does not block all foreign calls

[Maxxxp]

I've blacklisted several emails with a "+" in front to identify them as foreign and block them, but the app doesn't always recognize it. It takes the number without the "+" and doesn't block it. The phone and another app correctly recognize that number with the "+."

Hi @Maxxxp,

thanks for the report and for the clear description.
I have a few ideas why this might be happening, but I need a bit more detail to be sure.
Could you please:

• send one or two example numbers that should be blocked but aren’t;
• ideally attach a screenshot from the Recent calls tab in Callfilter.app showing those calls;
• and a screenshot of your blacklist where these numbers are added?

This will let me compare how the numbers come from the network and how they are saved in the blacklist, and then I’ll try to reproduce and fix the issue.

Thanks for your help!

Thanks for the reply, I misspelled "emails" but you understood that I meant numbers, I'm attaching the requested images including one from my phone which recognizes them with the "+", for the filters I enabled the option to use "*"

I’ll need a bit more time to investigate the issue. I’ll get back to you shortly.

Hi @Maxxop,

thanks for the screenshots, they helped a lot.

I can see that in some cases Callfilter.app doesn’t normalize the number correctly and therefore doesn’t add the “+” at the beginning. This usually happens when the number is too short or doesn’t fully match the standard international format, so the app keeps it exactly as it comes from the network — without the “+”.

In your case the easiest workaround is to add additional blacklist prefixes without the plus sign. For example:

• if you now block +31*, also add 31*;
• if you block +33*, also add 33*;
• if you block +44*, also add 44* (and similarly for +34*, +36*, +46*, etc.).

In general, for every rule like +NN* please create an additional rule NN*.
This way the call will be blocked whether the operator sends the number with + or without it.

Please try this and let me know if it still misses some calls.
