Thank you for the crash report. However, we need more information to investigate the crash. Please provide:

1. A backtrace generated from a core dump using the instructions provided on the Asterisk wiki [1].
2. Specific steps taken that lead to the crash.
3. All configuration information necesary to reproduce the crash.

Thanks!

Additionally, what channel driver is in use for SIP?

Is there anything additional in the Asterisk logs?

What Linux distribution and system is this running on?

Does this happen on Asterisk 18 as well?

As this problem is not constant, I will generate core dump and whenever it happen will share the details.
My system is live so I cannot switch on/off evertime because they have been used by agents.

Unfortunately this doesn't give us much information to figure out what's going on. We're going to need the core dump / backtraces to really get an idea of what's happening.
