I am using asterisk 11.9.0 everything works fine but cli shows unknown sip registrations with my current code running my cli output

how can i remove this because my dialplan is taking too much time to execute as compared to the past. Any help would be appreciated.
Very likly that is automated programs(bots) with goal find your secrets/on success call out to Cuba or other costly destinations.
Every asterisk installation need have at least rate limiter - usually fail2ban.org used. That will prevent bots from spamming too fast.
