sentrypeer

SentryPeer is a distributed list of bad IP addresses and phone numbers collected via a SIP Honeypot. SentryPeer is a fraud detection tool. It lets bad actors try to make phone calls and saves the IP address they came from and number they tried to call. Those details can then be used to raise notifications at the service providers network and the next time a user/customer tries to call a collected number, you can act anyway you see fit.

Only use this tool against systems you own or are explicitly authorized to test — see the disclaimer.
