Calls drop after 15 minutes with Twilio only - Follow Up

[davide.bonavita]

Hello,
as follow up of this closed thread: https://www.3cx.com/community/threads/calls-drop-after-15-minutes-with-twilio-only.84598/

Calls started to drop randomly today again. I had a long chat with Twilio's support and they indeed confirm they do not support Session expire: https://www.twilio.com/docs/sip-tru... not support Session,defaults of 1800 or 3600

They also checked their logs and it looks like that the BYE has been sent to Twilio from 3CX, which resulted in the call disconnect.
These are the relevant settings of the Twilio trunk:



I have the verbose logs for those calls, but I would like not to publish them here as I could leak some private data. More than happy to share them in DM

Thank you again for your help
