation to invite, and the end of the call</div>
<div>* cnxcc.so - to release the call when the allowable talk
time is reached</div>
<div><br>
</div>
<div>The flow is as below:-</div>
<div><br>
</div>
<div>Invite -- > http to backend DB to ask for talk time</div>
<div> <-- DB returns value</div>
<div>200 ok (answer) ---> http backend DB to update that the
call has answered</div>
<div> <-- DB returns ok</div>
<div>dialog end or Cnxcc terminate --> http backend DB to
update that the call has hangup</div>
<div><br>
</div>
<div>My problem is that if there is a need to restart the
kamailio config there is no 'graceful' way to hangup all the
calls and inform the backend, or deny any new calls from
coming in. If kamailio is restarted then cnxcc would have
forgotten that there is a maximum talk time allowed to be
called or recover from the restart.</div>
<div><br>
</div>
<div>How to I make the system resilience to failures/restarts.</div>
<div><br>
</div>
<div>Appreciate any good suggestions. </div>
