Hello, I need help to understand what all these calls are, the firewall is activated and also the file 2ban. It’s a normal thing? Can they be blocked? Need to lock?

Thanks

No. Are you allowing anonymous connections?

Sure. Open 5060 to trusted sources only.

3

how do I define reliable sources for the 5060? where do i find the corresponding part? Unfortunately I don’t know

4

Allow only your SIP Provider and (if you have) remote offices IPs

5

do I always enter the sip provider in the firewall or are you talking about trunk - incoming?

6

can you give me some more indication

7

Sure, those CDR entries mean you have Allow SIP Guests and/or Allow Anonymous Callers enabled on the system. You should really turn those off.

10

OK so turn off Allow SIP Guests. Which is clearly enabled.

12

did i do it right?

13

Yes, that part. You still need to set up the Integrated Firewall to only allow your trusted IP address partners to access ports 5060/5160.

14

I activated the firewall, now it works very well! thank you all for the information, you have helped me in a practical way to resolve to perfection
