Hello,

I want to Block all calls from call src numbers and only allow some calls with specific src numbers which i allow globally. Is that possible ?
For Example,
I have 3 customers and they are sending calls, but i want reject all their calls and only allow calls from specific src number (CLI/ Caller ID) that i have allowed globally not specific customer vise.

You can use numberlist for this task.
