No private module. The current kamailio.cfg is running under rhel 7/kamailio 5.0 with million requests per day and without any errors. It seems that if migration process (=> rhel 8 / kamailio 5.8) fails it is related to dispatcher module changes (attrs_avp, dst_avp...no longer available). I am not able to respond to the question "Do you process the SIP OPTIONS keepalives via event routes or the replies via reply routes in any way?"
Here is my dispatcher.list file: # # dispatcher destination sets # # gateways

Some lines commented out for 5.8 version.
I will try to build a simplified kamailio.cfg to reproduce the issue.
