Solved Calls drop after 15 minutes with Twilio only

[davide.bonavita]

Hello all,
I've read some previous posts but I couldn't find anything useful for my case. With Twilio and Twilio only some calls (not every call!!) drop after 15 minutes. I've configured the trunk using the default Twilio template and as per my signature we have two 3CX instances hosted on AWS Lightsail. The firewall checker is all green. The agents all use the Chrome extension or the webclient, no hardware phones or mobile apps. From the Twilio logs it seems the call is disconnected from the 3CX side. Is there anything I can double check in the trunk configuration?
Thank you for your help, sadly we can't use Twilio as long as we have this issue

I've already done this and tomorrow I'll know if this fixes it, thank you

Hello, sadly it's still happening. I'm not able to reproduce the issue whilst the network traffic capture is active as it doesn't happen for every call, it happens randomly.

That is very strange since Twilio does not use session timers and calls dropping after 15 minutes is usually a sign that a session timer issue is at play here.
Set the logging lever of the PBX to verbose and once the issue occurs check the activity log for why the call dropped. You can filter via call and only get the results for the call the failed. Also I would recommend updating to V18 and see if you are still facing the issue.

Hi Yannish, it seems it solved by itself after 1 day. Thank you for your help
