I got a call from an unknown number more specifically a no caller ID number. I’m not the guy who gets a lot of calls from a no caller ID phone number and usually when I got one is typically the hospital nothing suspicious. I know that in Canada and may by other countries, carriers allow to hide are numbers without any additional fee.
I’m currently researching ways to unmake a no caller ID number with Asterisk if possible. After digging online, the topic is not well documented. I know it’s possible and they are some company that offer this service like TrapCall and Opencnam.
How can I trap a call by myself?
Other mentions: In Canada it’s legal to trap a call but not in all country.
