Some mod_dialogflow sessions are not freed about drachtio-freeswitch-modules HOT 7 CLOSED

would it be possible to send me a full freeswitch log -- with sip tracing on, and at DEBUG level like you have above -- which contains at least one example each of a "good" and a "bad" call? I would like to be able to follow the full call trace. Its ok if there are a lot of other calls in there as well, as long as you can give me the session id for the good and bad calls. Feel free to send to me at [email protected] rather than posting publicly if you like

Thanks, Dave. Sure, I will send logs to email. Currently the system has few calls, but I expect next peak in 8 hours or so.

Btw have you ever seen something like this under load?:

Is any recommendation for setup at 2021?
I.e. debian 9, no docker, [email protected],
[email protected], [email protected] and drachtio-dialogflow-phone-gateway@master
without docker?

I've not seen the error about SYN flood before. I would make sure outside traffic cant reach freeswitch port 8021.

I much prefer to run on VMs rather than inside docker, myself. I build freeswitch 1.10.5 on debian 10 for my own purposes:

Thanks, Dave, I will try convert suggested playbook.
Btw I've send logs to your mail, since they contain sensitive data.

It was related to https://github.com/drachtio/drachtio-dialogflow-phone-gateway, I slightly rewrited it to close sessions in different hangup cases, and now problem is gone

would you care to make a PR for your changes to that app?
