How to enable srvlookup in PJSIP, Asterisk?

Question

Asterisk

Hello, I'm trying to call from outside to my zadarma account and I get the error
NOTICE[8458]: res_pjsip/pjsip_distributor.c:525 log_failed_request: Request 'INVITE' from '"[phone]" ' failed for '185.45.152.161:5060' (callid: 1b2dfba25e5ca94bb4444 @185.45.152.133:5060) - No matching endpoint found
As you can see, the ip is constantly changing.
What needs to be done to fix the error?
I work with PJSIP.

in type=identify I
added a match for groups of ip addresses that belong to the provider
