VOIP Tech Chat → Re: [Voip.ms] CallerID filter not working

Skip the '1' at the start. Replace it with '*'. It will cover cases where the '1' is sent with the caller id or not.

Unfortunately, this will also filter out numbers like 6132888510.

why would that be?

Because *888* rule will filter 6132888510; * is replacing 1 or more digits. Instead is better to have 2 rules for each 8xx number how was already posted, in this case for 888 will be:
888XXXXXXX
1888XXXXXXX

If you use *888xxxxxxx, it covers the two examples you gave. I have used this setup for years and it works perfectly.

The question is will filter also other numbers like 6132888510 which is not desired?

Don't the XXXX's signify a specific number of digits? If so, *888xxxxxxx can only match 888 when it's followed by seven digits.

There's still a potential conflict with international numbers, though the odds of seeing such a conflict are pretty low.

I've tested the new query proposed by adding a bunch of filters to my own account and it seem to works fine. I've submitted the changes to our main programmer and it will be implement this week.

We'll also edit the Filter page to document the new order priority (From most specific to less specific, with some examples). An announcement will also be posted to make sure people who relied on order of addition are not affected by this and for you guys to be aware that the changes have been published.

Thanks all who contributed to this improvement.
