Since I'm increasingly receiving spam calls from foreign phone numbers on my landline, I've been wondering why the call blocking settings don't allow you to simply block all calls from a specific country using, for example, +91* or 0091*. I don't know anyone in that country anyway, so it doesn't matter if it's completely blocked. Alternatively, it would be an option to block all calls from abroad, not just from a specific country.

Unfortunately, the block list is limited, and since the spam calls always come from a different number, it's impossible.

If there's another TP-Link modem that offers this feature, I'd be happy to switch.
