sorry , no one will read this , please wrap your post up with proper code tags

hope this is better

Removed allow anonymous calls, no more strange incoming calls but still want to know what the calls are??

They were calls from people probing your system to try and make free calls on it.

Hello.

I have discovered the same issue.

I estimate bandwith montlhy by computing billseconds and I am normally to

1Gb.

Now I see 3.18Gb ?!

I analyzed to discover that, yes empty call from Israel DID or if for curiosity you remove the 9 then from Russia.

seem to be +972597885641 with prefix variation of 0011 / 011, etc.

At first I tryed to route the call from that particular DID to a voicemail,

then I thought that was futile hence yielding hanging up on voicemail.

Moreover the CDR has more than 2000 entries for august, with fake caller ID.

Yes seeing the variation they probe!

Finally the question is what do I loose if I disable anonymous calls?

Would that imply that someone need to be not confidential (not *67) to reach me?

Regards,

Eric

Why do you have SIP exposed to Internet?

Anyway…Anonymous SIP allows anyone to call you either by [email protected] or [email protected]

Turning it off only allows inbound calls from authenticated peers.

If you installed distro you would have fail2ban that will auto-block IP in iptables after x number of password misses.

Hello SkykingOH.

Thank you.

There is no reason at the very first. Freedom ?!

That is good I learn of it this way.

Sip trunk registered with correct inbound setting may be a good way, is that the authenticated way, that must be a way for me, with not allowing SIP guest !?

I allow anonymous for direct inbound call with STUN. I allow this also to be able to received confidential flagged calls. That is now THE reason why.

I have SRV records for inbound sip uri and my proxy in the ATA.

I have fixed this in moments of crash course.

I have setup the router allowing only SIP messages + RTP audio ports.

In my Linux PBX setup, I have setup iptables with very very fun chains,

isolating those ports with allowing the chain of ips associated with my providers.

I think I’m done !
