The P-cscf will exit every time. ### Troubleshooting I think it may related to the collaboration between tm module and ipsec module. #### Reproduction I set up a test environment according to the instructions https://open5gs.org/open5gs/docs/tutorial/02-VoLTE-setup/ . two iphones connetc to the EPC and attach to kamailio,and the IPSec is available. #### Debugging Data Here is the gdb info ``` Reading symbols from /usr/local/sbin/kamailio...done.
