IP telephony - how to find out who called?

Question

Telephony

Our company has ip-telephony, there were 26 calls to New Guinea at night that we did not make, how to find a person?

Answer 1

Contact your telephony provider, he will give you the ip addresses from which the calls were made.
Further, with a statement to the police, but there is no need to hope that a person will be found, no one will ever even look for him, just ask the provider to recalculate and read the contract with them again, you may have to go to court.

Answer 2

Apparently you are using an asterisk without proper protection. A simple tip on how not to get into even more money is to radically check the server and the security system. 26 calls is not an indicator. BUT it's a call.
In fact, you will not find the one who called. as a rule, single users do this extremely rarely, but cheap IP telephony services do not shun this. As a rule, hacking goes through black proxies that are extremely difficult to trace.

Answer 3

But it seems that the operator says that the network admin remotely could do this from our office?

Answer 4

Do you have a VoIP gateway within the network? Usually done this way, a connection to your gateway is set up and calls are made from it. Naturally, the provider's ip will be yours. called through you. You need to check the incoming connections on your equipment, it will be visible who called and when.
Naturally, the administrator could do this remotely. He could set up forwarding from the firewall to the VoIP gateway and call himself, or they could use it.

Answer 5

apparently you do not have an admin and you left your open ass on the Internet and any person with simple knowledge can call through you wherever he wants.
