Hello,
my device is getting calls from my device IP.
Let's say my IP is 1.1.1.1 then I get calls from 1.1.1.1.
I keep getting these calls every day like 40 times a day.
If I look into Call Detail Report in web interface then then I see Remote System name and also Call number 1 is 1012@1.1.1.1 or with 62977@ 1000@ and so on. I guess those numbers are ports that something or someone is trying to use. I heard there's something called as Toll Fraud but I guess that's not case because my device is just calling itself.
Is there a solution or an explaination to this or if there's a way whitelist IP's which can call to my device?
Best regards,
Einar
