You need to find out who is sending this 422 message. If it's one of
your end-points, then adapt the session-timer part of
/etc/ngcp-config/templates/etc/sems/etc/ngcp.sbcprofile.conf.tt2 to
something like this (note both the min/max timers), because then sems
will re-negotiate the interval up to the max timer value:

enable_session_timer=yes
session_expires=300
minimum_timer=90
maximum_timer=7200

After changing, execute "ngcpcfg apply".
