Asterisk "no audio" issue Ubuntu 22.04 on C++/.NET experience

We run Asterisk on Ubuntu version 22.04 as latest, session we are having problems with is running 20.04 (slightly older) but I doubt that is causing problems with disconnects and possible
"no audio" issues
The issue is that agent does not answer or we receive silence from him
And the issue that did not hear but I told heard is that call some times end suddenly. But provider told these calls were completed with Bye

All extensions and mostly all configs are in ODBC. I will extract them to Excel for you.
Extensions also have ability to be changes on the fly, but for you it is mostly always on beginning of a new call when we build internal extension

Please if you can fix , we can work Long Term based on
Thanks
